Pfizer's vaccine is only 39% effective against delta variant.

We had stated previously that Israel's proclamation of 64% efficacy for Pfizer was an overstatement and we've been proven right again.

What does this mean? This means that the delta variant will continue to spread in a fully vaccinated nation and vaccination is an untenable solution because a fully vaccinated and infected person can still spread the virus in the community.

We will continue to have multiple lockdowns whenever there is a covid resurgence unless we can find another way or a newly improved vaccine to deal with this virus.
