Does anyone know if it ist safe to donate blood shortly before getting the covid vaccine? Will it make you more susceptible to having a bad reaction to the vaccine?

I've been searching without success to find the answer to this. Every web hit I've found has been about donating blood AFTER getting the vaccine.

All it is is a blood donation. No biggie. Eat and drink and go get vaccinated!

Ask the blood tech where you donate.

I wouldn't think it would be a problem for most people.

It might be a problem in that one is required to report any illness right after donation because that illness might have been present in the blood that was donated. For example say you came down with a fever a day or two after the vaccination then you are assuming that it was due to the vaccine but can one be sure that that is the case? If it were a virus or COVID itself that caused that fever then that would bring into question the safety of that donated blood.

It is common for hospitals to be contacted by blood banks asking for units of blood to be recalled and sent back because of reported illness or diagnosed infections in the donors.

You need to contact the blood bank you donate at in order to be familiar to the policies and procedures about post donation signs, symptoms or diagnosed conditions.

I would assume you would be in a worse position to mount an immune response. You would have just lost a ton of white blood cells that your body would have to make. They are made from plasma cells that also make antibodies. Why put your body at a disadvantage.

I agree that it isn't an issue from that point of view. The plasma cells do not circulate in your peripheral blood and are not normal when seen in such blood sampling.

There would be some concerns if blood tests were taken a day or two after a vaccine which can show a slight elevated white cell count but again those cells are not plasma cells.

There would also be concern with regards to receiving a blood transfusion and then receiving a vaccine. Such events can decrease immune responses as immunomodulation can occur and possible decrease the vaccines effectiveness.

I get a monthly infusion of 5.2 liters of Octogam. That is actually the gamma globulin from a whole mess of people. Design to flood out my own gamma globulin. Takes 4 days.

I have decided that I will not get my second shot until the week after the IVIG. Do not believe anyone would have any idea of what would happen if you got the two close together. The old rule...never be a pioneer...
