Mayo Clinic Q and A: COVID-19 vaccine boosters and third doses

DEAR MAYO CLINIC: Both of my parents have been vaccinated for COVID-19. The doctor told my mom she is eligible for a third dose of a COVID-19 vaccine, but my dad is not eligible for a booster now. Can you explain who needs an additional vaccine now, and the differences between a booster and third dose.
