Covid vaccination. I go for vaccination?

I am taking allergy tablets for the past one month. i had wheezing and some breathing issues. my dr said this is due to allergy and gastric problems i have. i have burpings also. because my PFT report taken 6 months back is perfectly normal and dont have any asthma or other issues. other than sore throat and little breathing issues i dont have fever or tiredness or loss of taste or smell or any pain in throat. My SpO2 is always above 96 and mostly 97 98. My slot is booked tommorrow morning. i intermittently have sore throat and mucus and it gets fine within 2 days. my dr said do a CRP test if the results are normal go for vaccination. nothing to worry. i dont have any drug allergies. But i have a dilemma and fear for vaccination. Can i go for vaccination? Kindly help me out.
