Study Reveals Robust COVID Immunity Through Infection and Vaccination

A pioneering study headed by the University of Oxford has effectively examined human immunity against COVID-19 in individuals who possess antibodies against the virus.

The findings indicate that having had a prior infection combined with vaccination provides substantial protection against the initial COVID-19 variant.

Individuals without antibodies against a specific pathogen are termed 'seronegative,' whereas those with such antibodies are referred to as 'seropositive.' More than 99% of the UK populace and 59% of the global population fall into the seropositive category, indicating they possess antibodies against COVID-19. Consequently, locating seronegative participants for infection studies has become exceedingly challenging due to widespread prior exposure through infections or vaccinations.
