Are the vaccines well tested?

Before vaccines are used on people, they undergo a very rigid approval process, which is always the same: the vaccine is tested on a great number of trial subjects, i.e. voluntary test persons who participate in studies.

The approval procedure was similar for the Corona vaccines, the only difference being that some of the so-called approval phases, which normally take place one after the other, were conducted simultaneously. This helped save much time and accelerate approval while complying with the highest safety standards.

Although the vaccines for Corona are the first mRNA vaccines to be approved, research into mRNA vaccines has been conducted for a very long time!
