There are about one billion red blood cells in two or three drops of blood.
It depends on the type of vaccine. Those made from 'killed / inactivated / recombinant' material generally do not affect eligibility. These include diphtheria, influenza (flu), hepatitis A, meningococcus, pertussis (whooping cough), pneumococcus, Q fever, tetanus, human papillomavirus (Gardasil) and others.
The exception is hepatitis B. If you have received this vaccine, you should not donate for a week as it may interfere with our testing.
Vaccines made from 'live / attenuated' material restrict our use of your donation. We can use the plasma from your donation but are not able to use red cells from a whole blood donation during the 4 week period after vaccination. These include BCG (tuberculosis), measles, mumps, Polio - Sabin oral polio vaccine, and varicella (chicken pox); but 8 weeks after rubella (German measles) vaccine and combined measles, mumps and rubella (MMR) vaccine.
If you are unsure about your eligibility to donate after vaccination, please call your local Donor Centre or call 0800 GIVE BLOOD (0800 448 325) and ask to speak with a nurse.
You should wait one week after receiving this vaccine to donate. Hepatitis A is a quite different vaccine and it is possible to give blood immediately providing you are well and any inflammation at the injection site has settled.
We ask you to wait for 4 weeks after injection treatment and until fully recovered.
We ask you to wait for 2 weeks until the wound is healed and you are fully recovered.
