However, the incubation period for Omicron and its offshoots is believed to be much shorter between three and five days. In the omicron era, one might want to think about requiring a booster to be considered fully vaccinated, says Sten Vermund, MD, PhD, an infectious disease epidemiologist, dean, and professor at the Yale School of Public Health and Yale School of Medicine in New Haven, Connecticut.
