The covid vaccines and booster for me resulted in minor inflammation that went away within 3 days. I had fever and chills for the first Moderna shot but just a bit tired for later vaccines and boosters. I have a few autoimmune diseases and suspect my covid hit wouldn't have been as bad if I hadn't been glutened the same day as covid exposure. I know that there is a very minor risk of reaction to the covid vaccines, including increased blood viscosity. I've had two friends die of heart attack/myocarditis after getting covid, and two others with heart damage. I wonder if some of the blood clotting risk could be minimized by taking aspirin or other blood thinner when getting covid or vaxxed/boosted? CDC, NIH, and Nature all have online risk/benefit analyses of getting vaccinated/reactions. Unfortunately, most people don't know how science works (I was a research scientist) and this combined with miscommunication/misinformation has resulted in some distrust of science. The distrust started a few decades ago with climate science politicization. Or actually, centuries ago when scientists reported things people don't want to hear.
