COVID-19 Booster: Do I Need One If I’ve Already Had COVID?
A very common question we hear is:
“If I’ve already had COVID, do I still need a booster?”
Our advice is yes — because natural immunity fades, and each new variant behaves slightly differently.
How long does natural immunity last?
After COVID infection:
Antibody protection declines over months
Protection against severe disease lasts longer than protection from reinfection
New variants can partially bypass old immunity
This is why reinfections are now common — even in healthy adults.
What does the booster do?
A booster:
Restores waning immunity
Strengthens protection against severe illness
Reduces risk of long COVID
Improves immune memory against newer variants
For higher-risk patients, this can be life-saving protection.
Who should strongly consider a booster?
Boosters are particularly important for people who:
Are over 50
Are immunocompromised
Have respiratory or heart disease
Are carers or healthcare workers
Had COVID more than 6–12 months ago
Can you get the booster too soon after a COVID-19 infection?
Yes — you should wait until:
Acute symptoms have fully settled
You are clinically recovered
The recommended interval has passed (varies by guidance)
A clinician can advise on correct timing.
