Just to report, on October 1, I got the Moderna vaccine (first shot), and I'm ready to be told that I "cucked out." Lol. So far, I'm not magnetic (which really sucks - I was hoping for that) and do not have an insatiable urge to buy Microsoft products. My arm had some mild pain for a few days, and on the following Tuesday, I got a few cold symptoms (nasal congestion, a little coughing, and a light sore throat) but no fever. They lasted until Saturday. (I'm scheduled to get my second shot on November 5.)
I'm happy both with my decision to wait and my decision to ultimately get it. By waiting, I was able to make a much more informed decision. I was able to avoid Johnson & Johnson and AstraZeneca (which are associated with blood clots). I was also able to get the vaccine that clearly protects best against variants (like Delta), as opposed to Pfizer, which was the early favorite.
I'm also glad that I ultimately chose to get vaccinated. I did consider waiting this out, but the big thing that changed my mind was seeing the Delta spike while I was in Texas. That showed me that this thing is never going away, and obviously as I age (now 45), I'm going to become more and more vulnerable to it. I'd rather vax-up now than wait for a Covid infection to knock me on my *** or worse if I get older. Furthermore, the UK is mostly moving past Covid restrictions based on the assumption that people are getting vaccinated, and their vaccination rate is high. Social distancing is becoming far less enforced, and other than in medical settings, most people are not wearing masks. The system here isn't built to protect the unvaccinated anymore. It's now built to promote immunity (through vaccination and immunity), and the UK is largely moving on.
In all, I think I made the right move.
