Blood test after injection

I always wondered if a blood test after an injection is ok or are they potentially taking out your blood with whatever vaccine or injection you took?

Vaccines and most injections are given IMI (intramuscularly) or SC (subcutaneously), so into muscle or into the layer under the skin. Doing so provides a particular method of release for the substance injected. SC is slower release compared to IMI which is in turn slower than than IV. In the case of a vaccine it designed to provoke a localised response which then stimulates the immune system.

There would be no issue with having blood drawn following a vaccine or injection ngng.

If on the other hand you were having say a Remicade infusion, you would insert the cannula and take blood first then proceed with the infusion. You wouldn’t draw blood from the vein/cannula in which you are infusing a medication.

Thanks Dusty. I had a vaccine and bloods taken soon after and got a little paranoid. Glad that there isn't anything to worry about.
