Issues with giving blood? Flu shot...covid etc

[idoitforthepong]

I would like to give blood as they are in need due to covid-19. I know they (most clinics) ask you don't give 6 weeks out or whatever it is...which is a pretty silly requirement and basically puts lab rats out of giving blood ever, but how long after would it effect screening results? they say two weeks for most to replenish level in your body but are there any other complications giving blood can have that would show up at screening? thanks.

PS. I asked about flue shot earlier and I had one a week before screening and had no issues with screening. Silly they ask us not to have those either (for most studies), it's our bodies and our health at stake...let along the health of others in the trial and general public...as we are reminded constantly of lately of course.

More P.S. Any word of trials for Covid-19 besides near Seattle and in London (UK citizens only)? thanks

Some requirements are silly.
On the other hand, us rats may not really know.
Participating in a clinical trial is in the greatest sense, an all out effort. Rats have to put aside other things. One could say that avoiding inoculations that are otherwise beneficial is a sacrifice and so is not giving blood (for money or maybe because you feel altruistic about it).

I spent some time in the military and had to adhere to "silly" rules that seemed useless.
But those are protocols to serve military purposes.

Clinical trials are such that certain other things that rats do have to be postponed or omitted. It is a choice. It is a request of clinical trials that rats forsake other things that involve their health. and of course after a rat screens s/he may not still be chosen for the trial.

Lab Rats as a consensus are not the most intelligent and responsibly-behaved types of people considering that what they do tampers with a study they are, or will be, involved in even though they may think they are outsmarting the clinic and actually doing what they want to do rather than what the study requires.

I had to do a study in which I was not to have gotten the Covid 19 vaccine.
One could say that such a requirement is forbidding a volunteer from taking care of his or her own health just so as to instead participate in a controlled study.
But that is what it is. Studies have such requirements for the sake of controlling certain things within the research study. and lab rats being "hired" to take part have a responsibility . They cannot just have a big sense of entitlement about it.
They are required to do their part.
I know it is no comparison, but some studies forbid eating healthier kinds of food such as broccoli, kale, mustard greens, etc.

The fact that research facilities often keep volunteers crowded in one room or small building is really the ironic issue.

I must admit I was not at all considering the Covid vaccine as I think there isn't enough information about the "cons" about it and there seems to be too many "pro" arguments for it that seem to be over embellished and it seems to me that "Health authorities" are just emphasizing the vaccine so as to take the "best possible" course against Covid because nothing else better exists. In a way that is understandable too but we don't know how many vaccinated people are going to suddenly drop dead 5 years from now "without explanation" and who knows, there may be many children born with deformities from moms who got vaccinated.

But as far as complications coming up in a screening after donating blood (when one was not supposed to donate blood) it can depend. I 'm no official expert but it seems that one major reason why blood donation is not allowed a certain amount of time before screening for or participating in a study is because the volunteer may feel weak and may not be able to tolerate blood draws. The volunteer may be losing a lot of blood within a relatively short time frame. The clinics don't want to take chances and thus have "silly" rules.
Another reason, again I am not an expert, is that it may be noticeable in the "chemistry" of the blood that the volunteer has "lost blood" a short time previously.
"Secretly" donating blood before doing a study in which the volunteer is not supposed to have done so could result in the volunteer becoming sick while in the study and it could be hard for the research staff to determine if it is due to the experimental medication or not.
