Parents used to vax themselves yearly against cold, they did it for more than a decade, and it worked, they never got cold. But then they became anti-vaxxers since the bolsonaro covid years. Now they spend maybe 1/5 of the year suffering of cold. They are old, it takes them time to heal from it, and sometimes it becomes very serious. They can't ignore it, they admit that, but they still won't take the yearly shot. They're probably going to die from cold and I can't even feel bad about it. I think society was less problematic when people died in their 60s and many before that. Now we have a big population of expired retards who have the mentality of children but don't accept to be tutored.
