VHA Study of 620,000 Shows COVID Vaccine Efficacy Decline

There was a Veteran Health Administration Study of 620,000 people that showed the decline in COVID Vaccine effectiveness from February 1 to Mid August, 2021.
Overall vaccine protection was down to 53.9% in August 13 from 92% in March.
J&J vaccine protection was down to 3% in August. The J&J vaccine is almost no protection after about three months.
The Pfizer vaccine effectiveness was 50% in August.
Moderna provided 64% protection in August.
The Nextbigfuture extrapolation to late October is 15-30% effectiveness Pfizer, J&J nothing, Moderna 25-40%. Booster shots are needed to re-establish some effectiveness. The decline was the shift to the delta variant and the decline over time.

Abstract

National data on COVID-19 vaccine breakthrough infections is inadequate but urgently needed to determine U.S. policy during the emergence of the Delta variant. We address this gap by comparing SARS CoV-2 infection by vaccination status from February 1, 2021 to August 13, 2021 in the Veterans Health Administration, covering 2.7% of the U.S. population. Vaccine protection declined by mid-August 2021, decreasing from 91.9% in March to 53.9% (p<0.01, n=619,755). Declines were greatest for the Janssen vaccine followed by Pfizer–BioNTech and Moderna. Patterns of breakthrough infection over time were consistent by age, despite rolling vaccine eligibility, implicating the Delta variant as the primary determinant of infection. Findings support continued efforts to increase vaccination and an immediate, national return to additional layers of protection against infection.
