Scientists have the tools and knowledge to develop safe, effective vaccines, from trials to vials. This resource addresses the process by which vaccines are designed, tested and regulated. Key concepts include 1. Mechanisms of immune recognition for SARS CoV 2 2. Vaccines vs therapeutics 3. Vaccine types and sources - nucleic acid, viral vector and attenuated/inactive vaccines 4. Vaccine development pipeline 5. Exploratory research and vaccine design for SARS-CoV-2 - spike protein target 6. Vaccine production 7. Testing and clinical trials 8. Challenge trials 9. Regulatory review and approval
