    Protective immune responses that build up during a SARS-CoV-2 infection may weaken just two to three months later—particularly if the infection didn’t come with any symptoms, a new study suggests.

    Could mean that a vaccine will also not be very effective.

    I 100% believe somebody posting on Instagram that she has caught it twice.... 100%
    Instagram types are not known for seeking attention at all

    Jaysus

    It's the New York Post, I'm sure they did a little bit of fact checking

    She's also far from the first to get it twice

    They literally quote her Instagram post as the source...

    Because many vaccines are designed to stimulate the immune system in a way similar to catching the virus. Some produce a mild form of the disease for example. But if "So much for antibodies!" as you say then this may not bode well for the development of a vaccine with lasting effect.

    Not an expert so I stand to be corrected.

    Why would someone working on TV for a publicly traded company lie about something so serious when said company recently tested loads of their staff?

    This company had several staffers test positive

    This company is based in Florida, a place riddled with it

    And - her and this company aside - what about the others who got it twice?

    I don't think the New York Post is seen particularly highly - I get the impression it's more of a tabloid, as opposed to the New York Times. That often leaders to weaker investigative journalism.

    The New York Post is a Murdoch owned celebrity rag. I doubt they are too worried about facts.

    I believe Oxford University said their vaccine should last about a year. So booster shots would be required after that.

    Well I would hope they are correct, but if we don't know in advance how long natural Covid-19 immunity might last, how would the team at Oxford know in advance how long their vaccine will work? What assumptions are they making in their estimate?

    If it turned out that natural immunity from the virus only lasts a couple of months which is not yet fully fact, then this may have an impact on the Oxford team's estimate.

    They are the experts. I would imagine they know what they are doing.

    I believe the amount of antibodies their vaccine is meant to produce is significant compared to someone who might be asymptotic or only has a mild illness due to Covid. But those antibodies will still fade over time.

    So much clickbait with every single website these days. I can barely find exceptions to it online anymore

    It's a clown show

    I hope you are correct and that whatever vaccine is produced confers a lasting immunity.

    But even when experts of world renown make estimates, they are based on what is known at the time and the rest is (hopefully stated) assumptions. So the estimate might be based on the assumption that a fairly long lasting immunity is gained through catching the virus. As new information comes in the estimates are adjusted.

    I would still maintain that long lasting immunity from the virus itself bodes well for the development of a vaccine with long lasting immunity.

    I would also suggest that multiple strains of the virus - which could be the cause of repeat infections - will also make development of a vaccine harder.

    Again, not an expert and open to correction.

    You know that's New York's version of The Sun so fact checking wouldn't be a thing!

    If people could get it twice I'm fairly sure there'd be a more credible source for this than a wrestling announcer.

    If you can get this twice, would that mean it wouldn't lie dormant to reactivate in the future?

    You can get chickenpox more than once,but most people dont


    Could be something similar?

    Good point. And you can get a chicken pox vaccine, which you get once (well 2 doses) and it's a once off vaccine, about 90% effective I believe.

    This type of claim goes way back to China in February or March where they found something similar. They blamed the tests.

    Its more likely to be a testing issue, but even if a tiny amount of people dont get anti-bodies it doesnt mean we all don't.

    This has been discussed numerous times over the past 5 months or so. No-one knows enough about this virus to understand how it evolves, or what immunity, if any, infection offers
