Exposure to someone with COVID‑19 can happen when you least expect it.

The good news is XOCOVA can reduce the risk of COVID‑19 symptoms before they start.

If you were exposed to someone with COVID‑19, XOCOVA can help reduce your risk of symptomatic COVID‑19 if you start taking it right away within 3 days (72 hours) of exposure.
