evidence: Vaccination should not be delayed in anticipation of newer versions of the COVID-19 vaccine. For people at a high risk of getting severe COVID-19, a dose of any available vaccine is more beneficial than delaying vaccination. [...] Billions of people have received the COVID-19 vaccine to date, showing that the benefits of COVID-19 vaccinations outweigh the risks of getting ill with COVID-19. Do not delay COVID-19 vaccination if it is recommended for you by your health care provider. Getting vaccinated could protect you from severe illness and save your life. [...] More serious or long-lasting side effects of COVID-19 vaccines are possible but extremely rare. National health authorities monitor vaccines to detect and respond to rare adverse events. At the regional and global level, WHO also supports countries in monitoring vaccine safety.
