Poster, 'Your child can be protected against: diptheria, whooping cough, tetanus, polio, small pox'. Immunisation for diphtheria, whooping cough and tetanus, one of 800 health education posters produced for the Central Council for Health Education (1927-69), Health Education Council (1969-87) and Health Education Authority (1987-2000).

A combined vaccine for diphtheria, whooping cough and tetanus was introduced in the United States in 1946. It was tested in the UK in the early 1950s and subsequently made widely available. From the 1970s there were anxieties that small numbers of children had brain damage as a result, and that parents were not warned. Such anxieties led to a decline in take-up during the 1970s and subsequent epidemics of whooping cough in particular.
