Would we be having a third dose of COVID-19 Vaccine as a Booster ?

Yes, it is a possibility that a third booster dose of COVID vaccine would be offered later this year.

Vaccination has been tremendously successful so far. But it is too early to declare victory against the virus.

Data from Israel indicates that the current Pfizer vaccine, although still highly active, offers less protection against delta variant.

In June, the vaccine was found to be just 64 percent effective in preventing coronavirus infection whereas during May, when the delta strain was less prevalent, the vaccine was 94.3% effective.

So if more variants emerge, then vaccine boosters may be particularly needed for the vulnerable people.
