Adverse events associated with childhood vaccines other than pertussis and rubella. Summary of a report from the Institute of Medicine.

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.

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.” Clinical and Translational Science 2010

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.” CDC 2005

Post-licensure safety surveillance for Prevenar 13(®) in France

“RESULTS: In 4 years and 4 months, 376 AEs, including 252 severe (67%), were recorded, 83 of which occurred following an injection of Prevenar 13(®) alone: 39 cutaneous AEs, 16 neurological AEs, four cases of collapse or shock, nine cases of fever, and one of thrombocytopenia. For the serious AEs, the outcome was favorable in 88% of cases and none of the 12 reported deaths were attributed to a side effect of vaccination. Fifty-nine cases of pneumococcal disease that suggest an ineffective vaccine were reported, but only 16 can be considered as a real failure of the vaccination.” Archives De Pediatrie 2017

Questions regarding the safety and duration of immunity following live yellow fever vaccination.

“We found that antiviral immunity may be lost in 1-in-3 to 1-in-5 individuals within 5 to 10 years after a single vaccination and that children may be at greater risk for primary vaccine failure. The safety profile of YFV-17D was compared to other licensed vaccines including oral polio vaccine (OPV) and the rotavirus vaccine, RotaShield, which have subsequently been withdrawn from the US and world market, respectively. Expert commentary: Based on these results and recent epidemiological data on vaccine failures (particularly evident at >10 years after vaccination), we believe that current recommendations to no longer administer YFV-17D booster vaccination be carefully re-evaluated, and that further development of safer vaccine approaches should be considered.” Expert Review of Vaccines 2014

Reemergence of vaccinia virus during Zoonotic outbreak, Pará State, Brazil.

“In 2010, vaccinia virus caused an outbreak of bovine vaccinia that affected dairy cattle and rural workers in Pará State, Brazil. Genetic analyses identified the virus as distinct from BeAn58058 vaccinia virus (identified in 1960s) and from smallpox vaccine virus strains. These findings suggest spread of autochthonous group 1 vaccinia virus in this region.” Emerging Infectious Diseases journal 2013

Review of accidents caused by incomplete inactivation of viruses.

“Recent molecular evidence has now shown that formaldehyde-inactivated Venezuelan equine encephalitis vaccines were the probable cause of the outbreaks of the disease during the 1969-1972 pandemic in Central America. In the author’s opinion it is remarkable that formaldehyde is still used for the preparation of inactivated vaccines, particularly since it is known that the procedure also affects the immunogenic epitopes of the viruses.” Developments in Biological Standardization 1993 https://www.ncbi.nlm.nih.gov/m/pubmed/8174792/


Risk factors for measles vaccine failure among immunized students.

Rotavirus shedding in premature infants following first immunization

“CONCLUSIONS: The findings of this study demonstrate that premature infants have positive stools by EIA, viral culture, and RT-PCR at varying time points during 2 weeks following first-dose immunization with RV5. RT-PCR shedding rates need to be clinically evaluated in the context of virus quantification by cell culture, which was low. No symptomatic transmission to HHC {household contacts} was detected in this study, supporting low transmissibility of vaccine virus shed by these infants born prematurely.” Vaccine 2011

Secondary measles vaccine failures identified by measurement of IgG avidity: high occurrence among teenagers vaccinated at a young age.

“Failure to seroconvert (primary vaccine failure) is believed to be the principal reason (approx. > 95%) why some vaccinees remain susceptible to measles and is often attributed to the persistence of maternal antibodies in children vaccinated at a young age. Avidity testing is able to separate primary from secondary vaccine failures (waning and/or incomplete immunity), but has not been utilized in measles epidemiology.” Epidemiology and Infection 2000

Secondary transmission of varicella vaccine virus in a chronic care facility for children.

“A 16-year-old varicella-seronegative resident at a chronic care facility received varicella vaccine; 15 days later he developed severe varicella. Subsequently, a 13-year-old resident and a 39-year-old health care worker developed mild varicella. We demonstrate that vaccine-strain virus was transmitted to both persons, and that transmission included at least 2 variant vaccine strains.” Journal of Pediatrics 2006

Some ethical issues arising from polio eradication programmes 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.Bioethics 2005

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.” Vaccine 1989

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.” Journal of Clinical Microbiology 2011
