Analysis of varicella vaccine breakthrough rates: implications for the effectiveness of immunisation programmes

Vaccine, 2000
The objective of this study was to quantify key parameters describing varicella zoster virus (VZV) vaccine efficacy. To do so a mathematical model was developed to represent breakthrough cases as a function of time after vaccination in vaccine efficacy trials.

Breakthrough Varicella Infection in a Healthcare Worker Despite Immunity After Varicella Vaccination

Infection Control & Hospital Epidemiology, 1999
AbstractAlthough varicella vaccination is recommended for varicella-susceptible healthcare workers (HCWs), breakthrough infection after vaccination is not unusual, especially following household exposures. We report breakthrough varicella in a vaccinated HCW and review the data on breakthrough infection and concerns for the healthcare setting.

Physician Attitudes Regarding Breakthrough Varicella Disease and a Potential Second Dose of Varicella Vaccine

Pediatrics, 2007
OBJECTIVE. We assessed physicians’ attitudes about the 1-dose varicella vaccination program and whether physicians think a 2-dose recommendation is needed to reduce the risk of breakthrough disease. METHODS. We conducted a national mail survey of a random sample of 550 pediatricians and 550 family physicians from April to June 2005 ...
