Thank you for your query on Healthcare Magic.
Usually after chickenpox vaccination
, there will no fever but mild fever can be expected after any injectable vaccination.
But getting temperature of 103 degree F is uncommon with chickenpox vaccine.
It may be due to a viral infection not related to the vaccination.
in prescribed dosage and do tepid sponging with lukewarm water.
If the fever is not coming down within 24 to 48 hours consult your Pediatrician
for the examination to look for the focus of infection and for treatment.
Hope I have answered your query.
