Polio

Abortive and subclinical poliomyelitis in a family during the 1992 epidemic in The Netherlands.

“We describe a case of abortive poliomyelitis due to poliovirus type 3 (PV3) in an unvaccinated woman and a subclinical poliovirus infection in her family during an epidemic in the Netherlands. The woman excreted the epidemic strain (PV3) for 7 weeks. Her two children received oral attenuated poliovirus vaccine and were subsequently found to excrete PV1 and PV2 vaccine strains in addition to the epidemic PV3 strain. Her husband, who had neutralizing antibodies to all three poliovirus types because of previous vaccination, initially excreted no virus; subsequently, however, the vaccine strain PV1 and the epidemic strain PV3 could be cultured from his feces.”

Acute disseminated encephalomyelitis associated with oral polio vaccine.

“A 27-year-old woman presented with acute paresis after taking an oral polio vaccine (OPV). Deep tendon reflexes were preserved, needle electromyography showed no neurogenic changes, and there were no lesions on spine magnetic resonance imaging (MRI), suggesting that motor neurons of the spinal cord were not affected. Brain MRI showed abnormal lesions in the tegmentum of the upper pons, left cerebral peduncles, truncus of the corpus callosum, and right parietal lobe. Cerebrospinal fluid revealed mild pleocytosis. The most probable diagnosis was acute disseminated encephalomyelitis associated with OPV.”

“The committee found that the evidence favored acceptance of a causal relation between diphtheria and tetanus toxoids and Guillain-Barré syndrome and brachial neuritis, between measles vaccine and anaphylaxis, between oral polio vaccine and Guillain-Barré syndrome, and between unconjugated Hib vaccine and susceptibility to Hib disease. The committee found that the evidence established causality between diphtheria and tetanus toxoids and anaphylaxis, between measles vaccine and death from measles vaccine-strain viral infection, between measles-mumps-rubella vaccine and thrombocytopenia and anaphylaxis, between oral polio vaccine and poliomyelitis and death from polio vaccine-strain viral infection, and between hepatitis B vaccine and anaphylaxis.”

The African polio vaccine-acquired immune deficiency syndrome connection.

“Seroepidemiological, clinical and molecular findings suggest that the acquired immune deficiency syndrome virus human immunodeficiency virus-1 was introduced into the human species at the time (late 1950s) and in the geographic area (Zaire) in which millions of Africans were vaccinated with attenuated poliomyelitis virus strains that were produced in kidney tissue obtained from monkeys. Since monkeys not only harbor viruses that are remarkably similar to and genetically related to human immunodeficiency virus-1, but also served as tissue donors for the African polio vaccine, it is reasonable to suspect that a then non-detectable monkey virus with human-1-like properties was unknowingly co-cultured with the attenuated poliovirus virus and subsequently administered to the vaccinees. The possibility of such a polio vaccine-acquired immune deficiency syndrome connection is a reminder of the unpredictable danger of artifically crossing natural species-barriers in biomedical laboratories.”

🛑 Assessment of iatrogenic transmission of HCV in Southern Italy: was the cause the Salk polio vaccination? 

“Since the first studies on hepatitis C virus (HCV) prevalence were published, it has been evident that southern Italy is an area of hyperendemicity. A recent study conducted in southern Italy suggested that the high prevalence of HCV infection might be the result of past iatrogenic transmission. Polio vaccination with the parenteral Salk vaccine between 1956 and 1965 by multiple use of unsafe glass syringes may have been one of the major causes of the spread of HCV infection among southern Italian adults who are now older than 40 years of age. Persons born between the 1940s and early 1960s have a nearly 3-fold increased risk of HCV seropositivity than the younger age group. The findings are consistent with a cohort effect of exposure to the Salk parenteral vaccination.”

Bridging the gap: human diploid cell strains and the origin of AIDS.

“Although the theory of a chimpanzee origin of HIV-1 with cross-species transfer to man has now gained popularity, a more likely scenario is that chimps and humans were infected by an HIV-1 precursor virus derived from a contaminated poliovaccine. The reason for the rapidity and ease of cross-species transfer of this precursor virus has not been elucidated. We hypothesize that the poliovaccine was passaged in a human diploid cell strain.”

