Hoping not to offend anyone? The primary thing that those who HAVE been fully vaccinated must remember:
Those that, for whatever reason have NOT been vaccinated, are literally ZERO threat to you. Just me - I would worry more about a drunk driver, or some new terrible thawed Tyrannosaurus to human plague . The protection stats on current vaccine are literally astounding. Really hoping we can get a Flu vaccine, using the same technology.
Please - if willing and able? Get vaccinated. Then let Nature solve the remaining issues. Nature is very good at this.
As a specific individual, no they aren't much threat. As a population then sort of - as COVID spreads and mutates, rather than being extinguished, it can create vaccine escape variants.
