Covid Vaccine side effects concern.

I often sneeze sometimes probably because of dust allergy,etc and it becomes normal after some time. This happens once a day on an avareage. I had taken homeopathic medicine for this which is helpful. Also, I do have allergic reaction to prawns- After eating, I start sneezing, watery eyes, and little uncomfortable to breathe which gets normal after sometime as well. Sometimes take general allergic medicine for faster effect. This happened thrice and now I avoid having prawns. No apparent issue with any other food item. My question is- I am 30 years old. Am I fit to take Covoshield or covaxin vaccine against Covid-19 since 18+ age can take from May 2021. I am concerned that there would be no severe side effects due to my normal allergy issue as described above. Please suggest.