Characteristics of poliovirus strains from long-term excretors with primary immunodeficiencies.

“Individuals who are deficient in humoral immunity are particularly at risk from infection with enteroviruses, and poliovirus in particular, where antibodies are the main source of protection from disease. Long-term excretion of vaccine strains of poliovirus has been documented for many years and instances of paralytic poliomyelitis in hypogammaglobulinaemic patients who were subsequently found to have been excreting virus for prolonged periods have been reported in the U.S.A., Germany and Japan. The identification of a healthy immunodeficient patient in the U.K. who has probably been excreting type 2 poliovirus for 15 years will be described, with the characteristics of the virus and the results of attempts at treatment so far. Such individuals pose a significant risk to the eradication programme unless they can be identified and treated.”

Don’t ignore the risk of vaccine contamination

“Sir, Your News and Opinion articles about alleged contamination of vaccines should serve as a warning against over-optimism.

These articles highlight the failure to show any evidence for contamination of Wistar Institute polio vaccine stocks by human and simian immunodeficiency viruses (HIV/SIV), and you appeal for a truce. But — although Edward Hooper is quoted as saying that “vaccine samples released did not include any from batches prepared for use in Africa” — lymphocytes have been detected in other polio vaccines. Half of the vervet monkeys in Southern Africa are SIV positive; these animals were used for preparing early polio vaccines.

Considering the many millions of vaccine doses prepared in primary vervet monkey kidney cultures over a 30-year period, it is inconceivable that some SIV did not contaminate many cultures. By the same yardstick, simian virus 40 (SV40) contaminated millions of doses of poliovirus vaccine until the animals were screened for this tumour virus.

Edward Hooper and others surely do not intend to undermine the polio vaccine efforts. What is needed is a new awareness of the need for caution — remembering the example of BSE — in view of the current impetus towards xenotransplantation and the accompanying danger of contamination. Our aim should be to improve our vaccines, not to undermine public confidence in them.”

Effect of prior immunity on the shedding of virulent revertant virus in feces after oral immunization with live attenuated poliovirus vaccines.

“Groups of infants were immunized with one or two doses of orally inoculated live attenuated Sabin poliovirus vaccine (OPV group) or with one or two doses of enhanced-potency inactivated poliovirus vaccine (EIPV) administered parenterally followed by one or two doses of OPV (EIPV-OPV group). The fecal specimens from both groups were tested for poliovirus shedding 1-2 months after OPV. The virus isolates were examined for nucleic acid sequences in the 5′ noncoding regions (bases 480, 481, and 472 for serotypes 1, 2, and 3, respectively) to determine whether the viruses shed represented nonattenuated revertants, attenuated parent vaccine strains (nonrevertants), or both. In the OPV group, 4 of the 6 virus isolates recovered 30-60 days after the first immunization dose and 1 of the 3 isolates obtained after the second dose were found to be nonrevertants (parent vaccine strain). In contrast, 11 of the 12 isolates in the EIPV-OPV group were of the nonvaccine revertant virus types. The frequency for reversion appeared to differ for different poliovirus serotypes. However, all revertant type 3 isolates were recovered from subjects previously immunized with EIPV.”

“Although only 114 virologically-confirmed paralytic cases were identified in the eight cVDPV outbreaks, it is likely that a minimum of hundreds of thousands, and more likely several million individuals were infected during these events, and that many thousands more have been infected by VDPV lineages within outbreaks which have escaped detection.”

Estimation of polio infection prevalence from environmental surveillance data. 2017

“By measuring virus shed into sewage waste in cities in which a known number of people received a live polio vaccine, the authors created tools that can be used to monitor polio incidence in other cities. Thus, virus levels in sewage waste can give an early warning of the reappearance of viral disease or verify its absence.”

“Data from the intersecting population between the two data sets (covering more than 63,000 people) yielded a dose-dependent relationship between the number of poliovirus shedders and the amount of poliovirus in sewage.

