Suitable covid vaccination for my wife.

My wife is having allergy from dust and smoke. Occassionally she experienced difficulty in breathing and excess of cough mucus when she came in contact of dust or smoke. When this happens she takes 1 tab L montus AB, 1/2 doxomax XP 400mg - 2 times a day and Grilinctus BM 5 ml - 3 times a day. Doctor also recommended nebulizer, in case of severe problem. During her pregnancy, Doctor asked her to use Levolin inhaler which helped her during minor problem. My question is, is it safe for her to take Covid vaccination? I have seen in my videos where doctors are advicing to take extra precaution for people allergic to anything. We are planning to get vaccinated but due to this we are very scared of any side effects. Please let us know what precautions we need to take, anything we need to keep in mind or need to do before vaccination and which vaccination is suitable for my wife. Thanks for your help in advance.
