Key result
A two-dose schedule of the Hecolin vaccine can effectively replace the standard three-dose schedule during hepatitis E virus outbreaks in resource-limited settings.
Why the study?
Does a 2-dose schedule of the hepatitis E vaccine (Hecolin) provide effective protection during outbreaks in resource-limited settings compared to a 3-dose schedule?
Does a 2-dose schedule of the hepatitis E vaccine (Hecolin) provide effective protection during outbreaks in resource-limited settings compared to a 3-dose schedule?
A 2-dose schedule of the hepatitis E vaccine is effective for outbreak response in resource-limited settings and may be feasible during pregnancy.
Answers are grounded in this paper and cite their sources.
May guide HEV outbreak strategies and pregnancy vaccination; leaves open need for confirmatory trials before practice change.
• The use of Hecolin vaccine with a 2-dose schedule can replace the 3-dose schedule during campaigns in HEV outbreak settings. • Vaccination against hepatitis E during pregnancy may be feasible. • A single dose of the vaccine may not provide full protection.
