The Centers for Disease Control and Prevention is sticking with its current classifications: If you've completed your primary series of covid vaccinations, you're considered "fully vaccinated." If you've had a booster shot, you're "up to date."

How long does the COVID vaccine last? Studies suggest COVID vaccines are most effective in the first few months following your shot. That's why when health experts recommend boosters or updated doses, they're usually given three to four months after your last COVID shot.

If you have had your primary vaccination course and you're aged: 75 years or older, you're recommended further doses of COVID-19 vaccine every 6 months. 18 – 74 years with severe immunocompromise, you're recommended further doses of COVID-19 vaccine every 12 months.
