Is this article related to the Shandong vaccine case?

< < Vaccine Wounds > > is an old manuscript by Caixin reporter Guo Xianzhong in 2013 and has nothing to do with the controversial Shandong vaccine case.

(1) All the vaccines mentioned in this old draft are Class I vaccines, but according to the current reports, all the problems in Shandong vaccine cases are Class II vaccines;

(2) Improperly stored vaccines are not toxic vaccines. The biggest problem is that they may fail, but the probability of serious adverse reactions such as disability or death is extremely low.

Such a report, released at this time, can easily cause the two events to be related to each other, thus triggering public panic about vaccines, which is debatable.

Since the publication of this article, many parents have offered to refuse vaccination.

The risk of disease infection caused by children not being vaccinated is far greater than that caused by problem vaccines, because all medical workers do not want to see the refusal to be vaccinated out of fear of problem vaccines.

The problem with the vaccine is what?

The biggest problem with the vaccine is that it may [fail], that is to say, it has no immune effect, which may lead to people who should have been protected not being protected.

At present, there are no reports of serious adverse reactions in what after vaccination of this batch of vaccines. In addition, as mentioned earlier, if the vaccine produces adverse reactions, it usually occurs within 24-48 hours after vaccination, and the possibility of recurrence in the later period is very small.

Should I still be vaccinated?

If it is a type of vaccine that belongs to planned immunization, it must be vaccinated on time.

All the vaccines found to be problematic this time belong to Class II vaccines, that is, vaccines that are not subject to compulsory immunization.

For children, the requirements of the vaccine book must be vaccinated, is a kind of vaccine. This kind of vaccine is free of charge, by the provincial government budget, bidding, unified distribution.

At present, the state has very strict management of a class of vaccines, and all links are open and transparent, so the probability of problems is very small. Please parents according to the time stipulated in the vaccination book, to immunize their children.

Do you want to take the second type of vaccine?

This can be seen that the demand for vaccination is what:

(1) If it is a vaccine used to nip in the bud, such as mumps vaccine, influenza vaccine, etc., you can wait and see, and then vaccinate when the case is further clarified.

(2) If vaccination is urgently needed, for example, after being bitten by stray dogs, immunoglobulin and rabies vaccine need to be vaccinated. Do not delay and vaccinate in time.

What if you may have been vaccinated with the problem vaccine?

As mentioned earlier, the biggest risk of this batch of vaccines in Shandong is that they may fail, resulting in the failure to prevent corresponding diseases.

Parents can consult the disease control department or vaccination unit for replanting after determining the type of vaccine.

Vaccines such as influenza and oral rotavirus are vaccinated once a year, as long as they continue to be vaccinated on time this year.

There are also parents who worry that the failure of rabies vaccine will lead to direct illness. Because most people use freeze-drying technology for rabies vaccines, The tolerance to temperature is stronger than that of common vaccines. Some studies suggest that the immunity of freeze-dried vaccines is still in a relatively high range after being stored at 25 ℃ for one month. Moreover, the average incubation period of rabies is about 1-2 months. Up to now, there have been no reports of rabies cases caused by injection of vaccines involved in the case.

Will problematic vaccination lead to sequelae such as paralysis?

Vaccines act on human body in a very small dose, and their adverse reactions are mainly divided into three types:

(1) The first is local redness, swelling, heat, pain and fever caused by inoculation.

(2) The second is allergic reaction related to immune mechanism;

(3) The third is infection caused by live bacteria or viruses in attenuated live vaccines.

For most people, vaccines are safe. Just like driving can be killed, the incidence of vaccine disability is extremely small, only one in a million.

We should also tell you that if the vaccine produces adverse reactions, it usually occurs within 24-48 hours after vaccination, and the possibility of recurrence in the later period is very small.

If you don’t get vaccinated because you are worried about adverse reactions, you will stop eating because of choking. For most children with normal immune mechanism, it will definitely do more harm than good.

However, the painful children in the article “The Wounds of Vaccines” have nothing to do with the problem vaccine case in Shandong. The essential problem of this incident is the lack of supervision of vaccines during circulation.

What are the types of problematic vaccines exposed this time?

These vaccines investigated and dealt with are not [toxic vaccines], but also qualified products produced by regular manufacturers. However, there are problems in the transportation and storage links. The worst possibility is that the vaccines will fail and cannot play the role of immune prevention.

According to the initial report, there are 25 kinds of vaccines including meningitis, chickenpox, poliomyelitis and other vaccines for children and influenza, rabies, hepatitis a and other vaccines for adults.

