A brief explanation:

Sub Molecular Medical Sciences (SMMS) is about taking a complicated quantum mechanics idea and DEMONSTRATING HOW it manifests itself in life, for instance in medical treatments and diagnostics.

Quantum biology (QB): Quantum mechanics (QM) physics APPLIED TO biological processes is Quantum biology.

INTERDISCIPLINARY: the domains of mathematics, physics, computer science, biochemistry, biology, medicine, and legislation are all included in the whole spectrum of SMMS by means of government reviews and role in the subject.

Hence the SMMS domain require expertise in different areas.
