Complementary and alternative medicine has a long tradition of opposition against immunisation. The aim of this article is to determine whether chiropractors, homeopaths and naturopaths advise parents through websites not to immunise their children against measles. A search of the Internet was conducted employing the search engine Google. The contents of the first 12 websites for each of the three categories (i.e. chiropractic, homeopathy and naturopathy) were printed and analysed according to predefined criteria. Of the 36 websites identified, only two offered advice in favour of conventional immunisation; three sites presented information that was considered neutral. The remaining sites did not recommend immunisation and most promoted anti-immunisation attitudes. It appears that the anti-immunisation stance of these healthcare professionals does not seem to be abating. As this position is likely to affect immunisation-rates, it is recommended that effective ways of dealing with this problem be found.
