Some users cite that 2 doses of Hepatitis A might not be completed by 19 months of age. This is true. The recommendation schedule sates that 2 doses should be completed by 23 months. In identifying this as a gap, we ask practices to see if opportunities are being missed by delaying receipt of that vaccine to later ages. Are children coming in at 12 and 15 but not 18 months and missing that vaccine?
