We have investigated the attitudes towards vaccination of undergraduate chiropractic and naturopathic students in the two major complementary and alternative medicine colleges in Canada. While the majority of the students were not averse to vaccination, we found in both colleges that anti-vaccination attitudes were more prevalent in the later years of the programs. Reasons for this are discussed, and we provide suggestions for strategies to address the situation.
