Effectiveness of Lanzhou lamb rotavirus vaccine against rotavirus gastroenteritis requiring hospitalization: a matched case-control study.
We sought to determine the vaccine effectiveness (VE) of Lanzhou lamb rotavirus (LLR) vaccine against rotavirus gastroenteritis in children <5 requiring hospitalization. Children hospitalized 2002-2004 with rotavirus gastroenteritis were matched by gender, age and community to 838 controls. VE was calculated for one or more doses of LLR vaccine with 95% confidence intervals (CI). For one dose versus zero doses, LLR vaccine VE was 73.3% (95% CI, range 61.2-81.6%). VE of one dose versus zero doses was higher in children 12-23 months than in children 2-11 months (80.9% versus 60.0%). We found one dose moderately effective in preventing rotavirus gastroenteritis requiring hospitalization.
