Introduction

Fever generally refers to an elevated body temperature. Fever after receiving the final dose of the 13-valent pneumococcal vaccine may be due to adverse reactions from the vaccine or caused by a viral infection. During the process in which the vaccine stimulates the body to produce antibodies, fever may occur as a normal vaccine reaction. Typically, the fever is mild and lasts for about 1 to 3 days before resolving on its own.

Fever generally refers to an elevated body temperature. After receiving the final dose of the 13-valent pneumococcal vaccine, fever may occur as a result of adverse reactions to the vaccine or due to a viral infection.

1. During the process in which the vaccine stimulates antibody production in the body, symptoms such as fever may appear. This is usually considered a normal vaccine reaction. The fever is typically mild and often resolves spontaneously within 1 to 3 days.

2. Fever following the final vaccine dose could also be caused by secondary viral infection. Vaccination might temporarily lower resistance, increasing susceptibility to viral infections. In such cases, it's important to visit a hospital to determine the underlying cause and receive appropriate symptomatic treatment.

Treatment options for fever after vaccination include:

1. If the fever resulting from a vaccine reaction is below 37.5°C, physical cooling methods can be used, such as fever-reducing patches, suppositories, applying a warm towel to the forehead, or wiping areas rich in large blood vessels (such as the groin and armpits) with alcohol to help reduce body temperature.

2. If the fever is caused by a viral infection, further examinations are needed to confirm the diagnosis. Besides reducing fever, treatment should also target the underlying illness. For fevers caused by bacterial infections, antibiotics such as levofloxacin, roxithromycin, or cephalosporins may be prescribed under a doctor’s guidance.

After vaccination, observation and conservative management are recommended for fever. It's advisable to drink plenty of warm water to promote the elimination of metabolic waste products. Avoid taking antiviral or anti-inflammatory medications unless necessary.

Does the 13-valent pneumococcal vaccine cause fever with every dose?

Fever generally refers to an elevated body temperature. Not everyone will experience fever after receiving each dose of the 13-valent pneumococcal vaccine; however, some individuals may develop a fever, which is considered a common adverse reaction. If the fever is low-grade, no special treatment is required. It is recommended to drink more hot water at home, and symptoms usually resolve spontaneously after 2–3 days of rest. If a high fever develops, exceeding 38.5°C, antipyretic treatment should be administered.

What causes fever after receiving the fourth dose of the 13-valent pneumococcal vaccine?

Fever generally refers to an elevated body temperature. Fever after receiving the fourth dose of the 13-valent pneumococcal vaccine may be due to an adverse reaction to the vaccine or a viral infection such as the common cold. Therefore, symptoms such as fever, rash, diarrhea, and increased sleep may occur after administration of the 13-valent vaccine. If symptoms are not severe, it is recommended to drink plenty of fluids, get adequate rest, and avoid fatigue and staying up late. Adverse reactions usually resolve on their own.

What is the difference between the 13-valent pneumococcal vaccine and the 23-valent pneumococcal vaccine?

The differences between the 13-valent pneumococcal vaccine and the 23-valent pneumococcal vaccine include variations in vaccination coverage, technology, target populations, and more. The 13-valent pneumococcal vaccine protects against 13 types of Streptococcus pneumoniae, while the 23-valent pneumococcal vaccine protects against 23 types, offering broader coverage than the 13-valent vaccine. In addition to these differences, the two vaccines also differ in their compositional components.

Can the 13-valent pneumococcal vaccine and the AC meningococcal vaccine be administered together?

The 13-valent pneumococcal vaccine and the AC meningococcal vaccine can be administered simultaneously, but this should be done under the guidance of a doctor. Both the 13-valent pneumococcal vaccine and the AC meningococcal vaccine are designed to prevent bacterial infections, effectively protecting against diseases such as pneumonia and meningococcal meningitis. Administering these two vaccines together can enhance immunity and reduce the risk of infection.