🛑 Experimental oral polio vaccines and acquired immune deficiency syndrome.

The simian immunodeficiency virus (SIV) of the common chimpanzee is widely acknowledged as the direct ancestor of HIV-1. There is increasing historical evidence that during the late 1950s, kidneys were routinely excised from central African chimpanzees by scientists who were collaborating with the polio vaccine research of Dr Hilary Koprowski, and sent – inter alia – to vaccine-making laboratories in the USA and Africa, and to unspecified destinations in Belgium. While there is no direct evidence that cells from these kidneys were used as a substrate for growing Dr Koprowski’s oral polio vaccines, there is a startling coincidence between places in Africa where his CHAT vaccine was fed, and the first appearances in the world of HIV-1 group M and group-M-related AIDS. Because of the enormous implications of the hypothesis that AIDS may be an unintended iatrogenic (physician-caused) disease, it is almost inevitable that this theory will engender heated opposition from many of those in the scientific establishment, and those with vested interests.

Fetal damage after accidental polio vaccination of an immune mother.

“Irreparable damage to the anterior horn cells of the cervical and thoracic cord was found in a 20-week-old fetus whose mother was immune to poliomyelitis before conceiving but who was inadvertently given oral polio vaccine at 18 weeks gestation. Polio neutralizing antibody titres in sera, taken before and after pregnancy, were identical and were at levels normally regarded as providing protection. Unsuccessful attempts were made to isolate poliovirus from extracts of fetal brain, lung, liver and placenta. Fluorescent antibody tests were performed on various levels of the central nervous system and on the left and right extensor forearm muscles. Specific positive fluorescence to poliovirus 2 and 3 antigens was detected at dorsal spinal cord level only. One positive result was seen with Coxsackie A9 antiserum and fresh guinea-pig complement in the inflammatory cells in the right extensor forearm muscles.This experience, as yet unexplained, underlines the importance of ensuring that women are not pregnant prior to oral polio vaccination.”

A classification of clinical disorders associated with FA based on classic mechanisms of immunologic injury is presented, which includes the following: (1) IgE-mediated, (2) non-IgE-mediated, and (3) mixed IgE- and non-IgE-mediated disorders. Our study of immunologic disturbance in patients with non-IgE FA revealed a pattern of increased CD4+ and decreased TH1 cell counts in peripheral blood mononuclear cells in contrast to patients with celiac disease, where a pattern of increased CD8+ and TH1 cell counts in peripheral blood mononuclear cells and increased CD8+ cell counts was seen.”

Guillain-Barre syndrome occurring after rabies vaccination.

“A variety of events are associated with the onset of Guillain-Barre syndrome, including vaccinations and vaccines. These are the swine influenza vaccine, oral poliovirus vaccine and rabies vaccine. Rabies is a uniformly fatal disease. It is preventable if World Health Organization (WHO) guidelines for post exposure treatment (PET) are followed. These include local treatment of wound, passive immunization with rabies immunoglobulins and administration of a efficacious vaccine. Cell culture vaccines are highly immunogenic with fewer side effects, but are costly. For that reason neurotissue vaccines are still widely used in Pakistan, although they are less immunogenic with higher incidence of neuroparalytic complications. We report a case of Guillain-Barre syndrome secondary to sheep brain anti-rabies vaccine in a young boy, who presented with lower limb weakness with total recovery after treatment.”

Human and animal vaccine contaminations.

“However, since vaccine preparation involves the use of materials of biological origin, vaccines are subject to contamination by micro-organisms. In fact, vaccine contamination has occurred; a historical example of vaccine contamination, for example, can be found in the early days of development of the smallpox vaccine. The introduction of new techniques of vaccine virus production on cell cultures has lead to safer vaccines, but has not completely removed the risk of virus contamination. There are several examples of vaccine contamination, for example, contamination of human vaccines against poliomyelitis by SV40 virus from the use of monkey primary renal cells. Several veterinary vaccines have been contaminated by pestiviruses from foetal calf serum. These incidents have lead industry to change certain practices and regulatory authorities to develop more stringent and detailed requirements. But the increasing number of target species for vaccines, the diversity of the origin of biological materials and the extremely high number of known and unknown viruses and their constant evolution represent a challenge to vaccine producers and regulatory authorities.”

