Abortions and premature deliveries after RB51 mass vaccination in brucellosis free herds in several Spanish regions. Left panels: abortions and premature deliveries in ten brucellosis free herds before (in white [year 2009]) and after (in black [year 2010]) subcutaneous vaccination and revaccination after six months with full doses of RB51 irrespective of the age and reproductive condition. RB51 was isolated from the abortions, vaginal swabs and milk of affected cows in herds 1, 4, 5, 7, 8 and 9 (herds 2, 3, 6 and 10 were not tested bacteriologically) (adapted from [101]). Right panel: abortions (a), weak newborns (b) and dead-born calves (c) commonly observed in brucellosis free herds submitted to whole vaccination (years 2009 and 2010). RB51 was isolated from the aborted material, vaginal swabs and/or milk samples (pictures kindly provided by O. García)
