Hib Vaccine Options for Your Baby's Immunization - Pediatrics

Share to:

What can you tell me about the prevention vaccine for Haemophilus influenzae type b (Hib)?


When the baby was over three months old, they received the first dose of the Diphtheria, Pertussis, and Tetanus (DPT) combination vaccine.
At over six months, they received the second dose of the DPT combination vaccine.
At over ten months, they received the third dose of the DPT combination vaccine along with the Haemophilus influenzae type b (Hib) vaccine (four-in-one).
Now that the baby is one year and eight months old, should they receive the DPT combination vaccine, the four-in-one, the five-in-one, or should the vaccines be administered separately? What is the recommended schedule to ensure effective prevention of Haemophilus influenzae type b? Note: The cost for the Hib vaccine is 600 NTD, the DPT combination vaccine is 400 NTD, and the five-in-one vaccine is 1200 NTD.
The local health center does not offer the four-in-one vaccine.

Dr. Xiao Kaiwen reply Pediatrics


To develop immunity (antibodies) against Haemophilus influenzae type b (Hib), children over one year of age must receive one dose of the Hib vaccine, regardless of whether they received the primary series before one year of age.
The Hib vaccine can be administered in combination with the DTaP (diphtheria, tetanus, and pertussis) vaccine, forming a combination vaccine (often referred to as a four-in-one vaccine), so there is no need to give separate injections, which would cause additional discomfort for the child.
Therefore, if you want your child to have immunity (antibodies) against Hib, please ensure they receive the four-in-one vaccine (the five-in-one vaccine simply refers to the distinction between oral or injectable polio vaccines and is unrelated to Hib).

When it comes to immunizing your child against Haemophilus influenzae type b (Hib), it's essential to understand the recommended vaccination schedule and the options available. Given that your baby has already received several vaccinations, including the DTaP (diphtheria, tetanus, and pertussis) and Hib vaccines, let's clarify the next steps for immunization.


Understanding Hib Vaccination
The Hib vaccine is crucial for preventing serious infections caused by the Hib bacteria, which can lead to conditions such as meningitis, pneumonia, and epiglottitis. The vaccination schedule for Hib typically involves a series of doses:
1. For infants under 6 months: The standard schedule includes three doses at 2, 4, and 6 months, followed by a booster at 12-15 months.

2. For infants aged 7-11 months: The schedule usually consists of two doses given 2 months apart, followed by a booster at 12-15 months.

3. For children aged 12-14 months: They receive two doses spaced 2 months apart, with no additional doses needed after 15 months.


Current Situation for Your Child
Since your child is currently 1 year and 8 months old, they should have received the necessary doses of the Hib vaccine by now. If your child received the Hib vaccine as part of the four-in-one (DTaP + Hib) combination at 10 months, they would have completed the primary series. The booster dose is typically given between 12-15 months, but since your child is now older, they may not need another Hib vaccine unless there are specific health concerns or if the healthcare provider recommends it.


Options for Future Vaccinations
Now, regarding your question about whether to administer the three-in-one, four-in-one, or five-in-one vaccines, here are some considerations:
1. Combination Vaccines: Combination vaccines like the five-in-one (which includes DTaP, Hib, and IPV) can be convenient as they reduce the number of injections your child needs. If your child has not yet received a five-in-one vaccine, this could be a good option to ensure they are fully protected against multiple diseases in one shot.

2. Separate Vaccinations: If your local health clinic does not offer the four-in-one vaccine, you may need to consider getting the vaccinations separately. This could mean administering the Hib vaccine separately from the DTaP or other vaccines. However, this approach may require more visits to the clinic.

3. Consult Your Pediatrician: It is crucial to discuss your child's vaccination history and current health status with your pediatrician. They can provide personalized recommendations based on your child's immunization records and any local health guidelines.


Cost Considerations
You mentioned the costs associated with the Hib vaccine and the combination vaccines. While the Hib vaccine is relatively inexpensive, the five-in-one vaccine may seem costly. However, consider the long-term benefits of preventing serious illnesses, which can be far more expensive and detrimental to your child's health.


Conclusion
In summary, your child should be up to date with their Hib vaccinations if they received the appropriate doses at the correct ages. For future vaccinations, consider the convenience of combination vaccines, but always consult with your healthcare provider to ensure the best approach for your child's health. Vaccination is a critical part of protecting your child from preventable diseases, and staying informed about their immunization schedule is essential for their well-being.