At present, there are 12 kinds of vaccines verified by relevant parties, including:

    Freeze-dried human rabies vaccine (Vero cells); Inactivated polio vaccine; Haemophilus influenzae type b conjugate vaccine; Japanese encephalitis attenuated live vaccine; Live attenuated mumps vaccine; Freeze-dried Japanese encephalitis inactivated vaccine (Vero cell) recombinant hepatitis B vaccine (CHO cell, Hansenula yeast); Group A and Group C Meningococcal Conjugate Vaccine; ACYW135 Meningococcal Polysaccharide Vaccine; Varicella attenuated live vaccine; Live oral rotavirus vaccine; Inactivated hepatitis a vaccine (human diploid cells).

There are two other immunoglobulins:

    Rabies human immunoglobulin; Hepatitis B human immunoglobulin.

There should be new cases to be announced in the future.

Is it necessary to take the children to Hong Kong for vaccination?

In theory, if family conditions permit, children can be considered for vaccination abroad.

However, there is a problem of convergence between vaccination in different places. For example, it is not to say that the first injection in the Mainland can be directly given the second injection in Hong Kong. Moreover, the vaccinated children are relatively young and may not be able to withstand the ordeal of traveling for a long time.

In addition, don’t choose the service of purchasing vaccines on behalf of others. It is difficult to guarantee the source and the standard in the transportation process. It is difficult to guarantee that the vaccines purchased on behalf of others are not [problem vaccines].

In order to prevent the problem vaccine from being vaccinated, can I not vaccinate my children?

This does more harm than good, At present, vaccination is still the best and most effective means to prevent diseases. Although the problematic vaccine incident has once again aroused public concern about vaccine safety, However, one pole cannot upset a boat. Hepatitis B and measles prevented by the first type of vaccine and chickenpox prevented by the second type of vaccine all pose great threats to children’s health. Vaccination is still the best means to protect health.

After being vaccinated with problematic vaccines, besides failure, what other problems may occur?

The biggest risk of these problematic vaccines is [may fail], resulting in failure to prevent corresponding diseases. In addition, some parents worry that these problematic vaccines may have adverse reactions.

In fact, the common adverse reactions of vaccines include local redness, swelling, heat pain, fever, allergy, etc. Generally, it is relatively mild, and the most serious is the infection caused by live bacteria or viruses in the reduced live vaccine. For example, polio caused by taking polio sugar pills before, but the risk of occurrence is very low. Common adverse reactions are very mild and will not be fatal or disabled. Most of them occur within 24-48 hours after vaccination, and the possibility of recurrence in the later period is very small.

Before, when I was vaccinated with meningococcal vaccine, the doctor said that there was no one type, so I had to be vaccinated with the second type. What should I do now?

Meningococcal vaccine has a variety of dosage forms, some dosage forms do only have the second type of vaccine, there is no first type of vaccine, but it belongs to the second type of vaccine voluntarily vaccinated. If the vaccination site refuses to provide the first type of vaccine, it can be reported to the local disease control department or the health supervision department.

Moreover, not all the second type of meningococcal vaccines are problematic vaccines. At present, the specific flow direction of the problematic vaccine is still not completely clear. After further disclosure of relevant department information, it can be determined whether the vaccine vaccinated by the baby is a problematic vaccine by comparing the vaccination records on the vaccination certificate.

Will there be any problems with the epidemic prevention center of our local community health service station? How? Which epidemic prevention agencies are most likely to have problematic vaccines?

We still call on parents not to impose [presumption of guilt] on various vaccination units, At the same time, we also urge the regulatory authorities to inform the public as soon as possible which vaccination points the problem vaccine finally flows to. At present, the provinces and cities involved in the problem vaccine have already disclosed, and we hope that a more detailed list will be disclosed as soon as possible so that parents can determine whether their children have been vaccinated with the problem vaccine.

If I take my child to get a vaccine, how can I judge whether the vaccine is a problem vaccine? Can the organization be required to show its what certificate?

Parents can understand the scope of the problem vaccine disclosed by the state, and then judge against the vaccine to be vaccinated by their children. If parents still have doubts about this, they can wait for more information to be disclosed before going to vaccinate. At present, there is no direct proof of this type of vaccination unit.

How to judge whether the vaccination is successful? Can the detection of antibodies be confirmed? Which vaccines can detect antibodies?

There is basically no good method to determine whether the vaccination is successful, except hepatitis B vaccine.

