The ongoing Phase 3 clinical trial of Pfizer/BioNTech's coronavirus vaccine confirms its protection lasts at least six months after the second dose, the companies said Thursday.

It's the first look at how long protection for a coronavirus vaccine lasts, and while six months is a modest target, it's longer than the 90 days of protection been the best estimate offered to date.

The vaccine remains more than 91% effective against disease with any symptoms for six months, the companies said. And it appeared to be fully effective against the worrying B.1.351 variant of the virus, which is the dominant strain circulating in South Africa and which researchers feared had evolved to evade the protection of vaccines, the companies said.

they said at least 6 months because it's too early too tell, not enough studies, data... and it could last a couple of years.
