Abstract
The paper of Baxter et al., recently published in Pediatrics show through five cross-sectional studies, a high impact of vaccination in the decline of varicella incidence and hospitalizations in all age groups in the United States between 1995 and 2009. As a consequence of herd immunity, varicella incidence has also diminished in those non vaccinated, which indicates no shift in the burden of varicella to older age groups.Keywords: Varicella; chickenpox; epidemiology; vaccine impact; varicella vaccination
