the vaccine or have happened without any cause.
Phase 3
The vaccine is then given to thousands of volunteers and compared with a similar group of people who didn’t get the vaccine but received a comparator product. This is done to determine if the vaccine is effective against the disease
it is designed to protect against and to study its safety in a much larger group of people. Most of the time, Phase 3 trials are conducted across multiple countries and multiple sites within a country to assure that the findings of the vaccine performance apply to many different populations. During Phase 2 and Phase 3 trials, the volunteers and
the scientists conducting the study are not informed whether the volunteers had received the vaccine being tested
or the comparator product. This is known as “blinding” and is necessary
to assure that neither the volunteers nor the scientists are influenced in their assessment of safety or effectiveness
by knowing which group had received which product. Once the trial is over and all the results are finalized, the volunteers and also the trial scientists are informed if they had received the vaccine or the comparator.
