“In short immunity, it leads to repeated waves of infection reflecting the patterns observed with common cold coronaviruses and influenza,” said Hiam Hemitely, the first author of the study and associate professor of the Department of Population in Weill Cornell Medicine-Qatar, in his statement by the field “This virus Here, in order to stay, and will continue to reinfection of us, just like other cold coronaviruses. Regular vaccines updates are crucial for the resumption of immunity and protect vulnerable population groups, especially the elderly and those who have the main states of health. ”

Chemitelly and colleagues suggest that the shift in the pandemic came from the “shifts in the evolutionary pressure that the virus faces. In the early stages of the global crisis, the virus developed and spread due to an increase in its transmission. Then, when the virus pressed the world, and the populations began to create immunity, the virus came across pressure to evade this immunity.

Nevertheless, the fact that researchers did not find such a decrease in protection against severe, deadly Covid-19 suggests that evasion is probably aimed only at certain components of our immune system. As a rule, neutralizing antibodies that can block viral penetration into cells are primary protection against bride infection. On the other hand, immunity against severe diseases is cellular mechanisms, such as T -cells of memory that, by the visible, do not affect the pandemic shift, researchers write.

In general, the study “emphasizes the dynamic interaction between the evolution of the virus and the owner’s immunity, which requires further monitoring of the virus and its evolution, as well as periodic updates of the SARS-COV-2 vaccines to restore immunity and counteract continuous viral immunity”, Chemaitelly and colleagues are consisted .

However, in the USA the future of annual vaccines updates may be in question. An outstanding lawyer to combat the vaccine and the theorist of the conspiracy Robert F. Kennedy Jr. is ready to become the main official of the country’s health care, awaiting the Senate confirmation next week. In 2021, when Omicron first scattered around the country, Kennedy submitted a petition to the Products and Medication Management Management and Covid-19 access and approval cancellations and approval.
