Some viruses never change. The body can accurately identify them so you have lifetime immunity. One time and done. Measles, chicken pox, these never change.

Influenza has so many variations because it mutates kind of like how we breed dogs. How could a mastiff and a Pomeranian both come from wolves? They were genetically breed. Some viruses mutate rapidly and then actually breed with each other.

If you get one influenza A and B together they might “breed” or cross transfer genetic material to create a who.e new virus.

This is precisely why they never made a vaccine for colds. Coronavirus are cold viruses, they mutate around vaccines eventually, also your immunity so you can catch a cold twice, or dozens of times in your life.

They knew Covid would mutate around the vaccines eventually. They will need to make them yearly like the flu vaccine. There is no lifetime immunity to a cold virus, vaccine or natural immunity.

You do carry some TCell information. Like how the Spanish didn’t get wiped out by smallpox but the Natives did. Spanish had some Tcell immunity but it took hundreds of years passing it down from mom to baby to build up. We are a long way from any kind of lifetime T cell protection. Protection from SARS lasted a few years in some. They think 6 months for average if you get Covid or the vaccine, you might last a year.

I work frontline so I get Covid about every 10-11 months. I’ve had it three times. But I have a low white count and do get sick frequently.
