Vaccine passports could indicate date of expiration and date of renewal when boosters show full vaccination status as now in Israel. But that’s not really what you are asking?
And …
‘The vaccines were 87 percent effective overall at preventing hospitalization, protection that remained relatively consistent before and after Delta became the country’s dominant variant, the study shows. But that figure masks notable differences between age groups. The shots were only 80 percent effective at keeping adults over 65 from being hospitalized with Covid, while they were 95 percent effective for people between ages 18 and 64.’
is probably explained by the fact that the older people got vaccinated first and therefore their vaccines are older and had more time to wane.
