Continu fever n after vaccine.

My father vaccinated 0n 16th april during Navdurga Fasting and since next day fever is persisting. Paracetamol 500mg, vit-c, Multivitamins are being given to him since that day. On 24th april he felt excessive discomfort - congestion in chest, mild fever, unable to eat food. After compelling he took little amount of fruits and a Chapati. Than we took him to doctor, he didn't see him but gave a telecall prescription. He was advised Azithromycin 500, Vit C, Multivitamins, Montelukast Fexofinadine, Sinocold, Syrup Tusp- Br. Blood Test reports are attached. CRP (Quantitative) is 15.4. Today doctor prescribed one for medicine- Delocin 100. SPO2 level is 93 to 95 since 4 days. Before that we had never checked. Please suggest should I continue with same treatment.
