As of July 2022, there have been over 575 million confirmed cases of COVID-19 and over 6.3 million COVID-19–related deaths worldwide according to the World Health Organization. However, the actual number of COVID-19–related deaths may be closer to 15 million at the end of 2021. Vaccination against 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 12 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 were 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.
