If you have a collection of conference badges from the Before Times, it’s time to dig them out. Like a video game where an item from the first level suddenly comes in handy in the final dungeon, it turns out that the card you’re typically given with a COVID vaccine is the perfect size to fit in a standard badge holder.
We’ve previously suggested laminating your vaccine card (Staples and Office Depot will both do it for free) but that’s no help in-between your first and second dose. Some people are also reluctant to laminate their card in case they’ll have to add a booster dose later. But if you use a badge holder, you can slip it in and out as needed.
Why a badge holder? The vaccine cards are 4 inches wide by 3 inches tall, and that happens to be one of the standard sizes for conference badges. If you don’t have one, you can get a pack of clear holders in that size, with or without a lanyard, at office supply stores or online. In fact, if you search “vaccine card protector” on an online store like Amazon, you’ll turn up tons of repurposed badge holders.
Before you buy, measure your card to be sure: 4″x3″ is a typical size, but there’s nothing stopping a clinic from printing out cards in whatever size is convenient for them. Conference badge holders also vary in size, so this isn’t a universal match. Just a serendipitously common one.
