A breast cancer vaccine could be closer to reality, according to Cleveland Clinic, as its researchers have announced some encouraging results. Researchers and doctors weigh in.

The vaccine appears to be safe and effective against triple-negative breast cancer -- a type that can’t be treated with hormone therapy because it isn’t driven by any of the three hormones that typically fuel breast cancer.

A new vaccine is offering hope for people fighting an aggressive form of breast cancer. Dr. Michael Daignault talks about this vaccine as well as other medical news.
