Why Phase 3 trial data is important ?

Under the phase 3 clinical  trial, investigators keep track of participants for at least six months after the last vaccine dose is administered . The data of those falling sick among the vaccinated and unvaccinated participants helps calculate the efficacy of the vaccine.

The trial also helps to  highlight the possible adverse affects of a vaccine. Favourable phase 3 results of the vaccine’s  efficacy and side-effects leads to the vaccines being approved for general human use.
