Group	Dogs with two or more cumulative days of cough	Number of dogs with disease (consecutive days of cough)*	Per cent of dogs with disease	Prevented fraction (95%  CI)
Recombitek® Oral Bordetella (n=10)	2	0	0.00	1.00 (0.67 to 1.00)
Placebo vaccine (n=9)	8	8	88.9
Nobivac® Intra-Trac3 (n=10)	1	0	0.00	1.00 (0.67 to 1.00)

*Significant difference between groups (Fisher’s exact test P<0.0001).
