Nobody should have to justify their eligibility for a Covid vaccine when most everyone was eligible in 2021.
The reason we had eligibility by age initially was because the rollout was just ramping up and early supplies were still limited, so governments prioritized the most vulnerable, who tended to be the most elder.
There should be no age limits on vaccine eligibility. It only exists now because governments don’t want to pay for the doses necessary to cover their general populations.
