Is it necessary to get the Haemophilus influenzae type b vaccine?

When it comes to the Haemophilus influenzae type b vaccine, perhaps many people don’t know about it, because we generally don’t come into contact with this Haemophilus influenzae type b vaccine in our daily lives. In fact, from the name of the Haemophilus influenzae type b vaccine, we can roughly guess that this Haemophilus influenzae type b vaccine is mainly targeted at Haemophilus influenzae type b and prevents human body from being infected with Haemophilus influenzae type b. So, is it necessary to get the Haemophilus influenzae type b vaccine?

Vaccine injections are generally given to prevent corresponding diseases, and the same is true for the Haemophilus influenzae type b vaccine. However, most people have no knowledge of the Haemophilus influenzae type b vaccine, and some people have never even heard of the name of the Haemophilus influenzae type b vaccine. In fact, this Haemophilus influenzae type b vaccine is mainly injected into infants and young children. So let’s talk about whether it is necessary to get the Haemophilus influenzae type b vaccine.

It is necessary to get the vaccine because infants and young children under 2 years old are most susceptible to this disease, which can mainly cause meningitis, pneumonia, etc. Although it can be treated with medication, if not treated in time, it may leave serious sequelae because it damages the brain.

The Haemophilus influenzae type b conjugate vaccine is made by covalently combining purified Haemophilus influenzae type b capsular polysaccharide with tetanus toxoid. It is a colorless, transparent liquid, contains preservatives, and does not contain foreign matter or clots. After vaccination, the body can produce a humoral immune response. In a multicenter clinical study (n=903) comparing the efficacy of this product and freeze-dried Haemophilus influenzae type b vaccine, 678 healthy American infants and young children aged 2-6 months received 1,699 doses of this product. Most of the recipients also received DPT (diphtheria, pertussis and tetanus) and OPV (oral polio vaccine) at the same time. The recipients tolerated the two different dosage forms of Haemophilus influenzae type b vaccine well, and no serious vaccine-related adverse reactions were found.

Within three days after the first vaccination with this product, the most common adverse reactions (incidence > 1%, regardless of the cause, except those listed in Table 1) are, in descending order of incidence: irritability, drowsiness, pain at the injection site, erythema at the injection site (vertical ≤ 2.5 cm, see Table 1), mass/nodule at the injection site (diameter ≤ 2.5 cm, see Table 1), abnormally loud crying, prolonged crying (> 4 hours), diarrhea, vomiting, crying, pain, otitis media, rash and upper respiratory tract infection.

Through the detailed introduction above, we can actually know that the so-called Haemophilus influenzae type b vaccine is mainly for infants and young children under two years old, so the Haemophilus influenzae type b vaccine is very necessary. Infants and young children are very weak, and Haemophilus influenzae type b often causes diseases such as meningitis and pneumonia. They can be effectively prevented by injecting the Haemophilus influenzae type b vaccine.
