Image A man receiving the Johnson & Johnson coronavirus vaccine in the Bronx earlier this year. The decision adopted a recommendation by an expert panel that effectively discouraged vaccine providers and adults from using Johnson & Johnson’s shot. Dozens of countries have authorized Johnson & Johnson’s vaccine and have been using it as part of their immunization campaigns.

Evidence has increasingly shown that one dose of Johnson & Johnson’s shot offers much less protection against infection than other vaccines.
