    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.
