Can you donate blood after a rabies vaccine?
It depends on why you got it. A preventive rabies vaccine with no exposure generally does not defer you. If it was given after a bite or exposure to a possibly rabid animal, you typically wait 12 months.
The rabies vaccine contains inactivated virus. The wait before donating depends on the reason you received it.
Pre-exposure vaccination (preventive)
This is for veterinarians, animal workers, some travelers and others who have not been exposed. In general, this does not defer you from donating, as long as you feel well.
Post-exposure vaccination
If you got the vaccine after a bite, scratch or contact with an animal that might have rabies, the usual deferral is 12 months. The reason is not the vaccine, but the theoretical risk that you were exposed to the virus.
Rabies immune globulin
Treatment that includes rabies immune globulin after an exposure carries the same 12 month wait.
Quick summary (typical)
- Preventive vaccine, no exposure: generally no deferral
- Vaccine after contact with a possibly rabid animal: about 12 months
- Rabies immune globulin after exposure: about 12 months
Blood centers apply FDA rules and their own policies, so confirm with yours. Tell the screener the date and reason for your vaccine.
This information is general and does not replace advice from a health professional. Your eligibility is always decided at the donor screening on the day of donation. Rules change, so confirm with the American Red Cross or the blood center where you plan to donate.
