Hilda Bastian Hilda Bastian (npub1cjn…05q3) has an extensive database of all the different covid vaccines. Well worth following. Some nasal vaccines are in phase III trials now. Some are approved (India, China, Iran, and?) but none from WHO top tier regulatory bodies. Periodic summaries of covid vaccines also on her blog: e.g. https://absolutelymaybe.plos.org/2024/07/31/more-signs-of-broad-protection-from-next-generation-covid-vaccines-update-19/