🛑 LESSONS FROM THE SALK POLIO VACCINE: METHODS FOR AND RISKS OF RAPID TRANSLATION

“Regretfully, the story of polio vaccine was not without tragedy. In April 1955, soon after mass polio vaccination began in the United States, reports trickled in to the Surgeon General concerning atypical cases of paralytic polio. Several paralytic polio cases were reported in California in patients who had received the polio vaccine about a week earlier but the paralysis only affected the arm or leg in which they received the injection. Each of these cases occurred in polio vaccine produced by Cutter pharmaceutical company. The Surgeon General immediately pulled all Cutter polio vaccine, but it was too late; nearly 400,000 children had been inoculated with Cutter polio vaccine and 250 cases of atypical paralytic polio occurred. There were also reports of the Wyeth pharmaceutical company polio vaccine causing paralysis and death in several children in the northeastern United States.

It was soon discovered that some lots of Cutter and Wyeth polio vaccine were insufficiently inactivated with formalin leading to live polio virus in more than 100,000 doses. In fact, 16 lots of Cutter polio vaccine were retested and the first 6 lots produced were positive for live polio virus. These incidents demonstrated the lack of oversight and safeguards put into place before the vaccine was made so widely available.”

Live oral poliovirus vaccines and simian cytomegalovirus.

“Live oral poliovirus vaccines (OPV) are often produced in primary Cercopithecus monkey kidney (CMK) cells. The kidneys of these monkeys are often latently infected with simian cytomegalovirus (SCMV), and CMK cultures are frequently contaminated with SCMV. We tested human, monkey and rabbit tissue culture systems, and found that MRC-5 cells are most sensitive for detection of SCMV. To address the question of whether OPV could be contaminated with infectious SCMV, we inoculated MRC-5 cells with neutralized OPV manufactured in the United States between 1972 and 1998. Infectious SCMV was not found in any of the vaccine lots tested. We also used the polymerase chain reaction (PCR) to search for SCMV DNA in live oral poliovirus vaccines; SCMV DNA sequences were found in several of the vaccine lots manufactured prior to 1992.”

Neuropathology of vaccination in infants and children.

“AIMS: Documentation of clinical-pathological features of 37 infants/children whose parents alleged a relationship between vaccination and death or permanent central nervous system (CNS) damage, and sought compensation through the National Vaccine Injury Compensation Program.

SCOPE: Of the 5545 claims filed during the 10-year period (1990-1999), CNS tissue was available for evaluation by a pediatric neuropathologist in 37; 33 died and 4 had a biopsy or lobectomy. Most commonly implicated vaccines were DTP/DTaP, followed by MMR and IPV/OPV, but almost all of the vaccines currently given to infants/children were alleged to be responsible for the illness/death. No lesions were found in 5 of 37 (13.5%). The most frequent abnormality consisted of acute anoxic encephalopathy (14 of 37 – 37.8%), consequent to several different causes, such as positional asphyxia, cardio-respiratory arrest during status epilepticus, etc. The remaining children manifested other lesions, including inflammation (5 of 37 – 13.5%), vascular and developmental anomalies (4 each of 37 or 10.6%), cerebral edema and system degeneration (2 each of 37 or 5.4%), and one case of heavy metal exposure in a child living near an abandoned mine (2.2%).”

🛑 Oral polio vaccine and human cancer: a reassessment of SV40 as a contaminant based upon legal documents. 

“The confirmation of the removal by one drug manufacturer, Lederle, has been made public at an international symposium in January 1997, where its representatives stated that all of Lederle’s seeds had been tested and screened to assure that it was free from SV40 virus. However, in litigation involving the Lederle oral polio vaccine, the manufacturer’s internal documents failed to reveal such removal in all of the seeds. The absence of confirmatory testing of the seeds, as well as testimony of a Lederle manager, indicate that this claim of removal of SV40 and the testing for SV40 in all the seeds cannot be fully substantiated. These legal documents and testimony indicate that the scientific community should not be content with prior assumptions that SV40 could not have been in the oral polio vaccine.”

