Addiction is not something you can choose to stop. It might take a very long time until you recover. It will be hard but I
will always be by your side fighting through it. Drugs and addiction can kill you. We must take action now before it’s too late. (Idk what to say lol so sorry if this is bad u should rephrase it or make it better)
The answer is viruses change their form when the immune system knows how to kill it and thats how they trick the immune system and viruses are much smaller than bacterias
Kinda like medicine. Vaccines go into the body and target the virus, some vaccines make the virus weak, some exterminate the virus completely, and some aren’t tested enough to work. However with all the little battles happening to kill the virus you can get sick from vaccines.
