title: Rubella immunity.
abstract: Rubella immunisation must continue, with special attention given to women from ethnic minorities, nulliparous women and women over 25 years old, research from London concludes. A study of 14,752 women attending antenatal classes in three London hospitals between 1981 and 1984 showed that the overall proportion of seronegative women fell from 9.6 per cent to 4.3 per cent.
