Schools to receive free resources to challenge Covid-19 vaccine conspiracy theories. (PA/Canva) Schools are set to be given free teaching materials to help challenge Covid-19 vaccine 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. It is hoped the move could help tackle hesitancy to take the jab in some communities. Available as a PowerPoint presentation, 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, who initially devised the materials.
