According to a press conference held by the Joint Prevention and Control Mechanism of the State Council on December 19, key populations will be vaccinated nationwide. On the evening of December 20, Tao Lina, a former vaccine physician of the Shanghai Centers for Disease Control and Prevention, told the Health Times that according to industry news, my country’s first batch of new crown vaccines is expected to be vaccinated 50 million times, and the first dose will be completed on January 15. The second stitch was completed on February 15. The details are still subject to official notification.
"my country's new crown vaccine application is at the forefront of the world. my country signed the emergency use of the new crown vaccine in July. It is expected that the new crown vaccine will be listed at the end of this year or early 2021 and will be officially launched in early April next year," Taolina said "And foreign countries just approved the emergency use of the new crown vaccine in December."
How to treat vaccine side effects
The U.S. Centers for Disease Control and Prevention introduced in a new crown vaccination guidance on the 19th that after the first batch of new crown vaccines were sent to all states in the United States on the 13th, 272,000 people have been vaccinated across the United States, and 6 people have suffered serious illness during the observation period. The allergic reaction was promptly treated. The U.S. Centers for Disease Control reminds that people who have had a severe allergic reaction to the first shot of the new crown vaccine should not get the second shot. The so-called severe allergic reaction refers to people who need to receive adrenaline treatment or hospitalization to relieve their symptoms.
At present, the FDA has approved two mRNA COVID-19 vaccines, one is jointly developed by Pfizer Pharmaceuticals Co., Ltd. of the United States and the German Biotech Company, and the second COVID-19 vaccine is developed by the United States Modena Biotechnology Company and the United States National Allergy and Infectious Disease Research Developed jointly.
Vaccine side effects cause concern
"There are many people who have some doubts about the safety of the new crown vaccine. In fact, this worry is unnecessary. The vaccine is different from the usual chemical drugs. The dose of chemical drugs is larger, and the metabolic mechanism of entering the body is more complicated. , May cause liver and kidney damage or affect the fetus. The dose of the vaccine is very small and only stimulates the immune system. Vaccines that do not contain live microorganisms will at most have immune-related adverse reactions, such as facial paralysis and allergies. Wait, these are also expected."
my country's new coronavirus vaccine has five technical routes, including inactivated vaccines, adenovirus vector vaccines, influenza virus vector vaccines, recombinant protein vaccines, and nucleic acid vaccines (mRNA vaccines, DNA vaccines). "Inactivated vaccines can be said to be the most mature vaccine technology. For example, the inactivated polio vaccine for children, inactivated hepatitis A vaccine, hand-foot-mouth vaccine, rabies vaccine, etc. are all inactivated vaccines. Rabies vaccines can even be vaccinated by pregnant women." Tao Lina said, "Recombinant protein vaccines have been very mature, including hepatitis B vaccine (30 years of application history), hepatitis E vaccine, cervical cancer vaccine and herpes zoster vaccine. Adenovirus vector vaccine technology also has a history of several years of application."
"MRNA vaccine is a new technology. Before the emergency approval, the number of users in the world did not exceed 100,000. Compared with vaccines of other technologies, its safety risk is greater, but it will not have unexpected adverse reactions." Tao Lina said.
Pay attention to the vaccination news of nearby community health service centers in time
Our country’s current strategy for new crown vaccination is to implement vaccination nationwide in accordance with a two-step plan.
"At this stage, we mainly carry out vaccination for some key populations, including those who are engaged in import cold chain, port quarantine, ship piloting, aviation air service, fresh food market, public transportation, medical disease control and other staff with relatively high risk of infection, as well as those who go to medium and high risks. People who go to work or study in countries or regions," Tao Lina said, "The general population can pay attention to the health service centers, township health centers or general hospitals near their homes, and news should be announced as soon as possible."
A reporter from the Health Times called a community health service center in Beijing, and further notification arrangements are still pending.
Inspector Jiao Yahui of the Medical Administration and Hospital Administration of the National Health Commission reminded all vaccinators at a press conference on the 19th that during the vaccination process, they must truthfully report to the medical staff their health status and what kind of underlying diseases they have. Is it in the onset of the disease? Is there a history of allergies? Is it allergic?
In addition, according to past experience, these adverse reactions often appear within 30 minutes after vaccination, so vaccinators must stay at the vaccination site for 30 minutes after vaccination. During this process, if some problems arise, medical staff can deal with them in time. After 30 minutes, you can go home without any problems. After going home, even if you have the symptoms related to the adverse reactions just mentioned, you should seek medical treatment in time. At the same time, I also remind all vaccinators to pay attention to diet, rest, and keep the vaccinated area clean and dry, so that the body functions can return to normal as soon as possible.
