Baby's vaccinations delayed for 7 months

Babies need to receive different types of vaccines every month in the first year after birth. However, due to various reasons, it is possible that the vaccination time may be delayed. For example, if a child is sick or has other health problems, vaccination is not allowed. Therefore, the vaccination situation should be decided based on the baby's physical condition. What should I do if the baby's vaccination is delayed for 7 months?

If I get the vaccine late, do I have to start over?

The general principle for booster shots for routine vaccinations is: get as many shots as you missed, no need to start over.

The general principle for booster shots is: give as many shots as you missed, and there is no need to start over. Only a very small number of vaccines need to be re-administered. For example, for a typhoid vaccine used in the United States, some experts have suggested that if the regular doses cannot be completed within one cycle, revaccination is required.

Are there some vaccines that can be given after a certain age?

Yes, indeed. For example, the rotavirus vaccine is not given to people over 4 years old, the Haemophilus influenzae vaccine is not given to people over 5 years old, and the hand, foot and mouth disease vaccine is not given to people over 5 years old.

Does vaccination guarantee that you will not get any infectious diseases?

Vaccination is the most economical and effective means to prevent and control infectious diseases, but its success rate is not 100%. The protection rate of most vaccines is >80%. Due to special reasons of the individual vaccine recipients, such as low immune response capacity, immune failure after vaccination may occur. However, a large number of studies have shown that even if the disease occurs after vaccination, the clinical manifestations after the disease are much milder than those who are not vaccinated.

Which of the self-paid vaccines are recommended for babies?

All vaccines can prevent diseases. The only difference between self-paid vaccines is that the government does not pay for them currently, so individuals have to pay for them.

Some of the diseases that self-paid vaccines prevent are very serious, while others are not so serious. The importance of vaccines is ranked from high to low according to the severity of the disease.

1. Haemophilus influenzae vaccine (including quadruple vaccine and pentavalent vaccine) and pneumococcal conjugate vaccine should be administered starting at 2 months of age, with a total of 4 doses within 2 years of age.

2. Influenza vaccine: Starts from 6 months of age (2 doses in the first year, 1 dose each year thereafter), and should be administered from September to October every year.

3. Hand, foot and mouth disease vaccine: 2 doses are given starting from 6 months of age, with an interval of 1 month. It can be given before 5 years of age, but it should be given earlier.

4. Varicella vaccine: it is recommended to receive one dose each at 12 months and 4 years of age. The shortest interval between the two doses can be 3 months.

5. AC meningococcal conjugate vaccine and quadrivalent polysaccharide vaccine. AC meningococcal conjugate vaccine can be used to replace the free group A meningococcal polysaccharide vaccine at 6 and 9 months of age; quadrivalent meningococcal polysaccharide vaccine can be used to replace the free AC polysaccharide vaccine at 3 and 6 years of age.

6. Rotavirus vaccine: 1 dose per year starting from 2 months of age until 4 years of age.

7. Cholera vaccine: for children aged 2 to 6 years, 3 doses are taken within 1 month. However, the incidence of diseases prevented by cholera vaccines is extremely low, so it is generally not necessary to take them.
