Do you need to strengthen the injection after 6 months of vaccination with COVID-19 vaccine?
Relevant data analysis is in progress, and it is preliminarily judged that about half of the people still have certain defense ability against the virus; According to the follow-up experiments, it will be determined when the vaccinated population will be vaccinated. At present, the most important thing is to complete the first vaccination as soon as possible and establish an immune barrier. If you want to stop the virus from mutating, you must stop its spread and give it no chance to mutate.
Six months later, the monitoring data of large groups are being analyzed. According to the preliminary understanding, about half of people's antibodies are still ok. With the support of scientific data, we will determine when people who have been vaccinated for a long time in China should get booster shots.
The so-called booster needle is to decide whether to supplement the injection according to the immune regression in the follow-up experiment after the first complete vaccination of the vaccine, so as to maintain the human immunity to the virus. According to the expert's explanation, according to the current research, some people still have certain defense ability against the virus after six months of vaccination. Therefore, the most important thing at present is to complete the first vaccination as soon as possible and establish an immune barrier. At present, China's vaccination capacity and people's wishes have also been greatly improved. With the acceleration of vaccination process in various places, the demand for vaccines in COVID-19 has become more urgent, which poses a great challenge to the vaccine supply in China.
How to choose three COVID-19 vaccines?
Recently, all localities have adopted various flexible ways to let people who need vaccination get vaccinated as soon as possible. At the same time, there are more and more kinds of vaccines for everyone to choose from. COVID-19 vaccine used in China includes three different types: one-shot adenovirus vector vaccine, two-shot inactivated vaccine and three-shot recombinant protein vaccine, so the choice of vaccination is more flexible.
So, what are the characteristics of these three vaccines? It is understood that only one injection is an adenovirus vector vaccine. Generally speaking, adenovirus, like a truck, can carry COVID-19 nucleic acid fragments, which can be efficiently transported to cells to express antigens, and one injection can induce immune protection response. What needs two shots is inactivated vaccine, which is the traditional vaccine that everyone is familiar with. It inactivates the live virus and inoculates it into the human body as an antigen. The composition of the vaccine is closest to the natural virus structure. What needs three shots is recombinant protein vaccine, which is to make the most effective antigen component into vaccine through genetic engineering. Although these three vaccines are of different types, they are all safe and effective.
