In the US, the Centers for Disease Control and Preventions Advisory Committee on Immunization Practices recommends pre-exposure vaccination for adults 18 years of age who are at highest risk for potential occupational exposure to Ebola virus because they are responding to an outbreak, work as healthcare personnel at a federally designated Ebola treatment center in the US, or work as laboratorians or other staff members at biosafety level 4 facilities in the US. There are no data on the use of Ad26.ZEBOV/MVA-BN-Filo vaccine in pregnancy; however, vaccination should not be withheld when there is a clear risk of exposure.

Vaccinations, counseling to change high-risk behaviors, and sometimes chemoprevention are types of primary prevention. Prevention, as it relates to health, is really about avoiding disease before it starts. The severity of the illness, injury, or environmental hazard; The nature of the suspected etiologic agent; The number of possible susceptible persons and the extent of their exposure; and. 2018 Apr;18(4):378.
