As of June 2022, there have been 527,211,631 confirmed cases of COVID-19 and 6,289,371 COVID-19–related deaths worldwide according to the World Health Organization (though they recently reported that the actual number of COVID-19–related deaths reached closer to 15 million by the end of 2021). Vaccination against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a critical tool to ending the global pandemic. Several vaccines across multiple platforms have already been rolled out internationally, and more than 11 billion vaccine doses have been administered to date. Global collaboration has aimed to provide safe and effective vaccines that can help reduce the devastating impact of COVID-19 infection. Currently, several Omicron subvariants have emerged that are better able to infect vaccinated individuals than previous SARS-CoV-2 viruses. However, vaccines continue to provide substantial protection against severe illness and death, especially in those who have received one or more booster doses. In the United States, the FDA is continuing to review the parameters of its authorizations for currently available vaccines as well as the merits of re-formulated or alternative vaccines to better address current and future viral variants of concern. For the most current guidance, check the clinical consideration from the Centers for Disease Control and Prevention (CDC).
