Chinese elderly vaccine additional in vaccination rate is relatively low.NotGoing out of the epidemic, the prerequisite for reopening.For China, which has just been tied to epidemic prevention, it is particularly important to increase vaccine vaccination rates, because when large -scale infections on outbreaks in various places, the protection provided by vaccines will reduce the risk of post -infection and death.NotThe current vaccination in China does not have expected ideals.NotData released by the government, although the coverage of Chinese vaccination exceeds 90%, the proportion of adults adds only 57.9%, and the additional vaccination rate of 80 years old and older people is only 42.3%.NotThe New York Times reported that the World Health Organization stated that additional additions are particularly important for Chinese vaccines because most Chinese vaccines use analog virus technology, and their effectiveness of coronary virus is not as effective as MRNA technology.

Reuters, a doctor in Shenzhen said that the Chinese medical community is generally not generally not generalSuspected of the safety of Chinese vaccines, but compared with foreign MRNA vaccines, it still has questioning it.The doctor said: "At least half of the medical and educators want to get the MRNA vaccine, and refuse to vaccinate the Chinese vaccine."
Experts are worried that the lack of effectiveness in domestic vaccines and the low vaccination rate of fragile population may leadAnd death.They suggested that the government should speed up the approval procedures for new vaccines to fight new coronary virus variants.NotThe Financial Times reported that Jin Dongyan, a professor at the School of Biomedicine of the University of Hong Kong, believes that in order to better cope with the "tsunami upstream" of the epidemic, China should have a acceleration mechanism when approving the vaccine to change the vaccine according to the epidemic strains.Clinical Trials".NotChinese vaccine manufacturers such as Kexing and Sinopharm Group are conducting clinical trials on their Omikon vaccine.However, these vaccines still cause immune reactions with analgiaous virus technology.Jin Dongyan warned that when these new vaccines were approved by the regulatory bureau, other new variants may have already become strains that dominate the epidemic.For example, Omikon BA5 strains, which were originally popular in many countries, have been replaced by new mutant strains in the United States; in Singapore, XBB strains have been replaced by XBB strains.NotA consultant of the Centers for Disease Prevention and Prevention in Beijing said that China's epidemic toolbox needs to add local MRNA vaccines.At least seven pharmaceutical companies in China are studying MRNA vaccines, some of which have entered the later stage of clinical trials.However, it is expected that "the fastest will not be launched until April next year."NotSaid that China's current most viable MRNA vaccine solution is to approve the MRNA vaccine made by foreign manufacturing.NotAny mRNA crown vaccine
Experts suggest that heterogeneous vaccine addition agent
In fact, the Chinese people turn their attention to other styles of vaccines.Recently, many medical experts have suggested that the public choose to choose a heterogeneous vaccine addition to improve the prevention effect.NotInfectious disease expert Professor Zhang Wenhong led the research team to point out in a research results of sequential vaccination to Omikon that strengthening vaccination of homologous vaccines or heterologous vaccines can improve the level of neutralized antibodies.However, the effects of heterrogenation will be better.
Zhong Nanshan, an academician of the Chinese Academy of EngineeringThe effect of MRNA vaccine, sub -unit protein vaccine, adenovirus vaccine and other technical route vaccines is better than completely vaccinated vaccine.NotIt is also pointed out that the results of real world clinical research show that the role of Chinese vaccine with restructuring protein vaccines in preventing infection is not inferior to foreign three -dose MRNA vaccines.It emphasized that "China's vaccine will not be worse than MRNA vaccine, we have confidence."NotSoutheast Asia and the Middle East countries, which are mainly used in Chinese vaccines, have successively changed their policies to apply other vaccines since last year, or add a MRNA vaccine.After the Indonesian front -line medical personnel were vaccinated with two doses of the Koxing vaccine, they added one dose of Modner vaccine at the end of last year; Barin urged the country to vaccinate the country after two doses of national medicine vaccine over 50 years old.It is also announced that the Getoko vaccine will be mixed with the Astraon vaccine.NotFor severe epidemics, whether it can increase the additional inoculation rate in mainland China in a short period of time, to a certain extent, it decides how heavy this epidemic will be.It turns out that whether it is an active vaccine or the MRNA vaccine, it can play a protective role, and the official approval of more styles of vaccine under the conditions of conditions will give people more choices.Life order.
