• CSB - I have been in an Imperial study and just got the latest results.
    Suspected I had covid 17th March last year.
    Had a (home administered) positive antibody test in October.
    Tested positive again (full lab dna test) end of Jan.

    So from my data, there are definitely pretty long antibody reactions.

  • New study out* suggests antibodies have a "half-life" of >200 days so you should be good for a while yet.

    *Hot off the press, not even been peer-reviewed yet
