Preliminary research shows that supplemental vitamin A improves the likelihood that the measles vaccine will provide protection. 6 Vitamin A has, since the 1920s, been the subject of much research into the prevention and treatment of childhood exanthems, particularly measles. 7 This nutrient has a critical role in proper immune function , and there is evidence that supplementation with vitamin A reduces the incidence and severity of, and deaths from, childhood measles. 8 9 The World Health Organization has therefore recommended that children with signs of deficiency receive supplementation with vitamin A. The recommended amounts are 100,000 IU for children younger than one year and 200,000 IU for children older than one year, immediately upon diagnosis, and repeated once the next day and once in one to four weeks.

11初步研究表明，补充维生素A的可能性，提高麻疹疫苗将提供保护。6维生素A已自20世纪20年代，被纳入预防和童年exanthems，特别是麻疹治疗中的许多研究课题。7本养分有在适当的关键作用免疫功能，并有证据表明，补充维生素A减少发病率和严重程度，以及，儿童麻疹死亡。8 9世界卫生组织已因此，建议与不足的迹象儿童得到补充与维生素A的建议金额10万国际单位的儿童未满一年，20万国际单位的儿童一年以上，立即诊断，重复一遍，第二天，一次在1至4周。
