Although we can obviously get pretty upset if we lose our phones or if someone compromises our credit card numbers, there are certain things in our lives that we keep even more closely guarded than those.
Because while it's annoying to get a new phone or cancel a credit card, it can be far more grueling to replace a birth certificate, a passport, or to deal with a compromised social security number. But that care isn't just based on inconvenience, but rather the fact that those documents are important ways for us to prove that we legally exist.
Fortunately, the card somebody gets after receiving a COVID-19 vaccine isn't quite as nightmarish to replace as those documents but there are some good reasons why it's a good idea to treat it with similar care.
