airborne viruses that can travel for hundreds, perhaps even thousands of miles

Airborne viruses usually travel about two metres (hence the two metre social distancing rules for Covid-19). Even if a single virus somehow travels farther - perhaps by hitching a ride on a vehicle - it is unlikely to cause a successful infection, because you need enough of them (‘viral load’) to overwhelm host defences.

I don’t know what ‘diluted toxins’ has to do with viruses and immunology since toxins are a rather different matter entirely

Vaccines work in different ways. The oldest method is what you described - attenuated viruses. Newer ones usually do not contain active viruses. They either have inactivated viruses, or, increasingly, just the viral proteins or mRNA. This reduces the risk of the vaccine causing harm to the recipient.

the immune system can ‘learn’ and ‘evolve’ over the course of a single human’s lifetime

If the person survives, their immune system may learn to identify and defend against that virus. Or it might just forget. Or it might cause random damage due to cytokine storms. Or it might forget all previous information. And in any case, some percentage of the population will die.

Thinking that infections are good because they will help increase immunity is like thinking that a country constantly being at war is good because then they’ll always be ready for war. Particularly when you can give the same immunity at a fraction of the risk using vaccines that just have some proteins or mRNA.

allegedly killing a noble

breathe contaminated air in the general vicinity of animals, drink water they’ve pissed or shit in, etc.

Don’t go near animals. Boil water before drinking. Simple as.

That is in fact how a vaccine/our immune system works, yes.

Vaccines work using either diluted toxins, or increasingly, proteins / RNA that just look somewhat like the real thing. The immune system works by enough of the population dying off until only those with the necessary mutations are left.

cows don’t stop existing just because we don’t eat beef.

Humans need to go close to the infected animal to get infected.

being around/eating animals all the time also builds up your immune system’s defenses against diseases that originate in those animals

Oh, so being exposed to new viruses reduces the risk of dying to a virus you got … because you were exposed to it?

Socialism is when the Prime Minister (?, I don’t know what his official title is) serves for life and his son becomes the next PM?

People getting killed is obviously bad. But just to put this into perspective, how many people were killed in Gaza today? How many children? And yesterday, and the day before? Oh wait, we don’t even have a full count because the monsters also murder journalists.

Well, that depends on what you want. Lemmy.world leans right and harbours transphobes and racists, hence the nazi.world jokes. Personally I think such users should just be allowed to make fools of themselves, but if you find that disturbing you can join another instance. lemmy.ml leans left, lemm.ee is fairly centrist, and sh.itjust.works is mildly right. But all are great instances.

You are an amazing person, but I find it funny how in the US even the communists have guns.
