Hi, I'm not sure if this is the right place and apologies in advance if I posted this in wrong forum. I am from ME and wish to join a master immunology program in USA. I have MD degree and currently work in a primary health care center. I tried to apply for immunology programs but they requested a lab experience which is not feasible to me . Is there a program which is good but dose not require either GRE nor lab background?
