The study warns that the past infected coronavirus “is not completely protected against reinfection”

by

Young people who have previously been infected with coronavirus will not be fully protected against reinfection, according to a new study.

Researchers at Mount Iinahn School of Medicine in Sinai analyzed data on more than 3,000 healthy U.S. Marine Corps members between the ages of 18 and 20.

They found that approximately 10% of those involved in the study who had previously been infected with Covid-19 were re-infected.

The study’s authors warned that despite previous infection and the presence of antibodies, vaccination is still needed to stimulate immune responses, prevent reinfection and reduce transmission.

They added that young people should get the vaccine whenever possible.

People “could be re-infected with Covid every two to four years” as the virus moves into new variants

Mutant variants of coronavirus could reinfect people every two to four years, a top scientist warned.

Paul Hunter, a professor of medicine at the University of East Anglia, said it was normal for future strains to appear and that they would not necessarily cause serious illness.

But he warned that “it is very difficult to predict” because “you never really know what each new variant will do”.

Government advisers are already finding that vaccines are less effective for existing variants, including up to 30% less effective for South Africa.

The highly transmissible mutations first detected in Kent and Brazil are referred to as “worrying” and also lead to a third wave across Europe.

Professor Hunter pointed out that many new variants are not a cause for concern, but should be monitored to ensure that the roadmap for lifting the lock does not derail.

According to the observational study conducted between May and November 2020, 19 out of 189 Covid-infected Marines caught the virus again.

This was compared with new infections in 50% (1,079 of 2,247) of participants who had not been previously infected with the virus.

Although the study was suitable for young recruits, especially men, the researchers believe that the risk of reinfection will apply to many young people.

However, the exact reinfection rates will not apply in other conditions, due to the crowded living conditions on a military basis.

The team said the close personal contact needed for basic training is likely to contribute to a higher overall infection rate than elsewhere.

For example, a study of four million people in Denmark found that the risk of infection was five times higher in people who had not had the disease before.

But the researchers found that only 0.65% of those who had Covid-19 during Denmark’s first wave tested positive again during the second wave, compared with 3.3% of people who were positive. after they were initially negative.

In addition, a prepress study involving British healthcare workers found that those who had not been previously infected were five times more likely to be infected than people who had a previous infection.

Professor Stuart Sealfon, lead author of the study, said it was important to remember that despite a previous infection, young people could catch the virus again.

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

Recruits who tested positive for the second infection during the study were isolated, and the researchers underwent additional tests.

Neutralizing antibody levels were also taken from subsequently infected participants who were not reinfected during the study period.

Of the 2,346 participants who followed sufficient time for this analysis, 189 were seropositive and 2,247 were seronegative at the start of the study.

In both groups, there were 1,098 (45%) new infections during the study, and of the recruits who were seronegative, 1,079 (48%) were infected.

The authors studied the responses of participants’ reinfected and uninfected antibodies to understand why these reinfections occurred.

They found that, among the HIV-positive group, participants who were reinfected had lower levels of antibodies against the virus than those who did not.

When they compared new infections, they found that patients who had the previous virus and became infected again had about 10 times less of the virus in their system than someone who had been infected for the first time.

This suggests that some re-infected individuals may still be able to transmit the virus, but the authors noted that further investigations will be needed.

In the study, most new cases were asymptomatic – 84% (16 of 19 participants) in the HIV-positive group and 68% (732 of 1,079) in the seronegative group – or had mild symptoms and none were hospitalized.

The authors noted some limitations of the study, including the fact that they may have underestimated the risk of reinfection in previously infected individuals.

This is because it does not take into account people with very low levels of antibodies after their past infection.

They also could not determine how HIV-positive recruits contracted their previous infection and confirmed it by the PCR test or determined how severe it was and what symptoms they had.

The researchers said they could also have missed detectable infections that appeared between PCR tests every two weeks during the study, published in The Lancet Respiratory Medicine.

“Although the antibodies induced by the initial infection are largely protective, they do not guarantee the effective activity of neutralizing SARS-CoV-2 or immunity against subsequent infection,” the study said.

A separate study published in the Lancet in March found that most people who had COVID-19 are protected from taking it again for at least six months, but older people are more prone to reinfection than younger people.

Only 2% of the positive results from the side flow are correct, says councilor Matt Hancock in the leaked emails after Boris Johnson asked the nation to take them twice a week

Only two percent of the positive results of the Covid lateral flow test performed in areas with low prevalence are accurate, warned a counselor of Matt Hancock.

In emails sent to the Guardian, senior strategist Ben Dyson is said to have warned colleagues in the health department about the reliability of the results of the side flow tests.

Dyson, who is executive director of strategy at the health department and one of Health Secretary Matt Hancock’s advisers, said he feared the reliability of positive results could be as high as two percent in some areas.

The email was reportedly sent on April 9, four days after Boris Johnson announced a multi-billion pound plan for a mass test in the UK – which would see the British tested twice a week with side flow tests.

According to The Guardian, Dyson said in his e-mail: “As of today, someone who gets a positive LFD result in (say) London has at most a 25% chance of it being a true positive, but if it’s a self-test potentially reported up to 10% (on an optimistic assumption about specificity) or up to 2% (on a more pessimistic assumption).
