The World Health Organization stated on December 7 that hundreds of serological studies have been carried out on the COVID-19 around the world. Although these studies still have certain limitations, their results consistently show that most people in the world are still susceptible to the COVID-19.
The Director-General of the WHO Tan Desai stated at the press conference that day that the importance of serological research lies in its assessment of the degree of infection in different populations by looking for antibodies to the new coronavirus in the blood of individuals. Hundreds of serological studies on the new coronavirus have been carried out all over the world, with different detection methods.
He emphasized that although these studies still have limitations, the results are quite consistent, that is, most people in the world are still susceptible to the new coronavirus. At present, the WHO is still studying how strong the immune response of different populations against the new coronavirus is and how long this immune response will last.
The WHO initiated a study in January to standardize serological research and testing for the new coronavirus. To date, more than 60 countries are using the WHO programme to conduct one or more such studies.
Tan Desai said that serological research can help understand how long the immunity gained after infection with the new coronavirus can last under natural conditions, and also help understand how long the immunity gained after vaccination can last.
As countries plan to launch the new crown vaccine in the next few weeks or months, he called on countries to give priority to vaccinating the new crown vaccine for the people who need it most, including the higher risk of infection, based on the framework and roadmap released by the WHO Immunization Strategy Advisory Group Health workers and people suffering from serious diseases.
He also emphasized that in the initial stage of promoting the new crown vaccine, since only a small number of people in each country can be vaccinated, it is important that governments, communities and individuals continue to use proven and effective new crown response tools.
