If it were only so simple.
Young kids can’t yet get the vaccine. I know they seem to get through the disease better, but they can die from it too. Also: other parts of the world still don’t have much vaccine available to them. As long as there are populations that continue to harbor the virus, it will continue to mutate, doing so frequently. Such mutations are usually harmless and meaningless to us humans. But sometimes a mutation makes the virus worse for us. It could make it worse for the young kids, and a mutation could possibly nullify the benefits of the vaccine altogether. We are not out of the woods yet. We all need to be in this together. Everyone needs to get vaccinated, for everyone’s sake.
I agree. The mutations are what are otherwise known as 'evolution'. All living organisms mutate. Most mutations do not convey a survival advantage, so they do not reproduce for long before they cease to exist. Some mutate and are neither better nor worse than the original, so they just continue alongside the original for however long. Some few manage to evade something that would otherwise kill them. They then tend to succeed.
This is why we have weeds today that eat the most powerful weed-killers. This is why we have 'super bugs' that are immune to nearly all antibiotics.
Some of the things we do as a species can make the conditions for successful mutations that will kill us more likely. This is generically true, it's not just about any particular virus or illness. For example, when multiple innoculations are required, only getting one and stopping there, or stopping treatment before the illness has run its course. This is why when you get an infection and the doctor gives you antibiotics, they tell you to take ALL of them, don't just stop when you feel better. Failing to completely eradicate whatever it is that you're infected with allows mutations that have even a slight advantage to keep reproducing, and favor those that can evade, even partially, the treatment being used. People who don't take all their medication are a BIG reason why diseases develop immunity to the medications we use.
The other reason mutations continue to mutate and succeed is because we do not practice the methods that might cause them to die in the person they infect. If a person has a disease, even if they are not aware of it, or only mildly ill, and they do not practice distancing and/or masking, whatever mutations they have won't stop with them if they find another host or hosts.
I have a neighbor next door. He's a great guy, he's been a huge help to me since we moved in to the neighborhood. Friendly guy, would give you the shirt off his back. He is my age, he's got diabetes like me. He lives with his wife and adult daughter. They were really struggling to find a place to get their vaccinations a month ago when I got mine. I told them how to work within the system to get signed up for a vaccination. The wife did it and got vaccinated. The husband and daughter decided to wait until the vaccines became more easily available. They got infected. He got VERY VERY sick and was nearly taken to the hospital. Said he could not move off the couch for a week. Chest hurt, problems breathing, the whole thing.
Now, two weeks later, he feels better. This weekend, they are having a huge garage sale. No masks, and of course he's out meeting people who come by for the sale. Super spreader, I'd say. Not only will he be exposing everyone who visits to what he had, if he has any mutations that would make it harder to vaccinate, he'll be spreading that too.
I don't get it. It's like we want to go extinct as a species.
