Abstract
Along with the improvement of diagnostic techniques, hepatitis E has attracted increasing
awareness in recent years. Hepatitis E virus infection leads to high mortality in
pregnant women and patients with underlying liver disease. Several hepatitis E vaccine
candidates have been designed and have proved their efficacy in animal models; two
candidates have successfully undergone clinical trials. Having proved safe and effective
in a large phase III trials, an Escherichia coli expressed particulate protein, HEV 239, has been registered in China and is now available
for use in China.
