If you've already had covid-19 and displayed only mild symptoms, can you get it again and die from it?

We do not yet have studies to prove if Covid can be got again.We have some few anecdotal cases of people having it twice. Could be faulty testing and is not considered confirmed. It is "thought" that if you have a severe case your antibody lode is larger than if you have a light case, which may not give you a large number of antibodies in your system. Long story short is we ALL need to get the vaccine unless there's a medical reason we cannot. Especially important now that the morphed virus from So Africa is here already. The more people who GET Covid-19, the more chances the virus has to adapt and be worse.

There have been instances where someone has reportedly been re-infected. With all these new strains being discovered, she could possibly be re-infected by one of those. Experts still advise wearing masks even if you've recovered from COVID and even if you've been vaccinated. We're a long way from being over this pandemic.

Here's what Google says when asked "Can you get Covid19 more than once: As of yet, we are unsure of the nature of human immunity to Coronavirus.

What the 'experts' know is less than what they DON'T know about this virus.

Saying that we still need to wear masks, and now preferably TWO masks, and social distance for the entirety of 2021 even AFTER being vaccinated tells me that your mother is mistaken in her thought process. And if not, who knows? That's the risk she's taking with her thought process.

But then again, in her defense, it's HER life to live as SHE sees fit.

Wearing 2 masks and staying cloistered in one's home for 2 years is not really 'living' anyway, so whatever your mother chooses to do with her life is her prerogative.

Good luck!

There is a "new" variant of the COVID and it seems to be more easily spread.
Just that fact should cause her to take safety measures. Because it is a different strain she could get it again.
Even if she can or could not get it again the reason for HER to take precautions is she needs to protect others that are not immune. While she might not be able to get the same strain again that does not mean she can not GIVE it to someone else. And she could get another strain of the virus.
So tell her if she loves you and your family she will take precautions for YOU if not for herself.
