在英国,一项新的研究显示:近来麻疹发病率的增加很可能是由于部分人群拒绝接种MMR疫苗(麻疹、腮腺炎、风疹联合疫苗)引起。专家们担心如果当前的疫苗接种率再不提高,麻疹可能会在英国再度大规模流行。 麻疹是高传染性的病毒性疾病,一直是可接种预防疾病中导致儿童死亡的首要因素。 In the UK, a new study shows that the recent increase in the incidence of measles is most likely caused by the refusal of some populations to immunize MMR vaccines (measles, mumps, and rubella). Experts fear that measles may be pandemic again in the UK if the current vaccination rate does not rise any further. Measles is a highly contagious viral disease and has been the prime factor in vaccination to prevent child mortality in the disease.
