Is varicella vaccine attenuated or inactivated, and what is the difference between imported and dome

The chickenpox vaccine is a live attenuated vaccine, and now there are no imported ones, only domestic ones, and several companies are producing them.

Hello, for your question, I try to answer your questions: in the national immunization program of a type of vaccine, chickenpox vaccine is not among them, therefore, can be regarded as not compulsory vaccination, but chickenpox is an acute infectious disease, especially among the group of children spread and infectious is very strong, often heard and see the kindergarten or primary school group disease, if the sick child is not properly cared for, secondary infection is also very harmful to the body, In particular, chickenpox will remain in the nerve roots for a long time after the disease, and after a few years, the trigger will cause herpes zoster, which is painful and difficult to heal, and will cause great physical and mental harm to the patient. Therefore, although the country has not yet included this vaccine in the management of a class of vaccines, families with conditions still hope to vaccinate their children with this vaccine.

In reality, I occasionally heard that some children have been vaccinated, but still have chickenpox, the note on this is: the effectiveness rate of the vaccine is not guaranteed to be 100%, for specific constitution, children with slow immune response, the vaccination process is not standardized, etc., may reduce the titer of the vaccine, in addition, if the child has had direct or indirect contact with the patient before vaccination, is in the infection and incubation period of the disease, the vaccination of the vaccine will induce the disease to quickly enter the clinical symptom period. In addition, chickenpox can be immunized for life, so if you have had chickenpox when you are a child, then you will not get sick if you come into contact with the patient in the future, and if the child has had close contact with him during the intense period of chickenpox (such as sharing a table, playing together, studying, eating, etc.) but does not get sick, and your child is sure that he has not had chickenpox before, then it can also be assumed that your child may have acquired immunity, so he will not get sick.

However, the credibility of this inference is not strong, and the real thing to confirm should be to do immune antibody testing for children, but this kind of monitoring is generally done by the Centers for Disease Control and Prevention, and it seems that it is not for monomers.

The last question is, which vaccine should I get? At present, there are two kinds of chickenpox vaccines used in most areas of China, domestic and imported, it should be said with certainty that although the price of the two vaccines is different, the immune effect after vaccination is the same, but China's vaccine is more stringent because of its strong activity, so the requirements for the cold chain are stricter, if there is a problem in a certain link, then the potency of the vaccine is not guaranteed, and this, our parents can not confirm. Therefore, if you want to vaccinate your child against chickenpox, I personally recommend getting the imported Vicomon chickenpox vaccine, which feels safer and more reliable.

Must fight. If there are conditions, it will be imported, in fact, the domestic one has been produced for so many years, and there should be no problem.

Must fight. If there are conditions, they will be imported, but in fact, the same is true for domestic ones.

Three points are different:

First, in terms of the vaccine itself, the concentration of imports should be high. The effect will be better. Imports are 330, domestic is 160

Second, in terms of breakthrough cases (that is, cases of chickenpox that still develop after vaccination), imports should be less than half due to their high concentration.

Third, the issue of sales compensation, at the time of vaccination, if you still have chickenpox 31 days after receiving the imported chickenpox "Wei Ke Meng", you can refund the full amount of the vaccine 330At present, domestic production basically does not have this commitment.

None of the doctors knew to me because I used to be a professional vaccine representative for this imported vaccine.

In my personal opinion: it's okay to play domestic, reason.

One: It has the effect of preventing chickenpox, and it is good to import it, but the domestic one can also prevent chickenpox disease, out of patriotism, I will choose the domestic one.

Two: ** aspects are too different.

Three: As long as you are vaccinated, even if you have chickenpox again, its symptoms are very mild.
