British study reveals AstraZeneca and Pfizer efficacy rates drop drastically within 3 months against the Delta variant

New studies based out of Britain show that the two most commonly used vaccines efficacy is diminished within three months against the Delta variant.

The study also shows that individuals who become infected after receiving both doses of Pfizer or AstraZeneca are of greater risk to others than previous strains.


The studies show that within 90 days after the second doses of Pfizer or AstraZeneca the efficacy rate drops to 75% and 61%.

The decline is greater in people ages 35 and up.
