Mrs. Butlerasked the Minister of Health what were the numbers of diphtheria cases and deaths recorded in immunised and unimmunised persons, respectively, in the different age groups in the years 1955, 1956, 1957, 1958, 1959, and 1960; and what was the percentage in each age group which had been immunised at the time.
§ Miss PittI regret that this information is not available by age groups. The totals were as follows:
67W
Mrs. Butlerasked the Minister of Health what evidence he has that inoculation for diphtheria is avoided at a time when poliomyelitis is prevalent; and what is the reason for this.
§ Miss PittWhen poliomyelitis is prevalent in a locality it is the normal practice to suspend routine immunisation against other diseases, including diphtheria, in order to avoid any risk of provoking paralysis in a person already infected with poliomyelitis virus.
