In other words, according to the new definition, a vaccine does not produce immunity. The recipient can still get sick, but allegedly the illness will not be as serious. This means that vaccines do not keep people from spreading the disease, either. It would be nice if the COVID-19 vaccines actually did provide some level of protection, but data out of the UK shows that this might not be the case.
