"Americans will now have access to updated COVID booster shots after the Centers for Disease Control and Prevention signed off on reformulated versions of the Moderna and Pfizer-BioNTech COVID-19 vaccines Thursday night."

My tour is coming up in 3 weeks, and I do have four Pfizer shots under my belt, so to speak. Latest one was in May. Do I have to get this new 5th one in order to join my tour, or am I good to go?
I emailed the Rick Steves office about this but haven't heard back yet. I know they are very busy. But they did reply to my other emails about museums. It's possible that they are unsure about this.