Oral poliovaccine: will it help eradicate polio or cause the next epidemic?

“RESULTS: Characterization of poliovirus from sewage revealed eight type 2 and three type 3 vaccine polioviruses that had replicated and started to evolve (vaccine that replicated and diverged by 0.5 to < or = 1.0%) and nine highly diverged type 2 vaccine-derived polioviruses (1-15% divergence from the respective Sabin strain) with 8-14% divergence between the years 1998 and 2005. Six of the eleven VRPV uniquely recombined with OPV and/or NPEV. The nine VDPV were epidemically related, genotypically neurovirulent, and had 10-15 amino acid substitutions in antigenic sites altering their antigenicity, but shared a single recombination. Type 2 OPV was excreted by 23% and 17% of infants challenged with OPV 3 months after partial immunization (two doses each of OPV and enhanced inactivated poliovirus) or full immunization (three doses of each) respectively, despite high humoral antibody titers. CONCLUSIONS: Our findings, which show that OPV is excreted for a significant period by children with high humoral immunity, emphasize the long-term potential threat from VDPV in highly vaccinated populations." #Shedding #Polio #Vaccine #MedScienceResearch https://www.ncbi.nlm.nih.gov/m/pubmed/16805227/

“Scientific discussion of the polio vaccine hypothesis for the origin of acquired immune deficiency syndrome (AIDS) has been systematically suppressed for more than 12 years. The author calls for an international multidisciplinary inquiry into the origin of AIDS, arguing it is essential to human health, prevention of new pandemics, and to protect the integrity of science in the eyes of the public.”

Outbreak of poliomyelitis in Hispaniola associated with circulating type 1 vaccine-derived poliovirus.

“An outbreak of paralytic poliomyelitis occurred in the Dominican Republic (13 confirmed cases) and Haiti (8 confirmed cases, including 2 fatal cases) during 2000-2001. All but one of the patients were either unvaccinated or incompletely vaccinated children, and cases occurred in communities with very low (7 to 40%) rates of coverage with oral poliovirus vaccine (OPV). The outbreak was associated with the circulation of a derivative of the type 1 OPV strain, probably originating from a single OPV dose given in 1998-1999. The vaccine-derived poliovirus associated with the outbreak had biological properties indistinguishable from those of wild poliovirus.”

“Oral polio vaccine (OPV) has failed to provide full protection to many children who have developed paralytic polio even after taking 10 or more doses of OPV. In some children, OPV has caused paralysis-vaccine associated paralytic polio (VAPP). Number of children developing polio due to vaccine is high and on increase.”

Polio vaccines and the origin of AIDS.

“In particular, it is now known that the early polio vaccines were contaminated with at least one monkey virus, SV40. The transfer of monkey viruses to man via contaminated vaccines is particularly relevant to the acquired immunodeficiency syndrome (AIDS), since the causative agent of AIDS, human immunodeficiency virus (HIV), is thought to be derived from a simian precursor virus. Furthermore, human infection with this virus appears to be a relatively recent event. We hypothesize that the AIDS pandemic may have originated with a contaminated polio vaccine that was administered to inhabitants of Equatorial Africa from 1957 to 1959. The mechanism of evolution of HIV from this vaccine remains to be determined.”

Poliovirus Infections in Four Unvaccinated Children — Minnesota, August–October 2005

“On September 29, 2005, the Minnesota Department of Health (MDH) identified poliovirus type 1 in an unvaccinated, immunocompromised infant girl aged 7 months (the index patient) in an Amish community whose members predominantly were unvaccinated for polio. The patient has no paralysis; the source of the patient’s infection is unknown. Subsequently, poliovirus infections in three other children within the index patient’s community have been documented.”

