Em 1967, os médicos introduziram um método de injeção sem agulha conhecido como injetor a jato. Em vez de perfurar a pele com uma agulha, ele utilizava um jato de líquido de alta pressão, forte o suficiente para administrar vacinas e medicamentos diretamente através da pele. Essa inovação provou ser especialmente útil durante campanhas de vacinação em massa, como as de varíola, porque permitiu que os profissionais de saúde tratassem um grande número de pessoas rapidamente.
