混合血浆,恢复期血清,丙种球蛋白均已成功地用于麻疹易感接触者的预防,但仅赋予数周保护作用。因此,大多数使用的目的,都是试图改变丙种球蛋白注射量和注射时间以减轻病症,并获得随后的持久免疫,可惜这种想法难以实现。普遍认为接触后及早注射疫苗,可以在潜伏期内获得保护,但不并用丙种球蛋白,单独接种疫苗有效的证据似嫌不足。Watson报导一个小家庭于爆发后第三天接种疫苗成功。美国公共卫生免疫实施咨询委员会宣称在接触后两天内接种疫苗一般能获得保护。短暂的类麻疹症状(发热、咳嗽、皮疹)是疫苗常见反应,使得评价疫苗对接触者的 Mixed plasma, convalescent serum, gamma globulin have been successfully used in the prevention of measles-susceptible contacts but only given weeks of protection. Therefore, the majority of the uses are intended to alter the gammal injection volume and timing of injection to alleviate the condition and to obtain a subsequent long-lasting immunization, unfortunately this idea is difficult to achieve. It is generally accepted that early vaccination after exposure can be protected during the incubation period, but immunoglobulin is not used together with evidence of effective vaccination alone. Watson reports the success of a small family vaccination on the third day after the outbreak. The US Public Health Advisory Committee on Immunization claims that vaccination is generally protected within two days of exposure. Brief measles symptoms (fever, cough, skin rashes) are a common response to vaccines, making the assessment of the vaccine’s response to contact
