‘In an expert review published September 13 online in the peer-reviewed journal The Lancet, a group of US and international scientists claim current evidence does not support providing booster doses of SARS-CoV-2 vaccines to the general public. The group—including 2 departing US FDA officials and WHO experts—said that any decision to provide additional vaccine doses should be evidence-based, concluding that despite a small drop in protection against symptomatic disease caused by the Delta variant, authorized vaccine regimens continue to provide high levels of protection against severe disease and hospitalization for all major SARS-CoV-2 variants. The authors acknowledged that some additional doses might be needed immediately for certain elderly and immunocompromised populations, but they encouraged prioritizing primary immunizations over booster shots for the general public.
‘The authors also acknowledged that booster doses might be necessary in the future due to waning immunity or the emergence of a vaccine-resistant variant but that current evidence does not warrant additional doses now because “efficacy against severe disease remains high.” The authors noted that currently available vaccine doses could save more lives and provide better protection against the emergence of new SARS-CoV-2 variants if used in previously unvaccinated populations, especially those in low- and middle-income countries.’
