Having your platelets and plasma collected does not decrease antibody production.
“You should avoid donating blood for the next ten days.” Questioned after the injection of a second dose, a nurse gave rise to fear, while the demand from hospitals for platelets and plasma is present. In the event of a recent vaccination, against Covid-19 for example, should blood donation be avoided?
Head of the Vaud vaccination campaign, Professor Blaise Genton is reassuring: “Donating blood does not weaken the immune response of the messenger RNA vaccine. Rather, the cells that produce the antibodies are in the marrow. And the immune system remembers the possibility of making them when exposed to a pathogen and will produce them when needed. ” The Red Cross allows blood donation two days after coronavirus injections, except in cases of side effects such as fever. As for vaccines against other diseases, she recommends waiting 48 hours for most (tetanus, rabies, mumps), two weeks for hepatitis B, four weeks for yellow fever and cholera, and one year. whole if you have been vaccinated against rabies, tetanus and hepatitis B after being exposed to them.
