The FDA also conducts ongoing monitoring of vaccine reactions. It tests everything from batches of the vaccine to the production process and the facilities for safety.
Unsure if this is a large enough test group? Consider this -– medicines in the United States also go through incredible scrutiny, but their test subject sample sizes are three times smaller than vaccine test subject groups.īut that's not the end of it: Once approved, the FDA continues to closely monitor the vaccine. The last phase involves a test group of up to tens of thousands of human volunteers. These trials usually take several more years to complete. Food and Drug Administration, at least three more phases of thorough clinical trials are conducted on human volunteers to test vaccine efficacy, to determine appropriate dosage, and to monitor for adverse side effects, etc. Once the test vaccine has been cleared for further investigation by the U.S.
The first step of this extensive process involves several years of laboratory research, in which scientists and researchers identify an antigen that can prevent a disease. The creation of a vaccine involves scientists and medical experts from around the world, and it usually requires 10 to 15 years of research before the vaccine is made available to the general public.
