A significant hurdle to achieving this, though, is that the fastest a vaccine has ever been developed, the mumps vaccine in 1967, took 4 years. Risk in vaccine research and development quantified. Across all industry-sponsored vaccine development programs, we can see that monkeypox vaccines have had the most developmental success, followed by rotavirus and Japanese encephalitis vaccines (see Table 1). DNA vaccines see high Phase I failures as expected, and therapeutic vaccines have lower success rates than prophylactic vaccines. This site needs JavaScript to work properly.
