Catching Omicron variant 'does NOT provide immunity from reinfection'

Catching Omicron variant ‘does NOT provide immunity from reinfection’, scientists reveal – saying it helps explain the continued rise in cases

  • Latest study finds Omicron variant of Covid gives no immunity from reinfection
  • Imperial College researchers described it as ‘more stealthythan past variants
  • Previous variants provided some immunity from reinfectionbut not Omicron
  • Covid sufferers who caught the 오미크론 variant will not be protected from catching it again, according to scientists at Imperial College 런던.

    The investigators say Omicron and its evolutions could explain why Covid cases remain higher than predicted in the UK.

    Earlier studies found that past illnesses with Covid provided some immunity against re-infectionbut the latest research indicates that is not the case with the Omicron variant, 텔레그래프 보고.

    Prof Danny Altmann from the Imperial College’s Department of Immunology and Inflammation, 말했다: ‘The message is a little bleak. Omicron and its variants are great at breakthroughs but bad at inducing immunity, thus we get reinfections ad nauseum and a badly depleted workforce.

    ‘Not only can it break through vaccine defences, it looks to leave very few of the hallmarks we’d expect on the immune system.

    ‘It’s more stealthy than previous variants and flies under the radar, so the immune system is unable to remember it.

    Researchers have been attempting to understand why people become reinfected with omicron, often soon after recovering from a previous spell of the disease.

    Blood samples were collected from UK healthcare workers who were triple-vaccinated and with different infection patterns with Covid in order to understand antibody, T and B cell immunity.

    The research uncovered that among those who were triple-vaccinated with no past infection, Omicron provided an immunity boost against earlier variants such as alpha, beta, gamma and the original ancestral strainbut practically none against Omicron itself.

    Covid sufferers first affected during the first wave of the virus and then again with Omicron were also found to lack any immunitya trend labelled ‘hybrid immune dampingby researchers.

    Covid-19 deaths registered in England and Wales have continued to fall, though the size of the drop has been affected by the Jubilee bank holidays.

    총 186 deaths registered in the seven days to June 3 mentioned coronavirus on the death certificate, 통계청에 따르면 (우리).

    This is down 55% week-on-week and is the lowest number since July 2021.

    The latest total covers a period that includes the bank holidays marking the Queen’s Platinum Jubilee on June 2 과 3, when most register offices were closed.

    This means fewer deaths were registered than would normally be the case.
