however, rare adverse events may not be detected in prelicensure testing and can only be detected by postmarketing surveillance as the vaccine becomes widely used. the u.s. food and drug administration receives reports from manufacturers, pharmacists, physicians, and the military services of adverse events following immunization. all reports of events associated with mmr vaccine are attributed to each of the vaccine antigens, making the rates of reported events for measles, mumps, and rubella antigens appear approximately the same.
when arthralgia and arthritis associated with single-antigen rubella vaccine are added to those events that are attributed to mmr vaccine, rubella antigen has the highest reported rate of adverse events (table 4). except for a single sids death, which was temporally associated with the administration of inactivated polio vaccine (ipv) in 1982, all sids deaths were reported in temporal association with dtp or dtp and opv vaccine administration. as an example, a comparison of personal history of convulsions in those who had convulsions following receipt of dtp was compared with those who had other (nonneurologic) adverse events following receipt of dtp (table 6). the increases in reported rates of adverse events during the 4-year period are probably due to improved reporting, as would be expected during the first years of implementation of the surveillance system.
some parents or patients question the need for or safety of vaccinations and want to discuss the risks from and benefits of certain vaccines. websites and other sources of vaccine information may be inaccurate or incomplete. in 2005, the vaccine adverse event reporting system (vaers) began detecting a trend of increasing syncope reports that coincided with the licensure of 3 vaccines for adolescents: human papillomavirus (hpv), menacwy, and tdap (4). the best practice to prevent allergic reactions is to identify individuals at increased risk by obtaining a history of allergy to previous vaccinations and vaccine components that might indicate an underlying hypersensitivity. in general, a history of a severe allergic reaction to a vaccine should be considered a contraindication to additional doses of the same vaccine (13). a previous severe allergic reaction to influenza vaccine, regardless of the component suspected to be responsible for the reaction, is a contraindication to future receipt of the vaccine (14).
the rare severe allergic reactions after measles- or mumps-containing vaccines or varicella are thought to be caused by other components of the vaccine (e.g., gelatin) (21-24). a local or delayed-type hypersensitivity reaction to thimerosal is not a contraindication to receipt of a vaccine that contains thimerosal (34). more complete information about adverse reactions to a specific vaccine is available in the package insert for each vaccine and from cdc. the national childhood vaccine injury act of 1986 (1) requires health care personnel and vaccine manufacturers to report to vaers specific adverse events that occur after vaccination. additional information is available from the health resources and services administration (hrsa)external icon or by telephone at 800-338-2382. persons who would like to file a claim for vaccine injury should contact the u.s. court of federal claims (717 madison place, n.w., washington, dc 20005; telephone: 202-357-6400). non–weight-based dosing can be used if the patient’s weight is not known and cannot be estimated.
vaers accepts and analyzes reports of possible health problems—also called “adverse events”—after vaccination. as an early warning system, vaers cannot prove some people have no side effects. many people have reported side effects, such as headache, fatigue, and soreness at the injection site, that are generally systemic reactions include fever, headache, body aches, fatigue, etc. these reactions are usually mild and can last for several days. source: chapter 2 general, cdc adverse reactions to covid vaccine, covid vaccine error reporting, covid vaccine error reporting, pfizer side effects, pfizer side effects after 1 week.
seventy-eight deaths were reported among vaccine recipients during the 4-year period; 45 (58%) of these were classified as sudden infant death syndrome (sids). during that time, over 1.6 million vaccine recipients enrolled in v-safe, and vaers received 6,994 reports of adverse events following vaccination. about 91% of reporting vaccine safety emergencies and events of concern requiring vaccine safety responses to the cdc immunization safety office (404-498-0680) or the cdc, report side effects of j&j vaccine, vaers myocarditis 2021, vaers id 1074247, the vaccine adverse events reporting system is quizlet.
