Get The Information You Need About Vaccine Reactions
In 1986, Congress passed the National Childhood Vaccine Injury Act (PL-99-660) that among other things required healthcare providers to report vaccine reactions to a centralized reporting system. As a result the Vaccine Adverse Events Reporting System (VAERS) to which parents, physicians and vaccine manufacturers could report adverse events was created. NVIC has assisted many parents in reporting adverse events following vaccination as many doctors refuse to make a report. It is estimated that only 1-10% of all doctors report a severe health problem which occurs after a drug or vaccine is given to a patient.
In May 1990 we started to track DPT vaccine lot numbers when parents reported their child’s hospitalization, injury or death following vaccination to NVIC. Evaluating adverse event reports from more than 90 families, we found multiple serious reports were from the same vaccine lot numbers. NVIC made three separate presentations to government advisory committees between 1990 and 1993, but no substantive action was ever taken by the FDA or CDC.
Upon further investigation when the VAERS computer data became available through the Freedom of Information Act, we found (1) a lack of reporting by health care providers; (2) a lag time between when the adverse event occurred and when the report is filed; (3) data entry errors; (4) duplicate reports; (5) inadequate follow-up by the government of reported serious injuries and deaths; (6) many lots with very high numbers of reports; and (7) no recall of any lot of vaccine. We do not know how many doses of vaccine are in each lot because the FDA and the drug companies do not release this information to the public. Therefore, it is impossible to precisely compare one lot to another for reactivity.
The old, whole cell DPT vaccine is no longer used in the United States. The U.S. now uses an acellular version of the pertussis vaccine which is a more purified vaccine.
In the past fifty years reports of “hot lots” of vaccines, those that appear to be associated with more injuries and deaths than others, have been reported in the United States and Europe.
For many years, NVIC used a computer programmer to analyze the data to determine if “hot lots” were appearing. Because the data is now available on-line, we suggest you search or download the database and check the lot numbers for yourself.
If you suspect that you or your child has experienced a vaccine reaction, report that reaction to the government at the Vaccine Adverse Events Reporting System. Due to reporting of adverse events, the rotavirus vaccine was removed from the market for causing bowel obstructions in infants and children.
You can also report a reaction to the National Vaccine Information Center. We have kept a vaccine adverse event database since 1982. To report a reaction to NVIC.
