First of all, the vaccination amount in COVID-19 exceeds 654.38+0 billion doses.
According to the data of National Health Commission, as of March 27th, a total of 7000 doses of COVID-19 vaccine1024/kloc-0 were reported all over the country. In fact, in the past few days, the number of people vaccinated in China has increased by millions every day, which shows that after two or three months of full preparation, the vaccination of COVID-19 vaccine in China has been carried out on a large scale.
Second, how long does it take to establish an immune barrier?
1. How to understand the immune barrier?
To establish an immune barrier in COVID-19, it is necessary to complete the large-scale vaccination of COVID-19 vaccine. According to the current vaccination effect of vaccines in COVID-19, epidemic prevention experts suggest that the mass vaccination data is 80% of the whole population, in other words, at least 1 1 100 million people need to be vaccinated.
2. Vaccination coverage in COVID-19 is still expanding.
At present, the vaccination population in COVID-19 is mainly adults aged 18 ~ 59, and some provinces and cities such as Beijing, Han and He have begun to vaccinate people over 60. I believe that in the next step, not only more areas will release the vaccination of people over 60 years old, but also people under 18 years old will be released in due course according to the situation.
3. When can I establish immune protection?
The output of vaccines in COVID-19 determines the vaccination quantity in COVID-19. At present, the daily output of COVID-19 vaccine in China is about 5 million doses, and this figure will gradually increase with the progress of time. Based on an average of 7 million doses per day, the large-scale vaccination of COVID-19 vaccine in China can be basically completed in about 300 days, that is to say, by the beginning of next year, the domestic immunization guarantee can be established.
To sum up, at present, the vaccine supply in COVID-19 is getting more and more sufficient, and all localities have carried out vaccination work for the general population except the key population, especially in highly concentrated places such as colleges and universities, and efforts are being made to complete the vaccination work for all. Eat the rice bit by bit and walk step by step. The establishment of immune protection in China needs everyone's joint efforts.
