Question and Answer on Vaccination

1. Is there any difference between free vaccines and imported charged vaccines in what?

There may be differences and cannot be generalized.

The factory standard of some domestic vaccines will be higher than the national standard, while some imported vaccines may just meet the national standard.

However, both imported vaccines and domestic vaccines have to pass the quality inspection of the national drug control department before they are put on the market, so the quality can meet the standards and their effectiveness and safety are guaranteed.

2. Will rabies vaccination affect sperm motility?

[Allergic Constitution] is a folk saying and a vague concept in medicine.

The national standard for vaccine production and verification is higher than that of ordinary drugs, and the safety of vaccines is also better than that of ordinary drugs, but it does not rule out that a very small number of people will be allergic to the vaccine itself or trace impurities in it.

For children who are allergic to eggs, foods containing egg ingredients or have experienced anaphylactic shock in the past, the doctor who carried out the vaccination should be informed before vaccination, and the vaccination should be carried out after comprehensive evaluation.

6. Do pregnant women need to be vaccinated against what?

According to the recommendations of the World Health Organization, it is best to be vaccinated with rubella-containing vaccine before pregnancy (because rubella during pregnancy may cause infant malformation), but it is recommended to avoid pregnancy within 3 months after vaccination.

Vaccines such as hepatitis B need to be vaccinated according to the specific situation.

7. Does it matter if the child has low fever after vaccination?

Some children will have low fever after vaccination, fever generally lasts for 1-2 days, and then will drop down.

What suits you is the best.

The effect and safety of the combined seedling are guaranteed as well as those of the single seedling.

What you said is the first type of vaccine, which refers to the vaccine provided by the government to citizens free of charge and that citizens should be vaccinated in accordance with the regulations of the government. The purpose of vaccination is to prepare children’s immune system for diseases and protect children from some diseases. If there is no vaccination, all should be vaccinated.

12. The age is beyond the age range that the vaccine should be vaccinated. Do you need to be vaccinated again?

This problem is relatively professional and it is difficult to generalize. Specific analysis is needed between different vaccines.

(1) For hepatitis B vaccine, those who are over 6 months old but are at risk of infection need to be vaccinated.

(2) For rotavirus vaccine, adults do not need to be vaccinated.

(3) For measles vaccine, even adults, if they have not been vaccinated in the past, replanting is strongly recommended.

Almost all vaccines depend on the situation, the epidemic situation of the disease, the consequences of the disease and the incidence probability of the age group.

13. The second dose of hepatitis B vaccine for children is when they are 2 months old. Will this affect the effect?

Strictly speaking, the second dose of hepatitis B vaccine should be vaccinated at the age of 1 month, but if it is missed, it will not have a great impact, and the following third dose of hepatitis B vaccine will be postponed.

14. The child has been vaccinated with hepatitis B vaccine in the whole process. Now he is almost 4 years old. Is it necessary to strengthen the injection?

Whether it is necessary to strengthen vaccination should be considered from two angles:

(1) Whether people who are in close contact with children have carriers of hepatitis B virus;

(2) Whether the child has enough hepatitis B antibody (which can be determined by [hepatitis B two-and-a-half] examination).

When people in close contact have hepatitis B virus carriers or hepatitis B antibody is insufficient, they should consider strengthening vaccination.

15. After the mother of hepatitis B carrier gives birth, should the child be vaccinated how?

For babies of hepatitis B carriers, it is best to inject 100U of hepatitis B immunoglobulin (vaccination is also required) within 12 hours after birth. You can also inoculate a dose of hepatitis B immunoglobulin after birth, and then start inoculating hepatitis B vaccine at the same time after inoculating the second dose of immunoglobulin in the first month.

16. Can children who play for a week be vaccinated against influenza? Is it more appropriate to vaccinate in what?

One-week-old children are not recommended to be vaccinated against influenza, and should be vaccinated at least after the child is 6 months old.

1-2 months before influenza epidemic is the best time to vaccinate influenza vaccine. In our country, influenza epidemic is mainly concentrated in November to March of the following year, so the vaccination time is also arranged in September to November. In the area south of the Yangtze River, because the weather is cold late, so the vaccination time is generally concentrated in October to December.

17. How should Haemophilus influenzae vaccine (Hib) be vaccinated?

Haemophilus influenzae vaccine (Hib) vaccination procedure is more complicated, the most common procedure: before 6 months of age, 3 doses at intervals of 1 ~ 2 months, after reaching 1 year old (usually 18 months old), 1 dose again. For other vaccination methods, please refer to the instructions.

18. Is it necessary to take optional vaccines at one’s own expense, such as influenza vaccines?

From the perspective of disease prevention, vaccination at one’s own expense can obtain wider protection and is worth vaccination.

No matter vaccination at one’s own expense or free vaccine, the corresponding diseases can be prevented. Most developed countries have already achieved free vaccination of all vaccines or paid for by medical insurance. China is a developing country and cannot achieve free vaccination for the time being. Therefore, it is divided into free vaccination and self-paid vaccination.

19. Does rotavirus vaccine need to be vaccinated every year?

Rotavirus vaccine is the second type of vaccine and belongs to voluntary vaccination. The vaccination procedure is: under 3 years old, vaccinated once a year.

20. When the baby takes polio vaccine orally, it spreads a little. Will it affect the prevention effect?

Scattering part will not affect the prevention effect, don’t worry.

