If you can get re-infected with CV19 because there’s no immunity after, why will a vaccine work?

I don’t understand this.
People here keep writing things like “even though you’ve already had it, you can still get it again because there is no immunity to it, and it gets worse and worse with each successive case of infection”. Ok, I’m not a scientist or medical person, so I don’t know much about this stuff. But I’ve read that over and over many’s times on this forum, and I don’t understand. And who are all these people who’ve been repeatedly infected over and over many times just since January that we’d already know about successive cases getting worse each time? Are there really that many people getting covid over and over? And if you don’t make an immunity to it after having it, then what is a vaccine supposed to do? How does the vaccine do something that our own immune system can’t do? How’s it possible to be vaccinated and therefore be immune, but having the virus and the. recovering doesn’t make you immune? Can someone please explain this in lay person’s terms? Because it makes no sense at all to me. |

I am interested too. I got COVID in March and it took me several months to not have symptoms. I was left with damage to my heart and so now I am dealing with that.
Very thankful that I survived without going to the hospital but I am extra cautious now about COVID. Also, the precautions that my family and I took - masking, quarantining at home, UV lights in the HVAC - all of it worked and my family did not catch it from me. So keep using the masks. They work. |

| The reinfection rates are very low, so are the people whom the vaccine won’t work on. Nothing is perfect in medicine |

| Most people do get long term immunity from COVID. Reinfection is rare, and it's not clear if these are true reinfections or that the virus was hiding in the body and then flared up again. |

That’s not what I keep reading here. People keep posting that you can re-infected almost immediately, and that it gets worse each time. So who’s lying here? All of them? Or you? This is very frustrating. |

Wrong. I got COVID. Now I am negative on the antibody test 5 months later. My friend got it twice. So, no. We are not even getting short term immunity from COVID. And the disease is not that old that we can say that there is long term immunity. |

There are very few documented cases of people getting reinfected with COVID. Of course, since it can happen, it will happen- there's been 55 million cases after all.
Why can it happen? A mild infection may not lead to a strong, long-term immune response. Or, perhaps your immune system doesn't act entirely normally. Or perhaps you were just unlucky. Your intuition would be mostly right if it were true that your immune system couldn't clear a COVID infection and get a long-term immune response. But it can. Not in everyone, but in most people. Furthermore, vaccines can generally lead to immune responses similar to that of severe infections. Other vaccines don't work on every single person. The 95% efficacy they're finding with these COVID vaccines is actually quite high. |

Are you going to trust laypersons on an anonymous forum, or medical experts? |

At this point I don’t trust anyone. Why do you? |

See? This is what I’m talking about. How is a vaccine going to work then? It makes no sense. |

But surely you’ve read that it’s T-cells that provide immunity? |

The immune response from the vaccine starts out as much higher than someone who had COVID, but will drop off eventually - 6 months to a year. So most likely people will need to be re vaccinated. It just haven’t been discussing that yet.
Also if enough people can get vaccinated, we can contain the virus before the immune response from the vaccine drops making infection much more difficult |

Why don’t you do some research. |

| Reinfection is extremely rare. Less than 1 percent. So the vaccine is still going to be extremely beneficial. |

What you’re describing sounds an awful lot like “herd immunity”. I thought that was bogus. |
