Since my last post in August, there have been interesting developments. After receiving advice from my family doctor NOT to get the second Shingrix shot, I asked my son, an MD-PhD neuropathologist, whether he agreed, and he didn't. Confused by this conflict in opinion, sometime in the early fall I asked my doctor for a referral to a specialist in infectious diseases, and was set up for an appointment at a top Columbus, Ohio hospital in mid-December. But well before setting up this appointment, I had done a routine check of my other vaccinations and, discovering my DTaP vaccine was close to needing renewal, had scheduled a renewal shot for early December at my local health department. As I arrived for my DTaP shot, the nurse and I had a cursory exchange of information, but neither of us verified which shot I was getting. As it turned out, the nurse in perusing my chart, had seen I had had the first but not the second Shingrix shot and assumed that was why I had come in. It was only after she had administered the second Shingrix, that I realized I had been given it and not the DTaP. I braced myself for a bad reaction, but not only did that not materialize, but I didn't even have a sore arm. With more than a month having elapsed since then, I have not experienced any negative affect from the shot. Perhaps, it was suggested by another nurse at the health department, the first shot had protected me.
