At this point in the pandemic, we ought to be able to both offer boosters to the most vulnerable ahead of the winter and increase the pace of vaccine rollout across the world.
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.
