According to the Voice of China News Horizon, last year, some media reported that nearly 400 children in Shenqiu, Zhoukou, Henan Province had received vaccines that were overdue for half a year, and some children had adverse reactions. The report also said that the vaccination work in Shenqiu, Zhoukou was chaotic, and some children nearly died because of improper vaccination. The reporter of CCTV verified that the report was not true.
The report lists the cases of adverse reactions caused by vaccination in Shenqiu, Zhoukou, Henan Province in 2014 and 2015. It is reported that in 2014, a three-month old baby experienced abnormal reactions such as high fever after receiving the acellular DPT vaccine. The child was vaccinated on June 6, 2014, but according to the query of the vaccine batch number shown on the vaccination certificate, the validity of the vaccine was in December 2013, so the vaccine has expired for half a year. In this regard, Yang Jun, head of the Family Planning and Immunization Department of the Shenqiu County CDC, said that the children's vaccines had not expired, and the parents' misunderstanding was due to the staff's failure to update the batch number of vaccines in the computer in time.
The report also pointed out that in 2015, doctors injected three kinds of vaccines to a one year old girl at the same time, which should not have been vaccinated at the same time. The girl almost died. Although the rescue saved her life, it left serious sequelae. Yang Jun, the head of the Family Planning and Immunization Department of Shenqiu County CDC, said to the "Yangguang Confirmation" that after the investigation of the Zhoukou City Expert Group on the Investigation and Diagnosis of Abnormal Vaccination Reaction, the illness of the child was not an abnormal reaction of vaccination, but a coincidence.
Yang Jun said, "She was vaccinated with three vaccines at the same time, one is leprosy vaccine, one is Japanese encephalitis attenuated vaccine, and the other is oral rotavirus vaccine to prevent autumn diarrhea In terms of the above, it is possible to vaccinate at the same time, including Zhoukou City has organized experts from relevant fields to carry out surveys in this regard, and there is no objection to the vaccination of the three vaccines ".
Although the media reports are different from the facts, it also reveals that there are still some irregularities in local vaccination management. The reason why this report was widely reproduced on the Internet is also related to people's concern about the safety of the vaccine. In recent years, the so-called vaccine safety incidents have been reported frequently, especially the hepatitis B safety crisis at the end of 2013, which caused a serious crisis of confidence in vaccine safety. Is our vaccine safe?
At the end of 2013, infant deaths caused by hepatitis B vaccination were exposed in many places. Although it was finally investigated that there was no safety problem with these vaccines, and the deaths were judged as "coincidence events", people still had a lot of concerns about the safety of vaccines. Wang Huaqing, deputy director of the Immunization Planning Center of China Center for Disease Control and Prevention, explained in an interview with Voice of China that "coincidence events" and what people usually call adverse reactions are two concepts. Coincidence is that people will suffer from this disease no matter whether they are vaccinated or not, but the symptoms of the disease happen after vaccination, so this is a temporal correlation rather than a causal necessity. Cui Chen, a pediatrician from the US China Yi and the Comprehensive Outpatient Center, said that temperature rise is a common adverse reaction after vaccination, and parents can pay attention to observation but do not have to worry too much.
Cui Chen explained that the vaccine itself has actually changed the child's immune system function, so it may be because the vaccine has changed the child's immune system function. At this time, some other bacteria or viruses have taken advantage of the weakness, but the vaccine itself is not the cause.
Now many parents think that the expensive imported vaccines are effective and safe without side effects. Cui Chen pointed out that this is a mistake. As long as the vaccine passes the national inspection, it is safe and effective whether it is domestic or imported.
Cui Chen said, "The so-called effect needs to have a specific measurement standard. For example, if we need to vaccinate some vaccines twice or three times, then if the same effect is not achieved, then some vaccines may be only once, which is a relatively reduced number of times, which is a part of measuring the effect. However, the specific effect, how many people they are and how long they can have a certain protection rate, is also one aspect of measuring the effect. The proportion of adverse reactions and adverse events after vaccination is also one aspect of the effect, so we focus on its effectiveness, safety, simplicity and Economics These aspects of sex are considered. Vaccine is a public health field, so it is not only about the impact on individual children, but also about the comprehensive consideration of regional economy and other factors. Therefore, parents should be truthfully informed of these and given such a choice ".
