Abstract

A look at variant-specific boosters The evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern (VOCs) has raised the question of whether current COVID-19 vaccines protect against VOCs and if a variant specific vaccine may be needed. Of the currently identified VOCs, the Delta variant is believed to be the most transmissible, whereas the Beta variant appears to be the most vaccine resistant. Corbett et al . looked at the effect of vaccine boosting using either the original WA-1 strain vaccine or a Beta variant–specific booster. Around 6 months after the primary two-dose vaccine series, a third boost vaccination resulted in higher neutralizing antibody levels against VOCs in nonhuman primates. Regardless of whether the boost was from the original vaccine or the Beta-specific version, similar increases in neutralizing antibody levels were observed and resulted in enhanced viral protection. —PNK
