Moderna has released the first batch of SARS-CoV-2 Vaccine for phase 1 trial.
Before a drug (and vaccine) is launched and marketed public use, it has to undergo rigorous testing.
Initially there is a pre-clinical phase in which tests are conducted in laboratory and on animals. After the drug is developed first it is tested on a small number of volunteers (20-100), in phase I trial, then gradually tested on larger population. i.e. 100-300 in phase II and 300-3000 in phase III. During these phases, the people who are given these drugs are carefully monitored for the development of any adverse effects. And if a drug passes all these phases only then it is made available in markets.
