What are the side effects of the 23-valent pneumonia vaccine?

　　The term "23-valent pneumonia" refers to the 23-valent pneumococcal vaccine. Under normal circumstances, the 23-valent pneumococcal vaccine may cause some adverse effects, such as discomfort at the injection site, mild systemic discomfort, allergic reactions, gastrointestinal disturbances, and fever. These effects can usually be alleviated through localized heat application, massage, medication, and other methods. If other uncomfortable symptoms appear, it is recommended to seek medical attention promptly at a reputable hospital. The specific analysis is as follows:

1. Discomfort at the Injection Site

　　After receiving the 23-valent pneumococcal vaccine, redness, pain, or hard lumps may appear at the injection site. This discomfort is typically temporary and can be relieved by applying local heat compresses and gentle massage.

2. Mild Systemic Discomfort

　　Some individuals may experience mild systemic discomfort after vaccination, such as headache, fatigue, and muscle pain. These symptoms are usually transient and resolve on their own. It is recommended to rest adequately, avoid strenuous exercise, and stay warm to prevent worsening symptoms due to cold exposure.

3. Allergic Reaction

　　Some people may experience an allergic reaction to components of the vaccine, presenting symptoms such as rash, hives, and difficulty breathing. If a severe allergic reaction occurs, immediate medical attention should be sought. Medications such as hydrocortisone butyrate cream, mometasone furoate cream, and loratadine tablets may be used under medical guidance to alleviate symptoms.

4. Gastrointestinal Discomfort

　　A small number of individuals may experience gastrointestinal discomfort after receiving the 23-valent pneumococcal vaccine, such as nausea, vomiting, or diarrhea. Symptoms can usually be relieved by resting appropriately and maintaining adequate hydration.

5. Fever

　　After vaccination, some individuals may develop a fever with elevated body temperature. In most cases, this fever is mild and resolves on its own. However, if the fever persists for a long time or the temperature is excessively high, antipyretic medications such as ibuprofen sustained-release capsules, acetaminophen tablets, or cefixime tablets may be taken under medical guidance.

　　It is recommended to receive the vaccine under a doctor's guidance and closely monitor your physical condition after vaccination. If adverse reactions occur, seek medical attention promptly. Proper care of the injection site should be ensured, and contact with water should be avoided too soon to prevent compromising the effectiveness.
