Cover Story: In March 2022, a locally acquired human case of Japanese encephalitis (JE) was confirmed in southern Queensland, Australia. Forty cases were subsequently discovered in four states, representing a dramatic range expansion from the virus’ historical presence in far north Australia. Recommendations for JE immunization for the Australian population have now expanded to include those at occupational risk. This includes those working with pigs (a major amplifying host) and those who operate JE surveillance programs. However, many cases during this outbreak appear not to have been infected by these routes, and immunization programs may need to target a much wider population. With a current shortage of JE vaccines in Australia, vaccination with fractional doses may help to stretch the limited supplies. View this paper
