Vaccination cards will be issued to everyone getting COVID-19 vaccine, officials say

COVID-19 Vaccination cards will be issued to all Americans that receive the coronavirus vaccine is confirmed. Once the vaccine is distributed beginning in late Dec 2020, American's will be issued a card with their vaccination dates/doses and when they'll need to return (if additional shots are needed). Airlines are already making plans to make this mandatory, once the vaccines are widely available- particularly for long-haul/overseas trips. I'm still active military, so I probably won't have a choice, and will get one probably next year with my annual physical. What does everyone think of mandatory vaccinations in order to fly?
