Pfizer efficacy 39% against Delta - Israel study

Some interesting news out of an Israel study on how effective Pfizer has been over there.

Health benefits appear to still be high however effectiveness appears to be fading dramatically. Everyone will need a booster shot only after 6'ish months.

This would now suggests a larger and much wider spread of Delta is now inevitable. Very slow wrecking ball this thing. Tail risk still incoming.
