When should the 13-valent vaccine be started, in terms of months?
In clinical practice, the 13-valent vaccine refers to the 13-valent pneumococcal polysaccharide conjugate vaccine. It is generally administered as one dose at 2, 4, and 6 months after birth, with booster doses given at 12 and 15 months for optimal effectiveness. The details are as follows:
The 13-valent pneumococcal polysaccharide conjugate vaccine can prevent infections caused by 13 types of Streptococcus pneumoniae, including meningitis, bacteremic pneumonia, sepsis, and other diseases. It is used to prevent pneumococcal infections in infants and young children aged 6 weeks to 15 months. Typically, primary immunization is required at 2, 4, and 6 months of age, followed by booster doses at 12 and 15 months. After vaccination, long-lasting protective antibodies are produced in the body.
Some children may have allergic reactions or other adverse responses to the 13-valent pneumococcal polysaccharide conjugate vaccine; therefore, professional medical advice should be followed before vaccination.