“Partial sequencing of the virus capsid protein coding region (VP1) of the poliovirus genome at the MDH laboratory identified it as a vaccine-derived poliovirus (VDPV). VDPVs are poliovirus strains derived from one of the three Sabin poliovirus strains in oral polio vaccine (OPV) that have >1% difference in nucleotide sequence from the prototype vaccine virus.”

Preparation for global introduction of inactivated poliovirus vaccine: safety evidence from the US Vaccine Adverse Event Reporting System, 2000-12.

“Of the 41,792 adverse event reports submitted, 39,568 (95%) were for children younger than 7 years. 38,381 of the reports for children in this age group (97%) were for simultaneous vaccination with IPV and other vaccines (most commonly pneumococcal and acellular pertussis vaccines), whereas standalone IPV vaccines accounted for 0·5% of all reports. 34,880 reports were for non-serious events (88%), 3905 reports were for non-fatal serious events (10%), and 783 reports were death reports (2%). Injection-site erythema was the most commonly coded term for non-serious events (29%), and pyrexia for non-fatal serious events (38%). Most deaths (96%) were in children aged 12 months or younger; most (52%) had sudden infant death syndrome as the reported cause of death.”

Risks of reintroduction of polio after eradication: the vaccine origin of an outbreak of type 3 poliomyelitis.

“In this report, we have examined virological and epidemiological aspects of an epidemic of poliomyelitis in 1968 in Poland that was shown to be associated with the use of the USOL-D-bac live-attenuated vaccine strain. Possible causes of the origin and progress of the outbreak included the pattern of virus excretion from vaccinees, mutations identified in epidemic viruses and the unique vaccination policies in Poland during the years preceding the epidemic.”

Simian cytomegalovirus and contamination of oral poliovirus vaccines.

“In the 1950s the use of primary rhesus macaque kidney cultures to propagate poliovirus for vaccine production led to the contamination of vaccines with simian virus 40 (SV40). African green monkey kidney (AGMK) cultures free of SV40 were used as an alternative cell substrate for vaccine manufacture. In this study we evaluate oral poliovirus seeds, vaccine bulks and vaccines themselves for the presence of a common contaminant of AGMK cultures, simian cytomegalovirus (SCMV). Using sensitive polymerase chain reaction (PCR) techniques, nearly half of the samples analysed were found to be contaminated with SCMV sequences. However, vaccine bulks, positive by PCR for SCMV failed to show any evidence of infectious virus in these studies. One poliovirus vaccine and one seed, propagated on rhesus macaque kidney cultures were found to be positive for the rhesus monkey CMV by PCR.”

Some ethical issues arising from polio eradication programmes in India.

“The issue of risks and benefits arises in relation to the choice between two different vaccine types available for polio programmes: oral polio vaccine (OPV) and inactivated polio vaccine (IPV). OPV is the vaccine currently used in the eradication campaign in India. We argue that given the current risks/benefits profile of this vaccine, there is an urgent need to review the programme and take remedial action to address existing problems (at least in India). The second issue we discuss is the fact that there is little effort to gain the informed consent of the parents of vaccinated children, as they are not currently told about the potential limitations of OPV or the possibility of vaccine-induced harm.”

Surveillance of suspected poliomyelitis in Albania, 1980-1995: suggestion of increased risk of vaccine associated poliomyelitis.

“Poliovirus was isolated from six subjects who were defined as contact vaccine-associated cases. Characterization of isolates by both antigenic and molecular methods showed that, in all cases, the disease was associated with type 2 or 3 polioviruses of vaccine origin with retromutations known to be associated with loss of Sabin attenuated phenotype. Infection occurred despite the fact that all patients had records of previous immunization with oral polio vaccine (OPV), suggesting a failure of vaccination.”

[SV40 as a possible cofactor in the etiopathogenesis of mesothelioma and other human tumors].

