I just got over covid a few weeks ago. For me it was like having a mild cold.
There are still a lot of people dying every day from Covid.
And while the death rate among those so afflicted is much lower -
that doesn't mean that getting Covid is some kind of picnic.
It was early complacency about Covid and disinfo and misinfo that caused many needless deaths. Such negligence is likely to continue.
Although moreso in some countries than in others.
What caused those unfortunate deaths was because of a new virus. A new virus and no immunity = Deaths. As a virus mutates and people gain immunity the death rate drops. It is not in a viruses best interest to kill its host.
i get the impression your age is about 15.
read about sars.
your statement about a virus mutating is exactly what happened due to so many refusing the vaccinations. look at herd immunity. not the immunity you purport. it seems you are saying that people will eventually become immune as the virus spreads.
