HC Deb 29 October 1918 vol 110 c1295
64. Mr. WRIGHT

asked the President of the Board of Agriculture whether a cow or heifer injected with the Board's anti-abortine vaccine, which is supplied free to farmers who apply for it, remains a carrier of the germ of epizootic abortion, though immune herself, and liable to infect other animals; and, if so, for how long?

The PRESIDENT of the BOARD of AGRICULTURE (Mr. Prothero)

The reply to the first part of the question is in the negative. The second part does not, therefore, arise.
