Catching COVID provides eight months’ immunity against reinfection, government scientists say
Catching coronavirus provides at least eight months of immunity against reinfection, government scientists have said.
“Infection with SARS-CoV-2 leads to antibody, B cell and T cell responses in almost all individuals, which are sustained for over eight months after infection,” the government’s NERVTAG group said on Friday.
NERVTAG said that people who contract COVID-19 have an 81% chance of not being reinfected or developing symptoms from the virus again for at least seven months.
This is much less – only 47.1% protection – for those aged over 65 for the same time period.
People who are infected with coronavirus have 69% protection against getting the virus at all for at least six months, but only 40% protection against getting the virus and being asymptomatic during that time, the scientists said.
All data is based on people testing positive from a PCR test.

It comes after other data from the Office for National Statistics earlier this week suggested that eight in 10 adults now have coronavirus antibodies, meaning they’ve either been infected or vaccinated.
But the amount of antibodies people have will depend on factors such as how recently they were infected, how many vaccine doses they’ve had, and the time since their last jab.
