I am trying to understand the two-dose Hep B vaccination for children. It appears that in the UK, while not part of standard NHS care, the two-dose schedule is approved for those aged 1 and older (cf. the "green book"). In the US the CDC only approves the two-dose schedule for children 11 and over. What evidence are these decisions based on?
The NHS only advises Hepatitis B vaccination to young children when they are at a high risk of exposure. This means when the mother is infected and contagious, or there are close relatives with the disease. Otherwise vaccination is optional.
The WHO also recommends vaccination from birth so the different stance taken by the NHS may be political or economic..
