Talk to General Physician on Covid Vaccincation Query

AoA. I along with my wife and father got infected with covid in January 2021. After recovering (alhamduillah) we got IgG tests done for antibodies from Chughtai in February. My father's value was 400, wife's value was 350 and my value was 21. Reference value was 15.

I have two questions. First, should we get vaccinated right away or should we wait and give the chance to other people for now? Secondly, if we get vaccinated, should we get two doses or just one?
