because everything just gets folded into the culture war. but why?

The human mind likes to find patterns and binaries are the simplest pattern. As social creatures we apply this to our interactions because it makes it easier to filter information.

I know some guy that took the booster in a similar way in Europe; he took the first shot in his native country, the second in the country where he lives and works and the third back in his native country 5-6 months later.

That feels like lying and possible stealing that dose from someone that has not been vaccinated yet.

We bought so many doses that we are literally throwing them away! Meanwhile poor people on other continents go without. The admin wants people to have boosters. Are they, the current admin, wrong to push for boosters? The FDA members that have resigned might say so, but what about the old and infirm, and health care workers, who have rapidly waning protection?

The "old and infirm" (65+ or immunocompromised) are already authorized and eligible to receive a third dose booster shot.

And effectively anyone can. AFAIK no one is requiring proof of why you're claiming to be immunocompromised.

US and many Europe countries reached a point where the number of vaccines ordered and delivered is higher than the number of people that wants to take the vaccine. My country donated a few million doses that were in danger to expire.

The politicians in your country also heavily indebted the country further just to buy said vaccines even though ~26% took it and the rest firmly reject it. You would think said politicians would stop with this bs and try tackle actual issues, maybe create more Emergency Rooms or improve the poor state of hospitals.

Which country was that? Pretty much all countries with GDP over 20k USD have reached 60% and higher.

We don’t have an issue in the US with a lack of supply of vaccines
