What are the adverse reactions to the Haemophilus influenzae type b vaccine?

Haemophilus influenzae type b is the most common pathogen that causes clinical pediatric infections. Haemophilus influenzae type b and antigens can be combined to develop a relatively new mixed vaccine, which is helpful for people's disease prevention. However, are there any adverse reactions to the Haemophilus influenzae type b vaccine? Let's take a look at the relevant introduction.

Adverse reactions to the Haemophilus influenzae type b vaccine still exist clinically. Relevant medical research states that after vaccination with the Haemophilus influenzae type b vaccine, the vaccinated person must be actively monitored and the symptoms and physical characteristics that occur after the vaccination must be recorded daily.

Within 48 hours after vaccination, the common local symptoms collected include mild redness at the injection site, which can resolve on its own. Other local symptoms reported included mild swelling and pain at the injection site.

Within 48 hours after vaccination, the collected and reported systemic symptoms were mild and resolved on their own. These symptoms include fever, loss of appetite, irritability, vomiting, diarrhea and unusual crying. As with all Haemophilus influenzae type b vaccines, there have been reports of the above-mentioned systemic symptoms occurring when this product is administered simultaneously with other vaccines. Very rare allergic reactions, including anaphylaxis, have been reported.

Because adverse reactions to the Haemophilus influenzae type b vaccine may occur, after vaccination, we must wait until our physical symptoms are relieved before leaving. Even if we don’t feel anything, we have to wait for a while before leaving to observe changes in physical symptoms and respond in time.
