Vaccine efficacy counters need for booster shots, says Lancet review
The Hindu
Will impact acceptance of vaccines which offer good immunity against Delta and Alpha variants, say authors
An expert review published in medical journal, The Lancet, has recommended that booster doses for the general population are not appropriate at this stage of the COVID-19 pandemic, weighing in on the global debate that calls for caution in administering booster doses. An international group of scientists, including those at the World Health Organisation and the U.S. Food and Drug Administration agency, concluded that even for the Delta variant, vaccine efficacy against severe COVID is so high that at this stage that boosters would not be appropriate and not required. The review summarises the currently available evidence from studies published in peer-reviewed journals and pre-print servers. “The message that boosting might soon be needed, if not justified by robust data and analysis, could adversely affect confidence in vaccines and undermine messaging about the value of primary vaccination,” the paper states.More Related News
