In the fight against the new crown epidemic, China's vaccine arsenal may be "on the new" -
On April 26, Sinopharm's China Biological Aomi Kerong variant inactivated vaccine for the new coronavirus was approved by the State Food and Drug Administration. It is reported that China Biologics will use randomized, double-blind, cohort studies to conduct sequential immunological clinical studies in people aged 18 years and older who have completed 2 or 3 doses of COVID-19 vaccination to evaluate the safety and immunogenicity of the inactivated vaccine of the New Coronavirus of the Semikron variant.
The COVID-19 pandemic has been raging around the world for more than two years, and there is no sign of stopping, because the new crown virus has always mutated. Recently, WHO added two new auto-variants of Omi kerong, BA.4 and BA.5, to the test list, and the recombinant XE virus has accelerated its spread around the world, and XD, XL and other strains have also appeared. If you go on like this, the letters will run out of words, borrowing a line from the movie "Crazy Alien": "This is not the end of you." ”

The magic is one foot high, and the relevant research is also following up at the same time. Vaccines with different technical routes and different variants have been successfully developed and widely vaccinated on a large scale, and the protection of the population against the new crown virus has been improved. Vaccines have proven to play a huge role in preventing infections and preventing severe diseases and reducing deaths.
However, it should be noted that there are currently 267 million people aged 60 and above in China, and more than 50 million elderly people have not completed the full vaccination of the new crown vaccine. There are only a few reasons: some think that they are reclusive, have no social activities, the risk of infection is not high, and do not need to be vaccinated; some feel that the vaccine protection effect is not large, and whether they fight or not is the same; some are worried about the adverse reactions after vaccination affect their health; and some want to "hitchhike" and hope to rely on others to build an immune barrier. At the same time, the new crown vaccine is still a second-class vaccine in China, not a "compulsory vaccination" of the first-class vaccine, and must follow the principle of "informed, consent and voluntary" vaccination.
Increasing vaccination rates remains a top priority. To do this, ideological work and science popularization work are very important.
First, it turns out that speeding up COVID-19 vaccination is an important way to protect lives. According to data from the Shanghai Municipal Health Commission, as of April 25, there were 190 deaths in Shanghai, with an average age of 82.52 years old, and 86.32% of the total number of deaths over the age of 70; and among the deaths, only 12 cases had been vaccinated against the new crown, and the rest had not been vaccinated against the new crown vaccine – this is the role of vaccines in preventing severe diseases.

Similarly, according to information provided by the Hong Kong Department of Health, when the Hong Kong Omilon variant was endemic, the case fatality rate of the unvaccinated whole population reached 2.87%, of which the unvaccinated elderly over 80 years old had a case fatality rate of 15.68%. People over the age of 60 have a 252-fold risk of death than people under the age of 30.
It can be seen that the harm of the Omiljung variant is still considerable for the elderly, especially the elderly who are not vaccinated and have chronic underlying diseases.
Second, speak with science. The new crown virus not only mutates quickly, but also the direction of mutation is difficult to say. Wu Zunyou, chief expert of epidemiology at the Chinese Center for Disease Control and Prevention, said that our understanding of the new crown virus is still very limited, and the future development direction of virus mutation and epidemic situation is very complicated, which may develop in the direction of increasing infectivity and weakening pathogenicity, and may also develop in the direction of increasing infectivity and pathogenicity.
Since we cannot wait for the virus to recede on its own, we must actively take action. For individuals, vaccination protects both their own health and the health of their families and those around them; for countries, vaccination can reduce infection, severe illness and mortality rates, and can effectively interrupt the spread of the epidemic and ensure the health of most people. Vaccinations are also a social responsibility if physical conditions permit.
You have to speak with service. For special people who are seriously ill and bedridden, have limited mobility or are too old, they can send vaccines to their homes and send services to their homes, so that vaccines can "run more" and the masses can run less errands. This is effective in increasing the vaccination rate of the elderly, and there are some practices in various places. Now some places with economic strength have launched various types of "prize vaccinations", whether it is rice flour oil or telephone cards, shopping cards, and lottery tickets, and do everything possible to attract the masses to increase the vaccination rate.
In short, we must find ways to increase the vaccination rate of new crown for key groups and the elderly. This is not only a vivid embodiment of the supremacy of the people and the supremacy of life, but also necessary for China to restore the normal rhythm of production and life in the future.