“Simian virus 40 (SV40) has been introduced into the human population with contaminated polio vaccines between 1955 and 1963. Previous research conducted by southern blot hybridization and recent analysis by PCR have shown the presence of SW0 sequences in human brain tumors, mesotheliomas and osteosarcomas as well as in normal tissues such as blood and sperm fluids. SV40 RNA and T antigen were detected in the same tissues. All the samples were coinfected by BK Virus (BKV), suggesting that BKV may have a helper function for SV40 replication in human cells. The presence of SV40 in human tumors suggests that the virus may be a cofactor in the etiopathogenesis of human neoplasia. In addition, blood and semen may represent the vectors for transmission of SV40 by horizontal infection in the human population.”

Use of a novel real-time PCR assay to detect oral polio vaccine shedding and reversion in stool and sewage samples after a mexican national immunization day.

“During replication, oral polio vaccine (OPV) can revert to neurovirulence and cause paralytic poliomyelitis. In individual vaccinees, it can acquire specific revertant point mutations, leading to vaccine-associated paralytic poliomyelitis (VAPP). With longer replication, OPV can mutate into vaccine-derived poliovirus (VDPV), which causes poliomyelitis outbreaks similar to those caused by wild poliovirus. After wild poliovirus eradication, safely phasing out vaccination will likely require global use of inactivated polio vaccine (IPV) until cessation of OPV circulation.”

Vaccine-associated contact paralytic poliomyelitis with atypical neurological presentation.

“Paralytic poliomyelitis presenting with quadriparesis, transient encephalitis and bulbar symptoms in 2 patients in close contact with recently vaccinated children with trivalent live oral polio vaccine is described. Symmetrical lower motor neuron involvement of deltoid muscles with electromyographic confirmation was found. Upper motor neuron signs, with symmetrical hyperactive deep tendon reflexes developed in the lower extremities. Poliovirus Type-2 vaccine-like strain was cultured from one patient and both patients showed significant antibody titers rises to poliovirus. Attention is drawn to the possible clinical differences between vaccine associated poliomelitis and the usual features found in wild strain poliomyelitis. It is suggested that in selected cases, non-immunized contacts be given inactivated polio-vaccine when the vaccinees are immunized with the live oral-vaccine.”

Neurological and electrophysiological examinations suggested that his muscular wasting of the left lower limb was due to a lower motor neuron disorder, and magnetic resonance imaging revealed the responsible lesion in the left anterior horn at the thoracolumbar junction. His stool was found to include poliovirus type 3, mainly originating from Sabin 3 by neutrization antibody and PCR-restriction fragment length polymorphism method. This indicated that the AAP resulted from contact with his son.”

The epidemic followed small-scale trials with Sabin and USOL-D-bac type 3 vaccine strains carried out in seven countries including Poland. Factors that might have contributed to the genesis and development of the epidemic were the pattern of virus excretion from vaccinees, mutations found in viruses from the epidemic, and the particular vaccination policies in Poland during the previous years.”

🛑 [Vaccines, biotechnology and their connection with induced abortion].

“Diploid cells (WI-38, MRC-5) vaccines have their origin in induced abortions. Among these vaccines we fi nd the following: rubella, measles, mumps, rabies, polio, smallpox, hepatitis A, chickenpox, and herpes zoster. Nowadays, other abortion tainted vaccines cultivated on transformed cells (293, PER.C6) are in the pipeline: flu, Respiratory Syncytial and parainfluenza viruses, HIV, West Nile virus, Ebola, Marburg and Lassa, hepatitis B and C, foot and mouth disease, Japanese encephalitis, dengue, tuberculosis, anthrax, plague, tetanus and malaria. The same method is used for the production of monoclonal antibodies and other proteins, gene therapy and genomics. Technology enables us to develop the aforementioned products without resorting to induced abortion. Full disclosure of the cell origin in the labelling of vaccines and other products must be supported. There are vaccines from non-objectionable sources which should be made available to the public. When no alternative vaccines exist, ethical research must be promoted. Non-objectionable sources in the production of monoclonal antibodies, gene therapy and genomics must be encouraged. It is not be consistent to abstain from products originated in embryonic stem cells and at the same time approve of products obtained from induced abortions. It is of paramount importance to avoid that induced abortion technology seeps into every field of Medicine.”
