The 13-valent pneumonia vaccine is intended for infants and children between the ages of 6 weeks and 15 months, so the vaccination should be completed within 15 months of age. The 13-valent pneumonia vaccine, known as 13-valent Streptococcus pneumoniae polysaccharide conjugate vaccine, is used to prevent pneumonia, meningitis, otitis media and sepsis caused by Streptococcus pneumoniae infection. The vaccine requires a total of four doses, one at 2 months, 4 months and 6 months of age for the primary immunization and another at 12-15 months of age for the booster immunization. The first dose can be given at 6 weeks of age at the earliest and at 6 months of age at the latest, with subsequent doses given at intervals of 4-8 weeks each. However, infants and children who have received the 13-valent pneumonia vaccine are not completely and absolutely insured. They still need to pay attention to healthy eating habits, balanced nutrition, and adhere to moderate exercise in order to enhance their physical fitness and prevent the occurrence of pneumonia.
