Not sure how good the covid vaccine was. Here's a story you've never heard- I was on a bike ride, January 2019 before there was any vaccine for it, let alone available to persons 65 and older. Covid was already in the news but hadn't hit us yet. Stories where about people getting it in Italy as I remember, cuz Chinese vacation there. At that time the US was already, under Trump, closed to Chinese vacationers. I did a bike ride where I saw a guy with a bike at my turnaround that had offloaded his bike and was getting ready for the ride. It was a steel Bianchi with gold around the top of the seat tube that was fairly unique and memorable but otherwise the traditional Bianchi colors. Nice triple and I had liked it and I dropped by and commented on it... so, we rode rode a ways back, me on my return and him beginning his ride. Turned out he was an airplane pilot that flew a regular milk run from China to Anchorage. So, he was probably one of the first US citizens that was exposed to covid and got it, in China, and as he was recovering from it in a hospital, they didn't know what it was – actually before 2019. At the time we were talking about it, covid was already in the news cuz people in Italy were coming down with it because Chinese vacationers went there and brought it with them. So as you can imagine, with all the news, and what I knew about it, when the vaccine was available (I took Moderna) to those 65 and older I definitely was in line to get it and took every one that was recommended – four in all – and still got covid! So, that is why I passed on getting the covid shot this year.
