For those who are above age 50, I found the Shingles vaccine (two doses, like Moderna/Pfizer) to be SIGNIFICANTLY worse as far as side effects. Felt like my left side had been hit by a car on both first and second dose. I just read that for those of us who received Pfizer, a third booster will likely be required within a year. Hopefully, we'll just be able to walk into a local Walgreens or CVS and get it on the spot.
