Frequently Asked Questions about Pneumonia Vaccine 1. What is the difference between the 23-valent pneumonia vaccine and the 13-valent pneumonia vaccine? The 23-valent pneumonia vaccine is a polysaccharide vaccine. The immune response of children under 2 years old to polysaccharide antigens is relatively weak, and the 23-valent vaccine cannot protect them.
The 13-valent pneumonia vaccine is a polysaccharide-protein conjugated vaccine. It has a good effect in stimulating the production of antibodies in infants and young children. Children under 2 years old can also produce good antibody responses. It can produce immune memory and has long-lasting protection. It is recommended to vaccinate the domestic 13-valent pneumonia vaccine.
Therefore, currently, the only pneumonia vaccine suitable for infants under 2 years old in my country is the 13-valent pneumonia vaccine.
In view of its preventive effect and significance against pneumococcal diseases, it has also become one of the "leaders" in the vaccine industry.
2. Do healthy children over 2 years old who have received the 23-price vaccine need to receive another 13-price vaccine? If the child is under 6 years old, healthy children who have received the 23-price pneumonia vaccine can receive another dose of the 13-price pneumonia vaccine and the 23-price pneumonia vaccine.
The interval between the price and the 13th price is at least 8 weeks.
.
3. After children have received 4 injections of 13-price pneumonia vaccine, do they still need to receive 23-price vaccine? Healthy children do not need to receive 23-price vaccine after receiving 4 injections of 13-price pneumonia vaccine.
Children with chronic diseases can receive another shot of 23-price vaccine after receiving the 13-price pneumonia vaccine. There needs to be an interval of at least 8 weeks between the 23-price vaccine and the last shot of 13-price vaccine.
4. Elderly people over 65 years old or children over 2 years old with chronic diseases who are at high risk of pneumonia need to receive the 23-valent pneumonia vaccine every 5 years. What kind of children do the children with chronic diseases here refer to? Including functional or structural
Children with asplenia, HIV infection, leukemia, lymphoma, Hodgkin's disease, multiple myeloma, malignant metastasis, chronic renal failure, nephrotic syndrome, or other conditions with immunosuppression, such as organ or bone marrow transplantation
, as well as children who are receiving immunosuppressive chemotherapy and children who require long-term oral or injected hormones.
5. Should the elderly be given priority to receive the domestic 13-price pneumonia vaccine at their own expense? In foreign countries, for the elderly who have not received the pneumonia vaccine in the past, the standard recommendation is to receive one shot of the 13-price pneumonia vaccine first, and then take the 23-price vaccine after an interval of at least 1 year.
Pneumonia vaccine.
However, unfortunately, neither the imported nor the domestically produced 13-valent pneumonia vaccine currently on the market has been approved for use in the elderly.
Therefore, the elderly can only directly pay the 23 price in China.
6. If the baby has been infected with pneumococcal bacteria, does he still need to be vaccinated against pneumonia? If the baby is over 6 years old and in good health, no further vaccination is required.
For babies under 6 years old, vaccination is recommended.
Because there are more than 90 serotypes of pneumococci, we don’t know which serotype the baby was previously infected with.
Even if it is known, the child is not immune to other serotypes, so vaccination is still recommended.
7. I have already received the imported 13-price vaccine. Can the unfinished injections be converted to the domestic 13-price vaccine? I have already received the imported 13-price pneumonia vaccine. It is recommended that I continue to choose the imported vaccine to complete the remaining doses.
If imported vaccines cannot be chosen due to shortages, overage, etc., domestic vaccines can be used instead.
