| Real-world Israeli study shows SA variant can break through Pfizer vaccine |
| 2021-04-11 |
| [JPost] - The Pfizer coronavirus vaccine is somewhat less effective against the South African mutation; a new study has shown, raising a red flag among health professionals of the need to continue monitoring Israel’s airports to keep out what could be dangerous mutations. The study, conducted by Clalit Health Services and Tel Aviv University, was the first of its kind based on real-world data. It has been published on the MedRxiv online site and therefore has not yet been peer-reviewed. ...The study seems to counter a report released by Pfizer earlier this month that claimed the vaccine was 100% effective in preventing coronavirus among participants from a trial in South Africa, where the mutation is prevalent. ...Specifically, the researchers examined around 400 members of Clalit Health who tested positive for the virus 14 days or more after receiving the first dose of the vaccine in comparison to 400 unvaccinated people who caught corona, too. The cohorts were matched according to age, sector, gender and more. The study showed that the South African variant is more likely to break through the vaccine’s protective effect, even after two doses have been administered and more than a week has passed. the $$$ quote ...among individuals who had been infected after receiving two doses of the vaccine, the prevalence rate of those who had the South African variant was eight times higher than the rate in the unvaccinated matched individuals. |

| #4 If hospitalization rates don’t rise precipitously due to large numbers of South African mutation patients, then increased positive tests aren't all that important, it seems to me — it just means herd immunity will be reach sooner. |
