“Credible scientific and medical information about vaccines can be gotten from reading the websites of medical organizations and government public health websites, science and medicine textbooks by mainstream publishers and reading scientific review papers in highly credible scientific journals.

Although certainly not infallible, together they represent the best information currently available.
Anti-vaccine activists, on the other hand, primarily rely on misleading information found on conspiracy blogs, YouTube videos and Facebook groups. These are not credible sources.
