Pneumonia is a common infectious disease of the respiratory system. For the elderly who are frail, infants and young children who repeatedly suffer from pulmonary infections, and adults with immune deficiencies, it is an option to get vaccinated against pneumonia. Generally, antibodies are produced in the body 2 to 3 weeks after vaccination, which may protect against most types of pneumococcal bacteria. Different pneumonia vaccines vary in the duration the antibodies last in the body, with most lasting about one year. For bivalent and trivalent pneumonia vaccines, the immune protection can last about five years.

How many doses are there for the pneumonia vaccine?

Currently, there are two types of vaccines commonly used to prevent pneumococcal diseases. One type is the 23-valent polysaccharide vaccine, suitable for high-risk populations over two years old. The other type includes the 7-valent or 13-valent conjugate vaccines, used for vaccinating infants under two years old. The vaccination schedule for the 7-valent or 13-valent vaccines follows a "three plus one" program, which means three primary immunization doses with at least one month between each dose, followed by a booster dose. For the 23-valent vaccine, high-risk individuals over two years old generally require only a single dose; however, immunocompromised patients may need a booster shot, typically recommended five years after the initial vaccination.

How is pneumonia treated?

Pneumonia is a common disease in clinical practice, with patients often experiencing symptoms such as fever, cough, and expectoration. If a lung X-ray is taken, shadows can be seen in the lungs. The treatment of pneumonia primarily involves addressing the cause. For instance, if it is bacterial, appropriate sensitive antibiotics are chosen for treatment. If it is caused by a virus, suitable antiviral drugs are selected, and for fungal pneumonia, antifungal drugs should be chosen. If it is related to allergies, anti-allergy medications should be used. Additionally, symptomatic treatment is applied, such as antipyretics for fever. Depending on the situation, medications for cough suppression, phlegm reduction, and asthma relief may also be used. (The use of medications should be under the guidance of a doctor.)

Additionally, adults over two years old or other high-risk groups are advised to take the 23-valent vaccine, which requires only a single dose. However, those who are frail or have poor immune responses may need a second booster dose five years after the initial vaccination.

symptoms of pneumonia in children

Pneumonia is a particularly common infectious disease of the respiratory system. Children, due to decreased disease resistance and low immunity, are especially susceptible to upper respiratory and lung infections. The main clinical symptoms of childhood pneumonia are fever and cough. Additionally, children may experience loss of appetite and vomiting. When these symptoms occur, it is advisable to take the child to the hospital for an examination. The doctor can perform auscultation and collect routine blood tests to preliminarily determine the presence of an infection. If pneumonia is suspected, further imaging studies are recommended for a definitive diagnosis.

Can pneumonia be cured?

Can pneumonia be cured, and will there be any sequelae? Generally speaking, common pneumonia without complications can be completely cured. If pneumonia infection is detected, seek medical attention in a timely manner and treat it rationally under the guidance of a professional doctor, it generally will not leave sequelae or affect lung function. However, some complications of pneumonia, such as meningitis and pericarditis, may leave symptoms like headaches, dizziness, palpitations, and chest pain. Ordinary pneumonia might leave streaky shadows or irregular pleura on chest X-rays or lung CT scans, but these will not impact the human body. Patients who have previously been infected with tuberculosis may have calcification spots in their lungs, which is a normal phenomenon. Some people may experience sequelae after treatment, such as hearing loss caused by the use of antimicrobial drugs, and avascular necrosis of the femoral head occurring after SARS treatment; however, these are possibly side effects of the drugs, rather than sequelae of pneumonia.
