On June 15, Zhang Zhoubin, deputy director of the Guangzhou Center for Disease Control and Prevention, stated at the local epidemic prevention and control press conference that in accordance with the unified deployment of Guangdong Province, during the period from June 13th to 30th, Guangzhou City will mainly target those who have already been vaccinated. People who have received the new crown vaccine will carry out the second dose of vaccination, and the first dose of vaccination will not be carried out temporarily.
To put it simply, in Guangzhou, people who have not been vaccinated will not have the first shot this month.
China News Weekly noted that Guangzhou is not the "first mover" in the suspension of the first dose of vaccine. At present, the first dose of new crown vaccine has been suspended in many places across the country, including Henan, Liaoning, Jiangsu, Hubei, Shaanxi, Anhui and other places.
According to Cui Gang, the second-level inspector of the CDC of the National Health Commission, the second dose of vaccination will be carried out from June 10th to 30th, mainly for target populations who have already received the first dose. However, for those with special needs, such as going abroad, immunization services are still required in various places. After July, the first and second doses of vaccination will continue to be fully promoted.
The first dose of vaccination has been suspended this month
In fact, as early as Guangdong Province, there have been reports of suspension of the first dose of new crown vaccination in many places. A Shanghai citizen received a text message at the end of May, in particular, saying that “there is no first injection after June 8th.” The community notice received by residents of Hefei, Anhui also stated that “the first injection of the new crown vaccine will be stopped from June 10th. , Fully transferred to the second needle stage".
for example
A staff member of a public institution in Tongling City, Anhui Province told China News Weekly that two days ago, his unit organized the second shot and a colleague also wanted to go to get the first shot together, but the organizer found that the first shot was reserved. The system has been temporarily shut down.
After making calls to more than 20 vaccination sites in Shanghai, Hebei, Henan, Shandong, Heilongjiang, Fujian, Jiangxi, Jilin and other provinces and cities, China News Weekly received a response to the suspension of appointments for the first injection, which will not be available until July. .
However, there are exceptions to provinces and cities. One is in Beijing. When a reporter called a community to ask when the first vaccination could be scheduled, the staff urged, “Bring your ID card, and hurry up while there are not many people.” The second is Tianjin, where the staff said they can now get the vaccination. Cansino vaccine (only one dose is required); the third is Haikou, Hainan. The staff said that Hainan household registration can make an appointment for the first injection, and it is necessary to call for specific vaccination time for foreign household registration in a few days.
According to incomplete statistics from China News Weekly, in addition to the above three mainland provinces and cities, Hong Kong, Macau, and Taiwan, other provinces and cities in China have successively issued official notices. Although the wording is different, several common points are: 1 .According to the work arrangements of superiors; 2. Call on the public to try their best to get the first dose of vaccine before June 9; From March 10th to June 30th, except for special reasons, the first dose of vaccination service will be suspended, and the follow-up dose will be fully prepared Sub-population services to ensure the effectiveness of vaccination.
Among them, special reasons include employees in key industries (such as cold chain transportation, etc.) and the need for entry and exit.
The work arrangements mentioned in the above notice are consistent with the work arrangements of the State Council’s Joint Prevention and Control Mechanism. At the State Council’s Joint Prevention and Control Mechanism press conference held as early as the end of May, Cui Gang, the second-level inspector of the CDC of the National Health and Medical Commission, pointed out that inactivated vaccines are widely used in China and two injections are required to complete the immunization program. Taking into account the turnover cycle required for the operation of the vaccine cold chain, in order to ensure the second dose of vaccination, all localities should further refine the vaccination plan.
But a question that the public is generally curious about is whether to ensure the supply of the second dose contradicts the first dose of the new vaccination? What impact will the 21-day window period of full vaccination with the second injection have on the epidemic prevention work?
Why give priority to the second needle?
Since the first local case of this round of epidemic appeared on May 21, as of June 17, the cumulative number of new local confirmed cases in Guangdong Province has exceeded one hundred. It is worth noting that in the above confirmed cases, there are cases where the first shot of the new crown vaccine is infected.
According to Lei Chunliang, director of the Eighth Hospital Affiliated to Guangzhou Medical University, among the local infection cases in Guangzhou, 4 patients were found to have received the first shot of the new crown vaccine, and they were infected before the second shot.
Lei Chunliang believes that it has been discovered that as long as the vaccine is vaccinated, even if the two doses of vaccination are not completed, the basic condition is not serious. The results of clinical feedback show that the vaccine is very effective in preventing severe illness.
In other words, vaccination is still essential to prevent severe illness and avoid serious sequelae. At the same time, for vaccines to have a high effect, full immunization is also very important.
There are now three types of new coronavirus vaccines on the market and in use in China, namely, inactivated vaccines, adenovirus vector vaccines and recombinant protein vaccines. The doses of the three vaccines are not the same. A large number of people in the country are vaccinated with inactivated vaccines, and the number of doses that need to be vaccinated is two.
To put it simply, in a two-needle vaccine, the first needle is the initial needle, which stimulates the immune system, and the second needle is a booster needle, which induces stronger antibody formation, thereby promoting the complete formation of the vaccine's immune response.
In an interview with China News Weekly, Academician Zhong Nanshan said, "In order to produce enough antibodies in the body, it is better to have a second injection 4-6 weeks after the first injection."
Chen Aqun, deputy director of the Institute of Immunization, Jiangmen City Center for Disease Control and Prevention, Guangdong Province, said in an interview with the media that from the perspective of individual protection effects, two doses of inactivated vaccines are more effective than one dose. Only after completing the entire vaccination, the human body can produce a better immune effect. The vaccination interval between the two injections is recommended to be ≥3 weeks (21 days), and the second injection should be completed as soon as possible within 8 weeks (56 days). So after 21 days after the first shot, please go for the second shot as soon as possible to get a better protection effect as soon as possible.
Regarding why the first dose is suspended and the second dose is given priority, the Jiangxi Provincial Health Commission has previously clearly replied that according to the requirements for the interval between two doses in the vaccination technical plan, in order to ensure that the first dose of new coronavirus vaccine has been vaccinated in the early stage The population can complete the second dose of vaccination in time within the time specified in the vaccination procedure.
The dean of a community hospital in Henan Province told China News Weekly, “At present, the first vaccination on our side has been completely stopped, and the first vaccination will be restarted on June 30. Generally speaking, two doses of complete vaccination are considered to be sufficient. To build an immune barrier, now it is mainly to ensure that people who have received the first shot before can get the second shot as soon as possible. If it is just the first shot of a large-scale vaccination, many people may not be able to get the second shot. In addition, this is also related to many people. People’s low awareness of vaccination is related to the long time interval between the two injections. Some people forget to get the second injection after the first injection."
Some analysts also believe that the supply of the new crown vaccine library is tight. Because the current number of people for the first shot is significantly higher than the second shot, if you queue up for the vaccine, the second shot will spend a lot of time and energy waiting, which is not conducive to complying with the requirements and time. Complete the standardized vaccination of the new crown vaccine.
However, judging from the current situation in various places, a new round of first vaccination will start in July.
