自1982年始至今,我们为了验证疫苗效价,加强卡介苗接种的免疫效果,用随机抽样原则,对86年元月初次皮内接种卡介苗的一岁组儿童进厅接种后十二周阴转率调查,并进行有无卡痕的观察登记。用1ml兰芯注射器、4(1/2)号针头,卫生部药品生物制品检定所提供的86—2号纯结核菌素(PPD—C).失效87年2月。将PPD—C液0.1ml缓注于左前臂掌侧中部1/3之处的皮内,局部见6×7mm小皮包,结素接种后72小时观察局部反应:阳性是硬结纵横平均直径>5mm,阴性1—4mm无硬结者,强阳性15mm以上者。本此共调查266名,有卡痕(包活5mm以下者)259人,卡痕率97.37％。县站和乡村有痕(不包括
Since 1982, in order to verify the potency of vaccines and to enhance the immune effect of BCG vaccination, we investigated the negative conversion rate of twelve weeks after the first intradermal BCG vaccination in January 1986 , And the presence of card marks observed registration. Sterile tuberculin (PPD-C) No. 86-2 provided by the Ministry of Health, National Institute of Biopharmaceutical Products, Ministry of Health, was used with 1ml Lancet syringes and 4 (1/2) needles. 0.1 ml of PPD-C solution was slowly injected into the skin of the middle 1/3 of the left forearm’s palmar, and a small 6 × 7 mm purse was seen locally. The local reaction was observed 72 hours after inoculation. The positive rate was> 5mm , Negative 1-4mm no induration, strong positive 15mm or more. A total of 266 this survey, a card marks (including living 5mm below) 259 people, card rate of 97.37%. County stations and rural marks (not included
