Facilitators, barriers, and considerations in implementing vaccine programs & campaigns.

Type	Themes	Description
Facilitator	•Economic support	•Free vaccines [10,11] •Vaccines & syringes donated by manufacturers [12] •Funded, by non-profit public-private partnership [13,14]
	•Effective management of vaccination programs	•Signups for vaccine to estimate demand [14] •Reallocated unused vaccines to nearby sites [14] •Close timing of sign up to vaccination session date [14] •Support & encouragement from institution leaders [14] •Use of existing EPIa infrastructure [14,15]
Barrier	•Lack of awareness & inefficient communication	•Lack of awareness of availability [16] •Lack of education [[16], [17], [18]] •Larger facilities had lower signups due to less face-to-face promotion [14]
	•Lack of funds	•Lack of long-term funding [19] •High costs [[20], [21], [22], [23]]
	•Difficult access & lack of vaccines	•Lack of time and/or opportunity [16,18] •Unavailability of vaccine doses [17,19,24] •Lack of accurate baseline data on antigen prevalence rates [25]
	•Lack of data
Consideration	•Increasing cost-effectiveness	•Consider cost-effectiveness of screening for HBV antibodies prior to vaccinating those susceptible vs. universal vaccination [26,27] •EPI (introduced 2005) does not cover older HW (program gap) [28,29]
