Pfizer Covid vaccine less effective in South Africa after Omicron cases: Study

India Today  

Pfizer-BioNTech's Covid-19 vaccine has been less effective in South Africa at keeping people infected with the virus out of hospital since the Omicron variant emerged last month, a real-world study published on Tuesday showed. When it came to avoiding infection altogether, the study by South Africa's largest private health insurance administrator, Discovery Health, showed that protection against catching Covid-19 had slumped to 33 per cent from 80 per cent previously. South Africa's daily infections have since risen to more than 20,000, with 35 per cent of tests coming back positive in figures reported on Tuesday, and a further 600 hospital admissions and 24 deaths. "This could be a confounding factor for these hospital admission and severity indicators during this Omicron wave," Ryan Noach, chief executive of Discovery Health, said in a briefing on the study.
