Several studies have been conducted evaluating ID delivery of measles vaccine, with mixed results (Burland 1969; Kok et al. 1983; Whittle et al. 1984; de Moraes et al. 1994) . However, the vaccine dose and method used to deliver the vaccine varied, and it is possible that trials using older generation delivery technology did not deliver vaccine reliably to the dermis (PATH 2009). Transcutaneous immunization of measles vaccine on a coated patch has also been attempted. Although a salivary sIgA response was observed, the key marker of immunity, an increase in neutralizing serum IgG, was not detected (Etchart et al. 2007 ).
