§ Mr. GROVES
asked the Minister of Health whether any of the Blackburn small-pox patients had been vaccinated before removal to hospital with smallpox; and, if so, how many days before such removal was the vaccination per formed in each case?
Sir H. YOUNG
Five patients were vaccinated shortly before removal to hospital. Two of these were vaccinated during the incubation period of the disease, six and 10 days respectively before removal. Three were vaccinated after the illness had begun, one on the day of removal, one the day before removal and the third four days before removal.