21. Before vaccination, the baby used immunoglobulin for treatment. Will this have adverse consequences for what?

The current research has not found that the simultaneous use of immunoglobulin and vaccine will have serious adverse consequences. If the baby has no obvious abnormalities at present, the possibility of adverse reactions in the future is extremely low, so there is no need to worry too much.

22. What should a child do if he misses a vaccination due to illness?

Don’t worry too much, all missed vaccines can be postponed to the next month. Note that the vaccination is not according to the original schedule.

23. Does pentavalent vaccine have the advantages of what?

Quintuple vaccine will DPT, Haemophilus influenzae, poliomyelitis vaccine together for vaccination, the most obvious advantages are less vaccination times, less needles for children, and less trips for adults. The disadvantage is that at one’s own expense, the relative price is relatively high.

24. Will the adverse reactions of two-month-old children vaccinated with pentavaccine be very large?

At present, there is no phenomenon that [two-month-old children react greatly after being vaccinated with pentavalent vaccine].

Any vaccine must go through a large number of human tests before it is put on the market, and it will only be put on the market if it is confirmed to be safe. As a vaccine used by all countries in the world, the safety of pentavalent vaccine has been fully affirmed.

25. A two-month-old child has received a shot of polio vaccine. Can he still receive a quintuple vaccine?

Yes, it can be replaced by five doses at the time of the second shot, but after the final three doses and five doses, DPT and Haemophilus influenzae vaccines (Hib) need to be supplemented.

26. Why are pentavalent vaccines and Lanjunjing often out of stock and unable to be vaccinated?

The reasons for the shortage of the two are fundamentally different. The shortage of pentavalent vaccines is the reason why the company’s production capacity is limited. It produces too little and sells too fast.

However, Lanjunjing is not a vaccine. On January 22, 2016, the State Food and Drug Administration stopped the import of Lanjunjing. Since then, there may not be any more [Lanjunjing] in China.

27. After the child was vaccinated with BCG vaccine, there was no [scar] on his arm. Does this mean that the vaccination was unsuccessful?

After most children are vaccinated with BCG vaccine, a scar will appear at the place (arm) where they are vaccinated, commonly known as [scar].

However, the existence and size of the [card scar] are not necessarily related to the success and effect of the vaccination, as long as it is confirmed that the vaccination has been carried out.

28. After the child was vaccinated with BCG vaccine, a knot in one’s heart appeared in the place where he was vaccinated. There was pus in it. What is going on?

This is commonly known as [scar]. The scar left by BCG vaccination can be seen on your left arm or on the left arm of the people around you.

At the beginning of inoculation, don’t worry too much if there is pus in pimples. At ordinary times, be careful not to break it. If it is accidentally broken, wipe off the pus with dry cotton swabs.

Generally, this knot in one’s heart will dry and scab will heal in 8 ~ 12 weeks. However, if fever and lymph node enlargement occur all the time during this period, it is recommended to contact the vaccination unit and be hospitalized.

29. Is there any difference between a polio vaccine at one’s own expense and a free one? Is imported polio vaccine better?

Free is attenuated polio vaccine, imported at their own expense is mostly inactivated polio vaccine.

Judging whether a vaccine is good or bad depends on at least three indicators: safety, effectiveness and price. Each family has different sensitivity to these three indicators, so it cannot be generalized.

However, no matter imported or domestically produced, each batch of vaccines can only be put on the market after passing the appraisal by the authoritative department of our country, and the safety is guaranteed.

In addition, various cities in our country are gradually replacing attenuated polio vaccine with inactivated polio vaccine. I believe that we will be free to vaccinate inactivated polio in the future.

30. When the third shot of inactivated polio vaccine was given, there was a shortage of drugs locally. It has been more than 60 days since the interval. What should I do now?

Under normal circumstances, the interval between polio vaccines is about 30 days, and the interval of more than 60 days is relatively long. Although the previous shots will not be given in vain after waiting, the use of oral attenuated vaccines is also an option.

31. How long can the baby take the vaccine after suffering from pneumonia?

The specific time depends on the specific situation and there is no uniform standard. After the general pneumonia is cured and the drug is stopped, the child can be vaccinated when he recovers to a healthy level.

32. Is it necessary for people who have had pneumonia to receive pneumonia vaccine?

At present, the full name of pneumonia vaccine still widely used in China is [23-valent pneumococcal polysaccharide vaccine], which prevents and treats diseases caused by 23 kinds of pneumococcal (23 kinds of bacteria), such as pneumonia, encephalitis, otitis media, etc. (not only pneumonia this time) caused by pneumococcus. Therefore, even if you have pneumonia, you can still prevent diseases by taking pneumonia vaccine again.

33. The child is three years old, which kind of pneumonia vaccine should he take?

Children over the age of two can be directly vaccinated with [23-valent pneumonia vaccine].

34. What is the safety of domestic 23-valent pneumonia vaccine?

Domestic 23-valent vaccines are as safe as imported 23-valent vaccines.

No matter imported or domestically produced, each batch of vaccines can only be put on the market after passing the appraisal by the authoritative department of our country, and the safety is guaranteed.

35. Why is the 7-valent vaccine for pneumonia stopped at present? Do you have a price of 13?

Not [seven-price] stop using but stop import. Because its import license time has nearly expired, so stop import. So don’t struggle with whether there is any need to play. At present, the 13-price pneumonia vaccine with higher cost performance is being examined and approved. After handling the relevant procedures, it can enter the market.