In general, By detecting the antibody, it can be determined whether the concentration has been reached to prevent the corresponding disease. However, this test is only used by the health department to monitor the immune effect of the population. In the daily monitoring process, the disease control department will conduct spot checks on the immune effect of the vaccine, draw blood to measure antibody titers, and judge the vaccination effect, such as measles, rubella, whooping cough, hepatitis B and other vaccine antibodies against Class I vaccines, and varicella antibodies against Class II vaccines;

But the problem is:

First of all, not every disease can check antibodies, and many vaccine antibodies can only be checked in the laboratory at present, and do not provide such services. In addition to hepatitis B antibody can be routinely tested, the general public cannot take their children to the CDC to check antibodies including chickenpox, pneumonia, epidemic cerebrospinal meningitis, rabies and other vaccines. This is the case in first-tier cities such as Shanghai and Beijing.

Secondly, even if antibodies do exist, it does not directly mean that they can definitely prevent diseases.

Therefore, in addition to trying to determine the hepatitis B antibody, don’t think about testing other antibodies.

The child has been vaccinated with hepatitis B vaccine for three times before, but when he was two years old, he found that the hepatitis B antibody was negative. Is this caused by the failure of the problematic vaccine?

Children who have been vaccinated but do not have antibodies are not necessarily the failure caused by the problematic vaccine. Due to individual differences, After normal vaccination, there is still a certain possibility that the antibody is negative. Therefore, this is not necessarily caused by the problematic vaccine, or it may be that the vaccination has not been successful. If the child’s antibody shows negative, he can choose to replant a shot.

Therefore, parents are also reminded that their children should be tested for hepatitis B antibody.

If you have been vaccinated before, but find out that hepatitis B antibody is negative, what should you do next?

Although some experts believe that as long as they have been vaccinated, those with few or even negative antibodies do not have immunity, so they think they can not be vaccinated.

Isn’t hepatitis B vaccine a type of vaccine? Why is there hepatitis B vaccine in the report?

Hepatitis B vaccine is divided into two kinds, one is free, is a kind of vaccine, also has different manufacturers to produce hepatitis B vaccine, need to buy at one’s own expense, is a kind of vaccine. Some epidemic prevention centers may provide two kinds at the same time, or only at one’s own expense hepatitis B vaccine.

However, considering that parents are basically very concerned and there is no better judgment index at present, I recommend direct replanting of hepatitis B vaccine, as long as another dose is added.

Since some vaccines cannot be tested for antibodies, can they be replanted directly in case of any accident?

Unless it has been confirmed that the problem vaccine has been vaccinated, routine replanting vaccine is not required.

However, some parents are under great psychological pressure. If they are really not at ease, they can also directly choose an organization that you are at ease for replanting. Or after the case is further clarified, whether to replant the corresponding vaccine will be decided by comparing the vaccination points of the found problems and then comparing the vaccination history of the children.

If parents are still not at ease with the current Class II vaccine, then wait. The delay in this time will not generally affect the effect of the vaccine. It is better to wait until things become clearer and try our best to avoid those problematic vaccines.

In addition, the vaccine management has been relatively strict in the first-tier cities of the formal epidemic prevention center, basically don’t have to worry about the existence of vaccine problems. You can choose the epidemic prevention agencies that you think are reliable enough for vaccination.

Can the pentavalent vaccine still be used? The first shot was given a quintuple vaccine. Should we continue or change to a common vaccine?

According to the information disclosed so far, although the scope of this problem vaccine includes inactivated poliomyelitis vaccine, the pentavalent vaccine is not completely equivalent to inactivated poliomyelitis vaccine and is still two different vaccines, so the pentavalent vaccine can still be vaccinated.

I just got rabies vaccine ten days ago, and I still haven’t got one shot. Will I continue to get it next? How?

It is still necessary to continue to inoculate according to the original dose. The consequences of rabies are serious after the onset of rabies, and it is not recommended to interrupt the immunization program halfway.

My son didn’t eat sugar pills and got polio vaccine. What if he was shot?

Hello, don’t be nervous. First of all, not all the second class of inactivated polio vaccines are problematic vaccines. At present, the specific flow direction of the problematic vaccines is still not completely clear, and the relevant department information can be further disclosed by comparing the vaccination records on the vaccination certificate to determine whether the vaccines they have vaccinated are problematic vaccines.

Vaccines are the most favorable weapon for human beings to fight diseases. However, some media arbitrarily exaggerate the harm of vaccines and mislead everyone to give up vaccination, seemingly avoiding risks, but actually facing greater risks!
