    1. The covid antibodies from recovery from illness last at least a few months.

    You should not get the covid vaccine while you have naturally occurring antibodies.

    2.  It depends.

    For most people it's about 3.5 months.  Some people are losing their antibodies at as little as 2 months.  People who have severe cases seem to have antibodies for longer.

    3. No one knows.

    A study in the New England Journal of Medicine from earlier this month said that at day 119, people still had preventative levels of antibodies but the antibodies were decreasing.

    How do we know?  We can test the levels of antibodies with a blood test.

    In response to the Labguy:

    a) you SHOULD NOT get current vaccines when you have preventative levels of IgG & IgM antibodies.

    b) the vaccine is NOT creating any changes to T or B cells, so there is NO memory cells changes. 

    c) we don't know how long immunity lasts naturally or with the vaccines.  We know both groups have re-infection.

    If a person gets sick from COVID, depending on how old they are and if they have other health issues, they may or may not recover from a covid infection.

    Some States, or counties, are only giving the vaccine to people who are not sick. It is different in each State or county. Right now they are saying we may need to get the vaccine every year, just like we do for the flu virus.

    But this information may change, because as time goes by drug companies may develop a better vaccine. Some people who recover from the vaccine and develop antibodies,may not need the vaccine.

    All of this information may change because this is a new virus that keeps changing, mutating into different stains. Scientists are learning about this right now as they go along, so what they think today may be different then how they think about this virus and the vaccine next month. You just have to keep up to date on the information.

    You don't catch the same virus twice. 

    If the scaremongers are right and we can catch it over and over we might as well just have a huge kegger because it's all over for us.

    Right now there isn't a definitive answer on whether one should get the vaccine if they have already been confirmed to have been COVID positive. There's a consensus opinion that they probably should get the vaccine especially if it was a long time ago. 

    The vaccine at the very least would create a booster to create more memory cells in the future. 

    No one knows how long immunity lasts with native infections or with vaccines which is why the answer to first question is when in doubt vaccinate again. 

    It obviously takes time to follow along to see how long immunity lasts in real time in people by testing regularly in the future.

    Give us 5-10 years to answer the questions when we can give more definitive answers.

    Still need the vaccine. Virologist statements say that  the other 2 issues are unknown at this time.

    Contracting COVID doesn't reliably convey protection. There have been cases of people who have suffered mild COVID that didn't create enough antibodies later contracting more serious COVID.

    Current estimates of how long immunity from contracting COVID lasts range from three months to eight months. It is too early to say how long immunity conveyed by the vaccine lasts but there must be optimism it will last at least a year and annual jabs will be enough.

    Yes, because the vaccine will protect him from the next variant to come along.
