Covaxin vaccination and allergies.

My mother is having issues with the dust and food ( lemon, chicken, green chilies, tamarind) allergy. No phlegm is seen. Only watery mucus when she sneezes. They make her sneeze and congested nose. Her nose is blocked all the time and sneezes more than 20times a day. She is not on any medication for the nasal issues. She has this allergy past 18 years. She is on below medication for blood thinners, BP diabetes and and psychiatric meds Concor 5mg (2.5 mg in the morning and 2.5mg at night) Istamet 50/500 ( morning dose) Atorfit CV 20mg - (night dose) Psychiatric medication - Clopixol Depot 200mg Can she still take COVAXIN Vaccination? Should she stop blood thinners a day before the vaccine and after ? Will her existing allergies cause any issue ? She took Clopixol Depot 5 days ago . Vaccine slot is day aftr tomorrow. Please help
