Tartof et al.: Durability of BNT162b2 vaccine against hospital and emergency department admissions due to the omicron and delta variants in a large health system in the USA: a test-negative case–control study

Another study that shows the problem & failure of these vaccines; I do not agree that it works in any manner but: "waning was apparent against SARS-CoV-2 outcomes due to the omicron"

Durability of BNT162b2 vaccine against hospital and emergency department admissions due to the omicron and delta variants in a large health system in the USA: a test-negative case–control study, Tartof, 2022

Key findings for you to consider:

Researchers evaluated the effectiveness and durability of two and three doses of the BNT162b2 (Pfizer–BioNTech) mRNA vaccine against hospital and emergency department admissions due to the delta (B.1.617.2) and omicron variants; a case–control study with a test-negative design, analyzing electronic health records of members of Kaiser Permanente Southern California (KPSC), a large integrated health system in California, USA, from Dec 1, 2021, to Feb 6, 2022; “analyses were done for 11 123 hospital or emergency department admissions. In adjusted analyses, effectiveness of two doses of the BNT162b2 vaccine against the omicron variant was 41% (95% CI 21–55) against hospital admission and 31% (16–43) against emergency department admission at 9 months or longer after the second dose”; researchers also reported that “3 months after receipt of a third dose, waning was apparent against SARS-CoV-2 outcomes due to the omicron variant, including hospital admission”.
