How effective is the first COVID-19 vaccine injection without getting the second one?


It is important to have both doses of the vaccine to give you the best protection. The first dose of the COVID-19 vaccine should provide high short-term protection against severe disease for a duration of around 12 weeks while the second dose gives a more durable and longer protection against COVID-19. It can be assumed that protection from the first dose will wane in the medium term, and the second dose will still be required to provide more longer lasting protection.
