We all like to make jokes about the evidently neverending COVID vaccine schedule we're all now apparently obliged to follow. And yes, there's something sort of grimly funny about it, in a dark and sad sort of way.

But for real though it's happening:

Waning vaccine immunity and rising infections due to the Delta variant has prompted wealthy nations to reconsider the definition of "fully vaccinated" -- which usually means two Covid-19 jabs.

UK Prime Minister Boris Johnson admitted as much on Monday, saying boosters were vital to prevent pandemic restrictions from being reintroduced. "It's very clear that getting three jabs -- getting your booster -- will become an important fact and it will make life easier for you in all sorts of ways," he told a press conference.

Other European nations are moving towards mandates on booster jabs. By December 15, anyone over the age of 65 will need a third dose to revalidate their vaccination pass in France, President Emmanuel Macron announced last week. In Austria, full vaccination status expires after nine months of the second dose, which in effect enforces booster doses. In Israel, unless you received your second dose of the Covid-19 vaccine within the last six months, you now need a third dose to become eligible for a green pass, which allows entry to gyms, restaurants and other venues.

Real talk though: If, which is supremely likely, leaders are just going to continuously require new shots in order for us to be considered "vaccinated" against COVID-19, how can anyone ever actually be called "fully vaccinated?" What does the term "fully vaccinated" even mean in this context?

This is apparently the world we live in now!
