According to the Jiangsu public news channel "News 360", more than 50% of common pneumonia is caused by Streptococcus pneumoniae. The most effective way to deal with pneumonia caused by pneumococcal bacteria is to get vaccinated. The reporter learned from the Jiangsu Vaccination Program and Pneumonia Immunization Prevention Strategy Conference held on January 24 that the world's first dual-carrier 13-valent pneumonia vaccine was officially listed in Jiangsu, which also means that there are more options for preventing childhood pneumonia.
【Infants and young children aged 6 weeks to 5 years old can be vaccinated with longer immunization time】
Autumn and winter are the high incidence of respiratory diseases, and children within 6 years of age have not yet fully developed their immune function and are always facing a huge risk of pneumococcal invasion. Once infected with pneumococcal disease, it is very likely to cause serious sequelae such as mental retardation and paralysis. Experts said that vaccination with 13-valent pneumonia vaccine can protect children from the invasion of the 13 most common and harmful serotypes of serotype pneumococcus, helping children build protective barriers.
Pan Hongxing, director of the Vaccine Clinical Evaluation Institute of the Jiangsu Provincial Center for Disease Control and Prevention, said that after receiving a double-carrier vaccine, the amount of antigen that reaches the cell to produce a cellular immune response will be more, and the amount of antigen of cellular immunity is the most needed by children aged 6 weeks to 5 years.
According to experts, the vaccine uses two carrier proteins to bind to polysaccharides, which is the world's first dual-carrier 13-valent pneumococcal polysaccharide conjugate vaccine. Compared with traditional single-carrier vaccines, the immune effect is better, the immunity duration is longer, and the safety is higher. It is worth mentioning that the dual-carrier 13-valent pneumonia vaccine has a good effect on infants and children aged 6 weeks to 5 years old, and the time limit for vaccination is greatly relaxed compared with similar vaccines.
Pan Hongxing introduced that the age range of domestic vaccines used is slightly longer than the current imported 13-valent pneumonia vaccine, which can cover 5 years old, while the imported ones only start from 6 months old to 1.5 years old. The double-carrier 13-valent pneumonia vaccine procedure is more convenient, starting from the injection, as long as the interval is two months, for example, (the first dose is) 1.5 months old, and the subsequent vaccination is 3.5 months old and 5.5 months old.
Domestic double-vector 13-valent pneumonia vaccine immunization program: 4 doses for infants aged 6 weeks to 6 months, 3 doses for infants aged 7 to 11 months, 2 doses for children aged 12 to 23 months, and 1 dose for children aged 2 to 5 years.
【Priced at 458 yuan per dose Five cities such as Xuzhou, Huai'an and Suzhou have been approved】
The price of the domestic dual-carrier 13-valent pneumonia vaccine is 458 yuan / dose, which is more than 30% cheaper than the imported vaccine, and the supply is more abundant. At present, this vaccine has been approved in five cities of Xuzhou, Huai'an, Yancheng, Suzhou and Changzhou in Jiangsu Province, and it is recommended that children of appropriate age be vaccinated as soon as possible.
