Is it necessary to administer the 13-valent pneumococcal vaccine after 4 months of age?

Generally, it is recommended to administer the 13-valent pneumococcal vaccine to children over 4 months of age. The detailed explanation is as follows:

The 13-valent pneumococcal vaccine is primarily used to prevent infections caused by 13 serotypes of Streptococcus pneumoniae, including diseases such as pneumonia, meningitis, otitis media, and sepsis. For children over 4 months of age who have not completed the primary immunization series, receiving the 13-valent pneumococcal vaccine remains necessary. Even if the child has passed the standard age for initial vaccination, catch-up doses of the vaccine can still provide effective protection against pneumococcal invasive diseases.

After vaccination, some adverse reactions may occur, such as redness or swelling at the injection site. The area can be disinfected with iodophor. Water contact and pressure on the injection site should be avoided shortly after vaccination to promote healing.

Parents should consult a healthcare professional and make appropriate decisions based on their child's individual circumstances. Additionally, parents should encourage good personal hygiene practices in children, such as frequent handwashing and avoiding contact with sick individuals, which help prevent pneumococcal infections.
