Hello doc I have had eczema..very infrequent. I had in my school time or teens(more then) and after that only this year(less comparatively)...for which I apply ointment when it occurs.. Apart from this, allergic to penicillin. My question is which vaccine is appropriate for me... Covaxin or covishield? As they say to decide based on your allergic reactions and preexisting conditions. Pls advise urgently.
