COVID-19: Young people who have already had coronavirus are not fully protected against reinfection – study | UK News

Young people who have already tested positive for the coronavirus are not fully protected against reinfection, new research suggests.

A study of 3,000 members of the US Marine Corps, mostly between the ages of 18 and 20, found that 10% of participants (19 of 189) who had contracted COVID-19[female[feminine before being tested positive again.

This is compared to 50% of people who had not had coronavirus previously (1,079 out of 2,247).

The researchers behind the study, which was conducted between May and November 2020 and published in the journal The Lancet Respiratory Medicine, say it highlights the risk of COVID reinfection in young people.

They added that only vaccination will help reduce serious illness or death from the virus – and possibly transmission.

But they stressed that there were limitations to the study, including the overcrowded living conditions at the military base where it was conducted and the close contacts needed to provide training for participants.

This could have contributed to a higher rate of reinfection than in the rest of the population, they said.

Researchers say vaccination is the best way to prevent reinfection

Professor Stuart Sealfon, Icahn School of Medicine at Mount Sinai, new York, and lead author of the study, said: “As vaccine deployments continue to gain momentum, it’s important to remember that despite a previous infection with COVID-19, young people can once again catch the virus and can still pass it on to others.

“Immunity is not guaranteed by a past infection, and vaccines that provide additional protection are still needed for those who have had COVID-19.”

Similar studies in other countries have shown high levels of protection against re-infection from past infections.

In Denmark, for example, a study of four million people showed that only 0.65% of those who tested positive in the country’s first wave contracted the virus again in the …
