My father and my mother both are 65 years and 58 years respectively. They both were tested covid positive on 1st March'2021 and subsequently they both got recovered as well. My mother is having some allergic issue and both of them had not taken any doses of covid vaccine till date. As we registered their name for vaccination, today they got call for 1st dose of covid vaccination. My query is that should they take vaccine now or not considering the present scenario. Please advice me what should they do now.
