Coronavirus booster vaccination provides “solid protection against severe infection with variants of the SARS-CoV-2 virus of the group of concern,” according to a study published by the medical journal The Lancet.
Scientists have already identified several variants of concern for SARS-CoV-2 (VOC) that partially escape serum neutralization induced by current vaccines. Previous studies have also shown that vaccines provide reduced protection against symptomatic infection with SARS-CoV-2 variants.
Australian researchers from the University of New South Wales, University of Sydney and the University of Melbourne conducted a meta-analysis of 24 published laboratory and clinical studies to see if in vitro virus neutralization titers still predict the degree of protection that vaccines provide against infection with SARS-CoV- variants 2. It turned out to be so.
A booster dose significantly increases protection against new variants of the coronavirus
Booster vaccination – the so-called “booster” – against COVID-19 provides “solid protection against severe infection” with variants of the SARS-CoV-2 virus of concern (VOC), at least in the medium term, according to a study published by “The Lancet”.
As further analyzes showed, good protection against the current variants of concern can be achieved by vaccinating with existing vaccines (targeting the spikes of the primary virus variants) and administering another dose of these vaccines, passed.
‘Vaccines targeting the new variants of concern may be needed in the future, but existing vaccines are still an effective method of boosting immunity against the current variants of concern,’ underlined.
