For global crown disease strains xbb.1.5, Hong Kong epidemic prevention experts said that primitive vaccines are almost invalid for it, but binary vaccines still have a certain effect.
According to the report on January 10th, Xu Shichang, an expert consultant of the Hong Kong government and a lecturer professor at the Central Respiratory System Science Science Section, said that the mutation of XBB.1.5 spiny protein made the virus more likely to stick to the human respiratory tract.As a result, it has a stronger communication. It is one of the strongest propagation among the existing Omikon strains.
Xu Shichang quoted the test results of the Fu Bitai Pharmaceutical Factory that the binary vaccine of the crown disease still has a certain effect on XBB.1.5, but the effectiveness of the original vaccine is almost none.
However, Xu Shichang said that although XBB.1.5 has strong propagation, it will not increase the severity of the condition.He also said that the oral medication of the crown disease is still effective for XBB.1.5, because oral drugs are for enzymes that make the virus breeding, so even if the virus varieties do not affect the effect.
Comprehensive Hong Kong vaccination and the characteristics of the strain, Xu Shichang judged that XBB.1.5 will not pose a great threat to Hong Kong.
XBB is derived from Omikon BA.2 virus branch, and then genetically mutations and become XBB.1.5.The earliest case was discovered in the United States at the end of September last year and early October.
