LA Times: Why are COVID-19 booster shots needed anyway?
Many vaccines require booster shots within years (or even within months) in order to maintain high immunity against diseases. Studies have shown that effectiveness of the vaccine against COVID-19 has been declining as time passes, thus the main COVID-19 vaccines within the U.S.–Pfizer, Moderna, and J&J–are currently seeking approval for a third booster shot in order to stay ahead of the virus and maintain high immunity against COVID-19. This booster shot is recommended to be 8 months apart from your first vaccination, but is currently being studied for 6 months.
