  • Antibody titres refer to the presence, and amount, of antibodies within a person's blood.
    The research calls into question how much protection individuals who have had the coronavirus have from subsequent reinfection, and the durability of any potential vaccine.
    World Health Organization officials said Monday that patients who recover from Covid-19 may be able to get the coronavirus again, citing similar studies that suggest immunity may wane after a few months.
    Dr. Maria Van Kerkhove, head of the WHO's emerging diseases unit, said patients "do mount some level of an immune response."
    Speaking at a news conference at the organization's Geneva headquarters, she added that, "what we don't know is how strong that protection is and for how long that protection will last."
    "So there are a number of studies under way that are trying to answer these questions," she said.
    A peer-reviewed study published in the Lancet medical journal last week claimed that Covid-19 antibodies in Spain's population were "insufficient to provide herd immunity," which refers to when a population is allowed some exposure to the virus in order to build immunity among the general population

      • Immunity to the coronavirus may last only a few months, UK study finds
        Antibody responses to the coronavirus can peak three weeks after onset of symptoms, but then begin to decline after as little as two months, researchers at Kings College London found.
        The study examined the antibody levels of patients and health-care workers who had tested positive for the virus.
        WHO officials warned that studies suggest Covid-19 immunity may wane after a few months.
        Immunity to Covid-19 may last only a few months, according to a U.K. study that casts doubts over the longevity of potential coronavirus vaccines.
        Antibody responses to the coronavirus can peak three weeks after onset of symptoms, but then begin to decline after as little as two months, researchers at Kings College London found.
        The study, published Saturday on preprint server MedRxiv and not yet peer-reviewed, examined the antibody levels of 64 patients and six health-care workers who had tested positive for the virus at Guy's and St Thomas'NHS foundation trust (which runs several London hospitals) between March and June
