asked the Minister of Health, whether he is aware that two cases of small-pox were recently removed from a street in Doncaster, three weeks after vaccination had been performed in each case; and whether any other smallpox cases at Doncaster, or elsewhere, during the past two months have developed after recent vaccination?

The answer is in the negative. I am informed by the medical officer of health that in no case has small-pox occurred in Doncaster after recent vaccination where the interval between vaccination and the development of the disease has exceeded 14 days; and I am not aware of the occurrence of any such case elsewhere during the past two months.
