Fecal specimens from children presenting to Texas Children's Hospital with acute gastroenteritis were tested for the presence of rotavirus. Children were grouped according to vaccination status, and pentavalent rotavirus vaccine effectiveness was calculated. Pentavalent rotavirus vaccine effectiveness against severe rotavirus gastroenteritis was sustained during the first 2 years of the vaccination program. Overall 3-dose effectiveness was 83% to 86%; it was 92% to 93% among children 6 to 11 months of age and 78% to 84% among children ≥12 months of age.
