I’ll tell you why it’s not great: it doesn’t interop with other vaccination passport. I got vaccinated in the US and I’m in France now and my vaccination is worth nothing. Perhaps it will be a good thing for the short term and to incentivize people to get vaccinated, but I’m not sure what other purpose this really has.
There is an actual procedure for getting your vaccine internationally recognized. I looked this up for tourists coming to Croatia (who do not need to do this). It is conceptually the same as getting documents in your home country legalized for use in the respective country you are going to live in, abroad. I have went through this process more than a few times now. But, it is a pain to do.
1. Get your official vaccine record from your /state/ (not county) department of health.
2. Get your official vaccine record apostilled (certified for international use) by mailing it in (and paying a $10-15 fee) to your state secretary of state (in the state where it was issued).
3. (sometimes required--call a consulate) Get an official translation of the vaccine record (usually a translation on the apostille is not required) from a court approved translator in the country abroad (i.e. France). Typically this costs $35-50.
4. (sometimes required--call a consulate) Get all of this authenticated for use in the country you are staying in, abroad, usually via an official working for the Ministry of Foreign Affairs (i.e. France). This probably costs around $20.
Anyways, this is a lot of work, but this is the legalization process for foreign documents, so that they are viewed as official and usable abroad. Anyways, this is the standard and typical certification process for Croatia, an EU country.
