Rubella haemagglutination antibodies were tested for in sera of 1793 unvaccinated subjects with age ranging from birth to 40 years. This was to assess the immune status of the population and to see the feasibility of introduction and the proper age for rubella vaccination in a Saudi community. Those with titres of greater than or equal to 1:8 were considered as seropositive. The lowest level of antibodies was seen among the 10-18 month age group. All children aged 2-5 years were seropositive as were 75% of the elementary school girls. Only 90-95% of the women of childbearing age were seropositive, however, leaving an immune gap of 5-10%. Unnecessary mass vaccination of young children is discouraged. Rubella vaccine should be given to all final elementary school girls and all women of childbearing age after screening, whenever possible. Special catchment zones are suggested for the latter group. Further nationwide seroepidemiological surveys are recommended for the other parts of the Saudi Kingdom.
对1793名年龄从出生到40岁的未接种疫苗者的血清进行了风疹血凝抗体检测。目的是评估该人群的免疫状况，以及在沙特社区引入风疹疫苗的可行性和合适的接种年龄。抗体效价大于或等于1:8者被视为血清阳性。抗体水平最低的是10至18个月龄组。所有2至5岁的儿童均为血清阳性，小学女生中75%也是如此。然而，育龄妇女中只有90%至95%为血清阳性，留下了5%至10%的免疫空白。不鼓励对幼儿进行不必要的大规模接种。风疹疫苗应尽可能在筛查后接种给所有小学高年级女生和所有育龄妇女。建议为后一组设立特殊的集中接种区。建议对沙特王国其他地区进行进一步的全国血清流行病学调查。
