My vaccines are already in the government system. Here we have a password that works for most government accounts. You sign into the "Yo Me Vacuno" site with that and it pulls up the vaccines, you had - brand, location where it was given and date. You can download a certificate with a QR code. I do wonder, though, if there is some sort of requirement for vaccination proof from other countries, how they are going to figure out what is real and what is falsified.
