abstract: Using Google, sites expressing position against, or critical towards, vaccinations have been searched among the first 200 pages obtained using both "vaccine" and "vaccination" as key words. Position against compulsory vaccination or doubt about vaccine safety were found in 47 pages. The repetition of false news induces to think they are true and difficult to refute, while vaccine preventable diseases continue to cause damages.
