Two jabs of the Pfizer-BioNTech vaccine are 90% effective against COVID-19 hospitalizations for all variants including Delta, for at least 6 months, confirmed a new study published by The Lancet.
The study, conducted by Kaiser Permanete and Pfizer, found that while effectiveness against all SARS-CoV-2 infections declined over the study period, effectiveness against hospitalizations remains at 90% overall for all variants.
“Our study confirms that vaccines are a critical tool for controlling the pandemic and remain highly effective in preventing severe disease and hospitalization, including from the delta and other variants of concern. Protection against infection does decline in the months following a second dose,” said lead author of the study Dr Sara Tartof, of Kaiser Permanente.
The study analyzed 3,436,957 electronic health records from the Kaiser Permanente Southern California (KPSC) health system between 4 December 2020 and 8 August 2021 to assess the effectiveness of the Pfizer vaccine against COVID-19 infections and related hospitalizations.
