The mainland’s 13-price pneumonia vaccine is hard to find. Experts suggest rational vaccination without panic
Xinhua News Agency, Shanghai, August 16th Question: The mainland’s 13-price pneumonia vaccine is hard to find. Experts suggest rational vaccination without panic
Xinhua News Agency reporters Qiu Yi and Gong Wen
Ms. Chen of Shanghai recently "grabbed" the last 13-price pneumonia vaccine in a community health service center far from home. In contrast, Mr. Zhang has been worried about finding such a vaccine for a long time.
According to industry insiders, although the number of 13-valent pneumonia vaccine entering Shanghai is limited, if the baby is not vaccinated, parents need not panic. On the one hand, they should take daily protection. On the other hand, people who are weak after 2 years old can choose to vaccinate 23-valent pneumonia vaccine.
13-price pneumonia vaccine is in short supply.
Mr. Zhang told reporters that in the past, the baby had to go to Hong Kong for 13 yuan. With the introduction of the mainland and landing in Shanghai in July, it was a very happy thing for parents, but I didn’t expect that it had become hard to find a needle when taking the baby to the community health center recently. "We even made an appointment at the foreign-funded Baihui Medical Center, which costs 2,300 yuan, which is much more expensive than the community health service center’s 700 yuan, but there is no vaccine there now."
The reporter asked a community health service center in Putuo District about the supply of 13-valent pneumonia vaccine, and the result was that "the second-class vaccines are generally out of stock this year, and the specific reasons are not very clear, because the second-class vaccines are now uniformly determined by the district CDC." The so-called second-class vaccine refers to other vaccines that are inoculated by citizens at their own expense and voluntarily compared with the first-class vaccine provided by the government to citizens free of charge.
Zhang Yuyan, director of Shanghai Putuo District Center for Disease Control and Prevention, said that at present, the vaccine is booked by the community health service center to the district CDC according to its own needs, and then purchased from the enterprise by the district CDC and then sent to each inoculation point. Because the vaccine needs to be approved by the relevant state departments, it is unclear about the specific cycle length. Some of them are very fast, some have to wait for several months, and the other five-vaccine for children has been out of stock for several months.
According to china food and drug administration, batch issuance of vaccines is one of the six functions of national vaccine supervision required by WHO. In the national vaccine management system, batch issuance is the last pass before vaccines are put on the market to ensure the safety and effectiveness of vaccines. On January 1, 2006, the regulatory authorities issued batches of all listed vaccines, that is, the system of mandatory inspection and audit for each batch of products when they are listed or imported. If the inspection fails or the audit is not approved, it shall not be listed or imported.
Why is the small vaccine so popular?
13-valent pneumonia vaccine, the full name of "13-valent pneumococcal polysaccharide conjugate vaccine", is used to help infants aged 6 weeks to 15 months to prevent related invasive diseases caused by 13 pneumococcal serotypes, including bacteremia pneumonia, meningitis, septicemia and bacteremia.
The healthy growth of children is related to every family and even the whole society. Among vaccine-preventable diseases, pneumococcal disease is one of the important causes of death in children under 5 years old. At present, antibiotics are still the main method to treat invasive pneumococcal diseases, but antibiotics that used to be effective against pneumococcal diseases are now facing more and more serious drug resistance.
In April this year, Pfizer, a global pharmaceutical giant, held a 13-price pneumonia vaccine listing in Beijing, and many cities were able to vaccinate one after another. For many families, it was a long drought. It is worth mentioning that this vaccine is the only pneumococcal polysaccharide conjugate vaccine that can be used for infants aged 6 weeks to 15 months in China. In addition, this vaccine has been included in the national immunization plan by more than 100 countries and regions around the world.
"Due to the strong demand for 13-valent pneumonia vaccine vaccination at present, the Shanghai area is temporarily in short supply. We are actively coordinating and striving to meet everyone’s needs as soon as possible. " Pfizer responded.
Experts suggest that there is no need to panic if you can’t get the vaccine.
According to the vaccination schedule of 13-valent pneumonia vaccine, the first step is basic immunization. One to three doses are inoculated within 6 weeks to 6 months, and the interval between each dose is 4 to 8 weeks. The second step is to strengthen immunization and inoculate 1 dose within 12 to 15 months of age.
In view of many parents’ anxiety that the baby missed the vaccination time due to the shortage of vaccines, Zhang Yuyan suggested not to worry too much. If it is really necessary, the baby can choose to be vaccinated with 23-valent pneumonia vaccine after the baby is 2 years old. In addition, vaccination with 13-valent pneumonia vaccine can prevent the related invasive diseases caused by 13 serotypes it covers, but if it is pneumonia or diseases caused by other reasons, vaccination with this vaccine will not play a role.
Compared with the trivalent pneumonia vaccine, the trivalent pneumonia vaccine covers 23 serotypes of Streptococcus pneumoniae. Children under 2 years old are not perfect in their own immune system, so it is not easy to produce antibodies to polysaccharide antigens. Therefore, the vaccine is only suitable for people over 2 years old who are susceptible to diseases (such as children, patients with basic diseases and the elderly).
Hu Jiayu, director of the Monitoring and Evaluation Department of Vaccine Preventable Diseases of the Institute of Immunization of the Shanghai Center for Disease Control and Prevention, said that vaccination can greatly reduce the risk of contracting pneumonia and other diseases, but it does not mean that you can sit back and relax once and for all. As parents, when choosing vaccination for their babies, they should make a rational decision according to the children’s own physique, the risk of infection and the family’s economic affordability.
"Explosive" pneumonia vaccine can’t hit? Knowing common sense is more calm.
Thirteen-valent pneumococcal polysaccharide conjugate vaccine is a self-funded vaccination project, but it is still in short supply, and even in Shanghai and other places, it is "finished" soon after listing. What is the function of the 13-valent pneumonia vaccine? Is there any "remedy" plan if the child misses the appropriate age of the vaccine? Let’s see what the experts say. >>
The 13-valent pneumococcal polysaccharide combined vaccine ushered in the first shot in many places.
Thirteen-valent pneumococcal polysaccharide conjugate vaccine which can be used for infants has been inoculated in Kunming, Xi ‘an, Shenyang and Fuzhou since March 23rd. Ceng Guang, honorary chairman of the Public Health Branch of the Chinese Medical Association, said that under the guidance of the working ideology of continuously optimizing the prevention and control strategies of major diseases and improving the level of major and basic public health services, the listing of trivalent pneumococcal polysaccharide combined vaccine is of great significance to protect infants from the serotype invasive pneumococcal diseases. >>
