WASHINGTON — President Donald Trump said Monday that medical and pharmaceutical groups could be the reason that the establishment media refuses to ask questions about vaccines. Shortly after the president signed an executive order revising childhood vaccine recommendations, Breitbart News asked the president why the establishment media so often refuses to even ask questions about vaccines. Trump said that he believes the revised childhood vaccine schedule will yield “tremendous results.” “States that enact school vaccine requirements are advised to consider the Gold Standard Childhood Vaccine Recommendations and consider updating their laws to reflect the recommendations,” the White House noted in a release. “All Federal agencies are advised to advance the Gold Standard Childhood Vaccine Recommendations based on their relevant authorities to ensure Americans have the best scientific information,” the release added.
