‼️JNJ's #coronavirus vaccine's efficacy against moderate/severe #COVID19 was 72% in the US, but only 57% in South Africa where 95% of cases were the B.1.351 variant that's more contagious & has mutations allowing it to evade vaccine-mediated antibodies.

The upside: JNJ's #coronavirus vaccine was 85% effective against severe #COVID19 across all geographies and all variants. That trend increased over time, with ZERO severe cases in the vaccinated group after day 49.
JNJ's #coronavirus vaccine only requires 1 shot - a big advantage over Moderna/Pfizer - and provided 100% protection against death from #COVID19.
Bottom line: it's very good and "works," but will help us fight this virus, especially in lower-risk people.

CONCERNING: the new P1 #coronavirus variant from #Brazil appears to evade naturally acquired immunity.
JNJ's #vaccine appeared less effective against the South African B.1.351 variant–it's likely that it will perform WORSE against the Brazilian variant.🦠

Bottom line: if you have a choice, get the Pfizer or Moderna vaccine, but the JNJ vaccine is still decent. AND even if you get the JNJ one first, you can get a different one (likely updated for new variants) later!💉
