as per your daughter lab report first there is no any association in between vaccination
and presence of epithelial cell in urine .
9 week old child means receive DPT , HEP B , HIB , OPV. among these DPT vaccine
causes fever , but usually fever get subside with paracetamol
only in 2-3 days .
no need to worry at all .
if fever is high grade and lasting long than cause might be other , than u need all blood test
. and few epithelial cells
in urine and if no pus cell no other abnormality means this is normal one . occasionally few epithelial cell can comes .
if fever persist consult to your doctor
