My daughter is 4 and half month old. On 18th august - 2014, she was given pneumococcal vaccine (PCV-13), however, from 19th august we observed the baby had fever. while consulated with the doctor, he recommended it the viral infection and gave the medicine. however, fever did not last for 7 days and it was recurring at fluctuating between 98.5 to 102 F and sometines read 97.5 F with some coughing. What could be the possible cause of the fever not stopping. In blood test only slightly increased level of monocytes, lymphocytes and phosphocytes were found and no typhoid detected. we are giving the baby Taxim -O, Meftal-P and sinarest. Please advise what to do ?
