re boosters, it has been interesting here in italy as i have had to explain that my parents (US, already had booster) are fully vaccinated with the initial two doses as in italy they fixate only on the last dose listed on their CDC cards as when we first arrived their booster was not more than 14 days ago when really they completed both initial doses back in march.

so thats fun.

but not as frustrating as in amsterdam where we had to get tested each day to get a QR code to enter restaurants...or for one scottish couple, arguing with a restaurant host to explain that scotland is indeed part of the UK.
