A new peer-reviewed study about adverse events following immunization (AEFI) and the measles-mumps-rubella-varicella (MMRV) vaccine brings home the urgent need for independent research. The study, published by two northern Italian researchers on an open access platform suggests that most existing safety monitoring systems, whether in Italy or the U.S., are “utterly inadequate to document the real incidence of serious AEFIs and that current methods of assessing [vaccine-related] causality may be questioned.”
The Apulia researchers detected 992 post-MMRV adverse events among the 2,149 children for whom they were able to complete the three-week telephone follow-up — an AEFI reporting rate of 462 events per 1000 enrolled children. One hundred nine of the 992 adverse events (11%) met World Health Organization (WHO) criteria classifying them as “serious,” meaning fatal or life-threatening; requiring intervention or hospitalization; or causing persistent disability or incapacity.
All of the adverse events are listed as side effects in the package insert for the Merck-manufactured MMRV vaccine (brand name ProQuad) as well as in the inserts for a number of other childhood and adult vaccines. (Notably, the healthy 56-year-old Florida doctor who recently died after getting Pfizer’s mRNA COVID-19 vaccine developed an ultimately fatal form of thrombocytopenia three days after vaccination.)
The MMRV insert also lists dozens of other post-vaccination reactions, including anaphylaxis, febrile seizures, muscle and joint pain, arthritis, bleeding disorders, autoimmune problems and serious infections, including both measles and varicella (chickenpox)!Vaccine Injury Reporting Systems ‘Utterly Inadequate,’ Independent Researchers Say • Children’s Health Defense
