Study Notes
- A study by Israeli researchers suggests that vaccinated individuals have a higher risk of getting infected with the South African COVID-19 variant than unvaccinated individuals.
- Pfizer had previously advertised the strong efficacy of its vaccine.
- There are still many uncertainties in the fight against coronavirus, particularly with the emergence of the British and South African variants.
- Laboratory studies had already hinted that the South African variant could break through the protection of the Pfizer vaccine, but the study on real subjects confirmed this.
- The study was conducted by the University of Tel Aviv in collaboration with Clalit, the largest Israeli health fund.
- 400 vaccinated individuals who tested positive for COVID-19 were compared to 400 unvaccinated individuals who also contracted the virus.
- The South African variant has a higher likelihood of breaking through the vaccine's protection, even after two doses have been administered.
- The prevalence of the South African variant is eight times higher in vaccinated individuals compared to unvaccinated individuals.
- The study's results are limited due to the rarity of the South African variant in Israel.
- The study was not intended to derive a general efficacy of the vaccine against any variant as it only examined individuals who had already tested positive for COVID-19.
