Since March 23, the long-anticipated 13-valent pneumococcal conjugate vaccines, which can be used for infants, have been vaccinated in Wuhua District of Kunming City. The 13-valent vaccines can help prevent devastating diseases caused by 13 pneumococcal pneumonias such as bacteremia pneumonia, meningitis, septicemia and otitis media for infants from 6 weeks to 15 months old.
Among all vaccine-preventable diseases, pneumococcal diseases are the major causes for deaths of children under five years old. Latest study shows that treatment with antibiotics has been affected by the increasingly serious drug resistance. Therefore, getting children to be immune to pneumococcus with early vaccination has been considered as the most economical and effective measure for prevention of devastating pneumococcal diseases. This measure has been widely recognized and strongly recommended by pediatricians.
The 13-valent vaccines available now are categorized as Class Two and can be vaccinated on a voluntary basis. Infants will receive three basic immunizations when they are two, four and six months old, and one booster immunization when they are 12 to 15 months old. The total four immunizations should be implemented within one year.
It is reported that six additional serotypes have been added to the 13-valent vaccines, compared with the 7-valent vaccines, with only seven serotypes. The vaccine coverage has been increased from 70% to 80%, which will reduce the prevalence of the diseases for infants who have vaccinated.
