In last week’s article ‘CDC gives limited recommendations on COVID-19 boosters,’ we incorrectly stated that Dr. Hamid Merchant’s February 2021 paper in Expert Review of Respiratory Medicine showed that 97 percent of fully vaccinated subjects who died were aged 50 years or older. Dr. Merchant’s published paper showed that prior to the vaccine rollout in the UK, 98 percent of COVID-19-associated deaths were in individuals aged 50 years or above. His finding regarding post-rollout deaths is based on his analysis of more recent Public Health England vaccine surveillance data and has not yet been published.
