When a new virus like the new coronavirus appears and begins to infect humans, an important asset to fight ingenuity is the blood of those who recover from illness,media reported. These blood samples can help scientists understand how the immune system responds to it, and quietly help them find a cure for the disease.
That’s why the National Institutes of Health’s (NIH) Vaccine Research Center is calling on those who have been infected with the new coronary virus and are now recovering from it to donate blood.
“The first step was to track individuals who had recovered and find a way to measure their antibody response,” said Darrell Triulzi, director of the Department of Blood Transfusion Medicine at the University of Pittsburgh Medical Center. “
Scientists want to understand the intensity of the immune response to a coronavirus infection and how it can protect people from virus infection in the future. They also need to know how long this protective effect lasts, such as SARS, where long-term studies have shown that the virus’s protective immune cells disappear six years after the disease.
Preliminary studies of patients with new coronary pneumonia,which has not yet been published, suggest that they do produce high levels of antibodies, which virologists say is a sign that they will no longer get sick from the virus. Another unpublished study of monkeys found that they produced antibodies after contracting the new coronavirus, and that they would not get sick again if they were exposed to the virus again.
But Triulzi says more research is needed to see if these antibodies are really helpful for treatment.
In addition, scientists have used blood from patients with recovered new coronary pneumonia as a possible stopgap measure for treating the most at-risk patients, as the blood plasma of the recovering person may be filled with protective substances such as antibodies that, if injected into the patient, may help seriously ill patients fight the disease. It’s an ancient strategy that dates back to the 1918 outbreak of the Spanish flu in the United States, when doctors reported that it could help reduce the number of seriously ill patients. More recently, it has also been used in trials of MERS, H1N1 and Ebola treatment.
However, there are risks to the treatment, and researchers worry that the use of plasma could worsen the virus that subsequently infects it. This may be a temporary measure before more sophisticated treatments emerge, but for health care providers or the elderly, the benefits may outweigh the risks.
In addition, Triulzi points out, blood can help researchers study the new coronavirus, but that doesn’t mean the blood of people who have been infected with or have been infected with the new coronavirus is dangerous. Infectious viruses don’t stay in the blood for long after they get sick, so people with blood banks and blood transfusions don’t have to worry. “There are no reports of blood transmission and this is unlikely. “
During such a pandemic, it is more important than ever to rehabilitate patients to donate blood, if possible. “The demand for blood continues,” Triulzi said. There is no risk of contracting the new coronavirus during the donation process. “
