13-valent pneumonia vaccine is an active immunization vaccine for infants and children under 2 years of age and is effective in preventing pneumonia caused by Streptococcus pneumoniae infection. Infants and young children are particularly susceptible to pneumonia due to their poor health and low immunity, and the main causative agent in infant pneumonia is Streptococcus pneumoniae. Therefore, for children with recurrent respiratory infections and poor immunity, basic immunization with this vaccine can be administered at 2 months, 4 months, and 6 months of age, respectively, with booster immunization at 12-15 months of age. During the high season of influenza and pneumonia, do not take your baby to crowded places, keep indoor ventilation, give your baby more water and eat more food with high quality protein, all of which can improve your baby’s organism’s ability to resist diseases.
