now, the vaccine problem has aroused people's resentment. Recently, there was a news that many children in Shangluo, Shaanxi Province were vaccinated with expired vaccines, which is shocking. Is overdue vaccination harmful to children? Last week, the food and Drug Administration named a batch of rabies vaccine of Changchun Changsheng enterprise as faulty, followed by two batches of DPT vaccine of Changchun Changsheng and Wuhan biology. That batch of rabies vaccine is said to be out of circulation. As many as 650000 batches were found to have problems.
Diphtheria is a kind of vaccine, which is used to prevent pertussis, diphtheria and tetanus. One dose of DPT vaccine should be given at 3, 4, 5 and 18 months respectively, four times in total.
The results showed that the children who had completed 4 times of vaccination had better protective effects: 85% for typical pertussis, 80-100% for tetanus and 95% for diphtheria.
Parents are concerned about these problems
Which vaccines have gone wrong?
Two production enterprises, Changchun Changsheng Biotechnology Co., Ltd. and Wuhan Biological Products Research Institute Co., Ltd. Changchun Changsheng biology company seems to have problems many times.
Official data show that the vaccines produced in Changchun are mainly distributed to Shandong Province, while those produced in Wuhan are mainly sold to Chongqing and Hebei Province.
What's wrong with the pertussis vaccine? Does it affect your health?
According to the announcement of the State Food and drug administration, the main problems of DPT vaccine were found that the item of "titer determination" did not meet the requirements during the inspection. That is to say, the immune effect can't reach the target, but it doesn't do much harm to human body. Parents can check the vaccination record of DPT on the children's vaccination certificate, compare the vaccine manufacturer and batch number, or consult the vaccination unit at that time. Parents whose children have been vaccinated should not worry too much. They should consult the epidemic prevention department or vaccination agency to see if they need to be vaccinated again.
In fact, it happened last year. The national health and Family Planning Commission and the health and family planning departments of Hebei, Shandong and Chongqing have organized experts to assess the situation in November last year and promised to take corresponding measures according to the assessment results. Specific treatment measures need to wait.
At present, there are only two batches of vaccines with problems, and no other vaccines have been reported with problems. Vaccination is a better way for children to prevent diseases. Don't avoid vaccinating children because of this vaccination incident.
