All viruses mutate, that's normal. It's just normal variance in a virus. There's nothing to worry about. There is no evidence that any new variant "targets young people more", that's just fear mongering.

Truthfully, I had a virologist discuss this with me and in actuality there is good science behind how variants are in fact likely to be deadlier because lockdowns have weakened our immune systems and thus the weaker viruses haven't been killed off as readily, thus the virus is better able to mutate into viruses that can get around our immune system's defenses. In effect, the virologist said because of lockdowns, social distancing, etc... we will have created a scenario for variants of the virus to develop that will be more deadly. This gets compounded further when you consider the mRNA vaccine as well and how it handles the virus. You can still transmit the virus with the mRNA vaccine so the vaccine also allows for the virus to mutate into variants that will be more deadly.

In short - there's good science behind the variants of covid-19 likely to be more deadly but just how deadly is being blown way out of proportion.

You can check your probability of dying based on historic data at www.qcovid.org and you'll find for someone 32yo who is healthy (me), there's a 0.0005% chance of dying from covid. I am 100x more likely to get struck by lightning. If that increases to 0.001%, that's still entirely irrelevant.
