How long after receiving the 13-valent vaccine will fever occur?
Fever generally refers to an elevated body temperature. The "13-valent vaccine" refers to the 13-valent pneumococcal polysaccharide conjugate vaccine. It is inaccurate to ask how long fever typically lasts, as not everyone will develop a fever after vaccination. Specific details are as follows:
The 13-valent pneumococcal polysaccharide conjugate vaccine is used for active immunization in infants and young children and helps prevent invasive diseases caused by Streptococcus pneumoniae. After administration, the body produces specific antibodies. However, because individuals have different physical constitutions, reactions following vaccination may vary. Not all vaccinated individuals will experience fever. If fever does occur, it usually develops within 48 hours after vaccination and generally does not last longer than 48 hours.
If symptoms such as joint pain, loss of appetite, fever, chills, or other severe reactions occur after vaccination, or if the fever persists or repeatedly spikes, prompt medical attention at a hospital is recommended.
