Here's a message that a forum member very recently posted on the Moto Guzzi forum that provides some additional info re shingles vaccinations.

There is a new shingles vaccine that is given in two shots and is recommended even if you had the previous vaccine.....which weakens over time.
I experienced it back in 2014 and warned many on this site the living hell I went thru for 5 weeks..... you do not want to get it! If your insurance does not cover it, the old shot was $200 at Costco. I will be checking with them next week what the two shot package will cost. You do not need to be a member to use the pharmacy.
