  1. The gold standard will be a viral vector nasal spray vaccine, coming some time in 2022, possibly from AZ. It develops an antibody response where the virus actually tries to enter the body. Due to this Oxford wins the long game as mRNA is too fragile for a nasal spray and can’t survive room temperatures.
