In recent days, the Changchun Changsheng vaccine incident has set off a hot topic. Countless parents turn over their children's vaccine books, denouncing the bad behavior of drug companies, and at the same time, they should know the seven answers to the most questions. Let's take a look
A: the outbreak of DPT vaccine is actually a problem at the end of last year, specifically including two manufacturers, Changchun Changsheng Biotechnology Co., Ltd. and Wuhan Institute of Biological Products Co., Ltd.
According to official data, the "problem vaccines" are mainly produced in Changchun and sold in Shandong, while those produced in Wuhan are mainly sold in Chongqing and Hebei.
2. Q: what's wrong with the event related DPT vaccine?
A: the main problem of DPT vaccine is that the titer index is unqualified.
The consequence is that it may affect the immune protection effect, but it is not harmful to human body.
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.
The national health and Family Planning Commission and the health and family planning departments of Hebei, Shandong and Chongqing provinces (cities) have organized experts to assess the situation in November last year, and promised to take corresponding measures according to the assessment results and properly handle it.
3. Q: what are the consequences of vaccination? Is there any possibility of sequelae?
A: this batch of vaccines has no impact on the safety of human body. The biggest risk is that they may fail to prevent corresponding diseases.
Many parents are worried about other sequelae when their children are vaccinated.
In fact, the common adverse reactions of vaccine include local redness, swelling, fever, allergy, etc., which are generally mild. The incidence of allergy is very low. For most people, the vaccine is safe.
The adverse reactions caused by the vaccine usually occur within 24-48 hours after vaccination, and the possibility of recurrence or sequelae is very small.
4. Q: how to make sure if you have been vaccinated with unqualified vaccine? What if you have been vaccinated with pertussis vaccine?
A: 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.
In the vaccination record, the vaccine batch and the enterprise DPT vaccine need to be inoculated 1 time in 3, 4, 5 month old and 18 month old respectively, a total of 4 times.
Normally, children who have completed 4 vaccinations can get better protection effect:
The effect of preventing typical pertussis is about 85%;
The protective effect of tetanus is 80 ~ 100%;
When inoculated more than three times, the protective effect of diphtheria was about 95%.
However, the two batches of DPT vaccine, which were not qualified in titer index, may affect the immune protection effect.
If parents decide that their children are vaccinated with pertussis vaccine, they can consult with the local disease control department or vaccination unit to see if they want to continue to vaccinate.

Marked the child's household registration unit's phone number 5, ask: the child has not been vaccinated against DPT, can you call?
A: Yes.
Pertussis vaccine can effectively prevent three kinds of critical diseases. At present, there are only two batches of pertussis vaccine, and other batches have no problems.
Moreover, the pertussis vaccine involved in the past has been stopped, so if you go to fight again, you won't encounter it. You don't have to worry too much.
Don't give your child an injection just because you're worried about the vaccine.
If parents really have doubts, they can give priority to the combination vaccine or choose the vaccine produced by other more reliable enterprises.
6. Q: other kinds of vaccines that my children have been vaccinated are also related to enterprises. Do they also need to be supplemented?
A: for the time being, there are no problems with other batches of vaccines. We suggest you calm down and keep your attention.
There are some risks in vaccine replanting. Do not replant blindly.
Dr. lilac will pay attention to the progress of the event as soon as possible and broadcast it to you.
7. Q: in order to prevent vaccination to the problem vaccine, can I not vaccinate the child?
A: you can't stop eating because of choking. You can't give up vaccination because of fear. The child is the most at risk.
At present, the reason why the country can control diphtheria, pertussis and neonatal tetanus at a lower level is the high vaccination rate.
If all vaccinations are refused because of the panic caused by these events, it is all people who will be injured.
According to the monitoring data of the State Food and drug administration, since 2008, 944 batches of vaccine products have been sampled in the national drug sampling plan, with a qualified rate of 99.6%. That is to say, most vaccines are very safe.
Hepatitis B, measles, pertussis and varicella, which are prevented by the first kind of vaccine, all of these diseases pose a great threat to children's health.
Therefore, vaccination is still the best way to protect health, we should still insist on vaccination.
Vaccine is the most favorable weapon for human beings to fight against infectious diseases. Only when enough people are vaccinated can a broad and powerful defense be formed.
The development of things up to now does not mean that the matter has come to an end. Everyone should be vigilant.
