Covid is a virus. It mutates constantly. You can develop an immunity to viral strain A and still catch viral strain B.

Just like the flu. You catch the flu you’ll never get that strain again.

And flu shots? Guesses. They guess that strain whatever will be most prolific in the country so they give shots for that strain. People might get a different strain. It’s like roulette with viruses.

BUT if you have a strong immune system your body can fight Covid off before you get sick AND still develop immunity.

People with the vaxx shots still get sick because it makes their immune systems weaker. So the shot might ostensibly protect them from strain 94b but they get sick from 97a or 89d.

So yeah natural immunity is definitely thing and vaxx shots weaken and damage what you have.

no. not in the immune system sense.

No, not exactly, and not specifically in this case.

Natural Immunity would normally develop in most people after getting infected 4 or 5 times. However, Covid-19 is the most transmissible and fast-adapting/evolving virus in the history of science. This is mostly because it was probably engineered for maximum transmissibility. The problem with Covid is that it was so transmissible that it managed to cross the species barrier, back and forth, dozens of times. We've found lions with Covid (but not bats hilariously).

This means that when your body gets infected with one strain of covid, it can develop natural immunity to one strain. Not the dozens of additional variants. Now, people who've been infected will have an immune system that will recognize the virus and it's spike protein, so you are better off should you survive your initial infection than someone who not infected, or someone who was given the MRNA injection which only manufactured the spike protein. So, your symptoms should be lessened (that's the natural immunity), but the virus evolves so rapidly that it's impossible to stop from being infected.

I tried to warn people at the time: almost every single human being alive in 2020 was going to be infected with Covid. It's effectively impossible to stop, so the only way to inoculate the population would have been through intentional infection of the healthy.

Hilariously, this is where we go back to where the virus evolves quickly. The best reproduction strategy for any virus is to not kill the host. Evolution will actually dictate that viruses will get less lethal with exposure and adaptation, because of the benefits of keeping the host alive. As exposure became more common, the lethality of the virus would go down. This is why quarantines and lockdowns were bad, even form an immunology standpoint, you wanted to spread the infection to lessen it's lethality over time. Keep the vulnerable at home, but allow the healthy to get sick in a safe manner to build up immunity and let the virus evolve to be less deadly.

Contrast this with ebola outbreaks that kill 50% or more of infected. They kill their hosts so quickly that it becomes impossible for the host population to survive the infection. In so doing, the virus routinely exhausts it's spread in humans once an outbreak starts. You basically can't have an ebola pandemic.

I disagree with u/Filo76 because I haven't seen anything to suggest vaccinations make the immune system weaker. This one in particular just gives you a spike protein, which never immunized you from anything, but did send your body into a kind of immunological shock to fight off a bizarre protein strain. That will help your immune system deal with the Spike Protein, but little else. It doesn't prevent infection or transmission, and it was never designed to. The whole point of the genetic therapeutic was for it to help reduce hospitalizations, because people didn't know how lethal remdesivir & respirators were at killing Covid patients.

I get what you're asking. if you get over something you had an immune response, at least for a while. What we're talking about is if the previous exposure has given you enough lasting immunity so that the next time you encounter the virus, your body deals with it before you become sick.

The human body is normally quite resilient to anything thrown its way if you are roughly healthy enough to keep living without impairment. The immune system doesn't need to know what its facing to defeat it, it just will take longer and is much worse on you as its cycles through whatever method it figures out will work.

Antibodies and built up immunity to certain sicknesses is just it specializing in knowing what will work in the future, and doing so fast enough that it doesn't need to reach Fever levels or vomit level coughing because the virus doesn't get deep enough in the first place to warrant such.

Even if it mutates, you'll be much better equipped to handle it and everything else because your immune system got a good work out to strengthen itself.

This is why its important to let kids get sick regularly as they grow. Because without doing so they will grow up incredible brittle and unable to handle the ravages that exist in the world of sickness without the resilience and personal attention a child has. This is one of the reasons why guys like our grandpas could live until 103 drinking whiskey and smoking daily, while the current generations are dying off super early after being raised in increasingly sterile environments.
