In a recent update from Pfizer, the company has revealed that their vaccine is 95 percent effective against the earlier claims of showing 90 percent effectiveness against the vaccine. The vaccine candidate also passes the safety checks and claimed no serious side effects.

Meanwhile, Moderna has claimed that its experimental vaccine was 94.5 percent effective, based on interim data from a late-stage clinical trial.
