I don't have a problem with them getting him vaccinated, I just feel they are doing it only because it would be more of a inconvenience not to get him vaccinated an would make more work for them to get him to travel, I mean these are the parents that feed him on a bland tit diet an can't be bothered to go get him blueberries at a blueberry festival, couldn't get his hair cut when it was clear he was uncomfortable cause they wanted that stupid disney first cut, allowed him to burn himself because talking to the camera is more important an left him in a van with strangers at the side of a road even though they are aware he's had actual death threats about being snatched from themOf all the things to rip on the Trackers for, getting their kid a third COVID vaccine shouldn't even be on the radar. Yes, there will be kids with health issues in the future, but not from the vaccine.
Also, a person shouldn't avoid getting vaccinated because they are healthy, unless they aren't interested in remaining so. That's the whole point - to avoid the virus and the damage it can do. Vaccines not only save lives, they reduce the chances of long-term health issues resulting from an infection (even mild cases).
(Put me on ignore if you wish, but I feel strongly we need to stop with the anti-vaccine talk already. It's dangerous).
I honestly think if it didn't inconvenience them with trips then they would be like ohhh we will get round to that eventually an it would months later before they could be bothered since its clear they can't be bothered actually going out their way for the kid with anything else
