If the fever after varicella vaccination is only asymptomatic and low, it can subside by itself without special treatment. If the fever is persistently high, it is necessary to consult a doctor in time for appropriate fever-reducing and anti-infection treatment.
1. Asymptomatic low-grade fever: After varicella vaccination, some people may have transient low-grade fever, which belongs to the general adverse reaction of vaccination, and can subside by itself, so just pay attention to observation. You can drink more water, eat a light diet, or use warm water bath, antipyretic patches and other ways to reduce fever.
2. Persistent high fever: If the fever after vaccination is persistently high, or accompanied by nausea, vomiting, diarrhea and other discomforts, it is considered to be caused by secondary infection. It is necessary to consult a doctor in time and follow the medical advice to reduce fever (e.g., ibuprofen) and anti-infection (e.g., cefixime) treatment. The use of drugs should be under the guidance of a medical professional.
To summarize, a transient low-grade fever after vaccination is a normal reaction to vaccination, and can be physically cooled down on its own by paying attention to monitoring the body temperature, but if it is a persistent high fever, it is necessary to consult a doctor and follow the doctor’s instructions for treatment.
