Vaccine type |
Replication-competent viral vectors |
Appropriate for healthy adults and children, non-pregnant women |
|
Non-replicating vectors and protein subunit vaccines |
Appropriate for the general population including immunocompromised and pregnant women |
Species coverage |
Monovalent protection against Zaire ebolavirus
|
Useful only for outbreak response to a known Zaire ebolavirus outbreak |
|
Broad protection against Zaire ebolavirus, Sudan ebolavirus, and Bundibugyo ebolavirus
|
Useful in multiple outbreak settings and for preemptive vaccination of international aid workers and healthcare/frontline workers in regions with multiple endemic species |
Dosing regimen |
Single dose |
Ideal regimen for outbreak response |
|
Primary dose plus booster dose(s) |
Difficult to implement as part of outbreak response where vaccinees may not be accessible or compliant for follow-up dose(s) Feasible for preemptive vaccination of
