Covid infection induces high levels of immunity but patients still
able to carry virus, study shows

Natural immunity lasts at least five months, according to research
from Public Health England

Infection with Covid-19 provides up to 83 per cent protection against
the virus for at least five months, a new government study has shown -
though experts have warned that those with natural immunity may still
be able to carry and transmit the pathogen to others.

Research conducted by Public Health England (PHE) has found that prior infection offers levels of protection similar to those induced by the
Covid-19 vaccine, with only a small proportion of people retesting
positive after primary exposure to the virus.

In those rare instances of reinfection, most did not display any
symptoms, according to the first report from PHE's Siren study - which
has been regularly testing tens of thousands of healthcare workers
across the UK since June.

However, this means that many people who contracted the disease in the
first wave may now be vulnerable to catching it again, PHE said, as it
urged people who have been infected not to let their guard down.

PHE said although those with antibodies are unlikely to become ill
again with Covid-19, early evidence from the next stage of the study
suggests that some of these individuals can still carry high levels of
virus and continue to pass it on to others.
