Should I wait to donate blood if I have received a vaccination?

You may donate blood if you were vaccinated for influenza, tetanus or meningitis, providing you are symptom-free and fever-free. This includes the Tdap vaccine. You may donate blood if you received an HPV Vaccine, for example, Gardasil.
 The list below shows the wait times for donating blood after receiving a vaccination:
- Wait 4 weeks after immunizations for German Measles (Rubella), MMR (Measles, Mumps and Rubella), Chicken Pox and Shingles.
- Wait 2 weeks after immunizations for Red Measles (Rubeola), Mumps, Polio (by mouth), and Yellow Fever vaccine.
- Wait 21 days after immunization for hepatitis B as long as you are not given the immunization for exposure to hepatitis
- Wait 8 weeks (56 days) from the date of having a smallpox vaccination as long as you have had no complications. Complications may include skin reactions beyond the vaccination site or general illness related to the vaccination.
Guidelines on eligibility to give blood change from time to time. The most up-to-date eligibility information can be obtained by contacting the American Red Cross blood center nearest you.

The liquid part of our blood, called plasma, is key for maintaining blood pressure and supplying critical proteins for blood clotting, immunity and maintaining the correct pH balance in our body -- critical to cell function. Plasma also carries the solid part of our blood -- white blood cells, which work to destroy viruses and bacteria; red blood cells, which carry oxygen through the body; and platelets, which help clotting.
