Does the baby have pneumonia and need pneumonia vaccine?

Pneumonia vaccine refers to 23-valent pneumococcal polysaccharide vaccine, which is suitable for children under two years of age with poor resistance and easy to be repeatedly infected with pneumonia. The vaccine can effectively resist Streptococcus pneumoniae infection. If the baby has pneumonia caused by Streptococcus pneumoniae before, it is not necessary to vaccinate in a short time.
