>>There are no clear answers on whether or not you should laminate your COVID-19 Vaccination Record Card.

Look at your card. Notice that there are more slots for additional vaccinations to be recorded? Gotta wonder how that's going to work if you present a laminated card when you go in for a booster (looking more certain every week).

There are protective plastic sleeves available for your card. The 4"x3" fit mine just fine.

Oh, and thanks for the pointer to YesVax.
