§ 24. Mr. YEOasked the Under-Secretary of State for War whether some of the British soldiers in Europe who were inoculated against typhoid fever a few months ago are being re-inoculated; whether these men are being told that in order to be properly protected against typhoid they must be inoculated every six months; and whether periodical re-inoculation for the troops is being generally recommended?
§ Mr. TENNANTThe answer to the first two parts of the question is in the negative. Re-inoculation is recommended after two years for men protected by two doses, and after six months for men who have been only partially protected by single doses of vaccine.
