Previous coronavirus infection does not prevent young people from

A PAST coronavirus infection does not secure youths versus reinfection, a brand-new research study has discovered.

Boffins have actually discovered that even with antibodies from a previous Covid-19 infection, getting a vaccine is still the top method to avoid getting coronavirus again and cut rates of transmission.

Researchers studying more than 3,000 healthy members of the ultra-fit United States Marine Corps, many aged 18-20, found around 10 per cent who had previously had Covid got it again.

That compared to around half of those picking up the infection for the first time in between Might and December last year.

Although the study was in young, fit, mainly male recruits, the researchers think the danger of reinfection uses equally to many young people.

Teacher Stuart Sealfon, of Icahn School of Medication at Mount Sinai, New York, and senior author of the study, said: “As vaccine rollouts continue to get momentum it is very important to bear in mind that, in spite of a prior Covid-19 infection, young people can catch the infection once again and might still transfer it to others.

” Immunity is not guaranteed by previous infection, and vaccinations that provide extra protection are still needed for those who have actually had Covid-19.”

The researchers explained the precise rates of reinfection would vary from the study, due to the fact that crowded living conditions on a military base and close contact required for standard training likely add to a higher overall infection rate.

Comparing the brand-new infections between patients who had Covid for the first time and those who were reinfected, the professors discovered the amount of quantifiable infection– or viral load– differed.

In reinfected marines, the viral load was on average only 10 times lower than in those infected for the first time.

The authors believe this suggests some reinfected people might still be able to transmit the infection.

The research study published in The Lancet Respiratory Medicine journal also revealed most brand-new cases– 84 percent of those infected with Covid in the past – were asymptomatic while 68 per cent of those having coronavirus for the first time had no symptoms.
