UNIONS and campaigners have backed plans for schools to be given access to free teaching materials to help challenge anti-vaccination conspiracy theories. Critical-thinking tools for school assemblies and lessons have been launched by the Stephen Hawking Foundation to help students discuss their concerns and uncertainties. Are Vaccines Safe? provides teachers and school leaders with accurate scientific information on a range of frequently asked questions about the Covid-19 vaccination programme. The Foundation worked with staff at Morpeth School in Tower Hamlets, east London, before working with Queen Mary University of London and the vaccine confidence project at the London School of Hygiene & Tropical Medicine.
