Any recommendations for a neck lanyard for vaccine card?

I haven't seen American cards, but the Canadian ones are only as big as a business card.
Try the Dollar Stores, they often have useful stuff like lanyards with clear cases.

We just returned from 2 weeks in France and we were never asked for our vax card except for our outgoing flight SEA to FRA so you might not need it to be so handy. We carried ours in the money belt.

This looks like a useful item for international travel, keep vaccine card, passport and a couple cards all together.

Clear plastic holder for card, and a lanyard with two ends that clip onto either side. The lanyard is described as a mask holder. The CDC card holder is just that.

Office Depot, Office Max, or a sports team store I.e. Mariners/Seahawks/Sounders. I took apart some of my husband’s lanyards from conferences he’s attended and just used the clear plastic holder. I do have a caution on Amazon - what I ordered from Amazon had the exterior measurements that looked like it would fit, but the plastic seam made the opening too small.

I recommend you forget it, you'll never use it. As of last Friday, the need to show the card in Italy dropped down a level, and will drop down again on May 1. We have been in Italy for 3 weeks and have shown the card once, and the server didn't even look closely enough to see the CDC logo.

Thanks for the replys. Glad to know I probably won’t have to show much. Guess I’ll just keep using a cheap plactic holder. Any problem folding the vaccine card an storing in a slear credit card protector? Still hoping to use my super mini purse that served me well for at least 20 trips.

folding the vaccine card to fit into a credit card holder

Just traveled for a week. Bought a nice case for my passport and vaccination card as well as a lanyard. Only had to show my card a couple times on the first day. No one asked for it after that. Would not recommend the expense.

Ended up getting the Walaufsti Vaccine Card Holder from Amazon, 2 for $13. Came with detachable lanyards. Figure even if I don’t wear, will be a great way to store the vaccine card and ID in purse or backpack. Very pleased with purchase.
