Vaccinations are mandatory for travellers to (or from) countries where certain diseases are endemic (eg yellow fever).
- Vaccinations are mandatory or recommended for people in certain occupations
- This is indicated by a certificate of vaccination

Will we need a to show a certificate of COVID vaccination before we travel internationally, or take certain activities?
- What form of certificate would be most widely recognized?
- Will there be an App for that?

A brilliant idea. Preferably a bar coded card that can be referenced to source and date of vaccination. Apps are all very well for people who need an electronic life substitute, but my phone just makes calls and texts.

Bus and taxi drivers would do well to check your vax card before letting you in to their fertile public environment, and an annual check on schoolkids might prevent a resurgence.
