Question

How many cases of adverse reactions to vaccines have been reported annually to the Vaccine Adverse Event Reporting System since 1990?

1) 10,000
2) 20,000
3) 30,000
4) 40,000

Answer 1

The specific number of adverse reactions to vaccines reported annually to VAERS since 1990 cannot be provided as it varies each year and depends on several factors, such as vaccine distribution and public reporting awareness.

Step-by-step explanation:

The number of adverse reactions to vaccines reported annually to the Vaccine Adverse Event Reporting System (VAERS) varies each year, but none of the options provided (10,000, 20,000, 30,000, or 40,000) directly reflect the accurate numbers since 1990.

VAERS is a national system used in the United States to monitor the safety of vaccines after they are licensed. Healthcare providers are required to report any significant adverse events following vaccination, and while reporting is encouraged, it is voluntary for everyone else. Because these reports can vary greatly from year to year and depend on many factors such as the number of vaccine doses administered, public awareness of VAERS, and infectious disease outbreaks, there is no single annual figure since 1990 that can be accurately provided as an answer to this question.
