I got my first (Pfizer) shot back in mid-may. It gave me a sore arm for 2-3 days. I think I took a pre-emptive Tylenol and went to bed early the first day, but otherwise felt fine. Second shot a few weeks later, barely even got a sore arm. Both of my shots were administered at a local vaccination station set up at the fairgrounds, and the nurses (who each had decades of experience) were so skilled I almost didn't feel the needle at all. I was expecting more of a reaction, but they told me that this is the first vaccine where people have been complaining of LACK of side effects, like we have to get a little sick to "earn" our immunity. People are silly.
As an American, we got a head-start on vaccine access that ramped up more quickly than I expected. A national rollout is no small feat, and it seemed like the previous administration's plan was to leave it mostly to the individual states to manage their vaccination efforts, so I thought we'd be staggering and stumbling through providing doses to the people. Despite not being an "essential worker" or in any "at-risk" group, I got mine about 2-3 months earlier than I had predicted when the vaccines were first announced, which makes me feel both grateful and privileged. It's embarrassing how many of my countrymen have snubbed the vaccine due to all the misconceptions about it, and locked us into continued lockdowns and mandates. Despite our supposed wealth and power and access to information and medicine, we seem to have learned little in the past century; America's death toll has now surpassed that of the 1918 Spanish Flu pandemic (now fueled almost wholly by unvaccinated patients), while the rest of the world is faring considerably better despite delayed access to vaccines. This, I believe, is the cost of making public health a politically divisive subject.
It'll probably be a little while, but I'll take the booster when it's available to me, as I expect covid to become an endemic disease that will never fully "burn through" the population. I've had enough friends who have had it to know that I don't want it, not to mention friends in the medical field with first-hand experience of the worst of things. I'll continue to protect myself and others as best I can while it's still surging through the community.
