The Victory Over the New Coronavirus Pneumonia is Expected! New Research : Humans have Strong Immunity

The latest research has found that the human body produces a 'strong immune response' when it encounters the new coronavirus, which can protect the human body from further infection even when suffering from a mild disease. Although the exact duration of the protective power of this immune response is still unknown, current research results show that the staying power can last for more than several months. Experts say that the results of the study give people hope for defeating the virus and prove that vaccines may be able to successfully protect humans from infection.

At the beginning of the new coronavirus pneumonia pandemic, some scientists questioned whether the human body can produce antibodies against infection and the durability of antibodies. Some early reports showed that after a mild patient recovers, antibodies will decrease in a short period of time and immunity will quickly decline.

It is understood that U.S. researchers conducted blood tests on 15 patients with mild new coronavirus pneumonia and found that there were three signs of sustained immune response in the patients' blood: antibodies, memory B cells and memory T cells. Lauren Rodda of the research report said in an interview that patients still have 'the three layers of protection' after three months of recovery, which greatly reduces their risk of repeated infections. If these patients are infected again, the possibility of the illness becoming severe or contagious will also be high.

The research results show that the immune response can last for three months or even longer. Therefore, Rhoda pointed out that their research results prove that the U.S. Centers for Disease Control and Prevention (CDC) recommendation is correct, that is, the first three patients after infection No need to be tested for the new coronavirus within a month.

A well-known immunologist said that these findings prove that the upcoming vaccine is possible to protect people from COVID-19 in a short period of time. It is understood that a study shows that the new coronavirus will activate the important immune cells 'T cells' in human body. Such cells can stimulate various branches of the immune system, and can also attack and kill cells that have been infected by the virus.

Another study observed blood samples from blood donors and found that even if they have never contracted new coronavirus pneumonia, a high proportion of people in some parts of the United States have T cells that can recognize the new coronavirus. At present, the reason for this physiological reaction is unknown, but scientists believe that it may be due to the so-called 'cross protection' to prevent other coronaviruses from causing the common cold.

In an interview with CNN, Ian Lipkin, director of the Center for Infection and Immunity at the Mailman School of Public Health at Columbia University, said that although these preliminary findings have not yet been determined whether they are completely correct, it makes us more interested in winning this battle and feel optimistic about the war.
