Winter weather forces us to congregate inside but evidence suggests cold, dry air also helps spread respiratory viruses.
Natural herd immunity is a myth. It is not something that can be achieved by natural infection. Without a vaccine, the virus could become endemic, permanently present in the population.
Whether a coronavirus vaccine involves a live virus or a carrier organism, it will probably require more than one injection. But that is not a bad thing.
