evidence: The WHO Strategic Advisory Group of Experts on Immunization (SAGE) has issued updated interim recommendations for the use of the Moderna COVID-19 (mRNA-1273) vaccine against COVID-19. This article provides a summary of those interim recommendations; you may access the full guidance document here. [...] Individuals who developed myocarditis or pericarditis following the first dose of mRNA-1273 vaccine should not receive additional doses of any COVID vaccine unless with the recommendation of their doctor or a healthcare professional. [...] The Global Advisory Committee on Vaccine Safety, a group of experts that provides independent and authoritative guidance to the WHO on the topic of safe vaccine use, receives and assesses reports of suspected safety events of potentially international impact. In October 2021, the GACVS COVID-19 subcommittee concluded that the mRNA COVID-19 vaccines have clear benefits in all age groups in reducing hospitalizations and deaths due to COVID-19.
