Look if both households are low risk and everyone has been vaccinated go ahead and meet under one roof without any masks and hug - that's fine under current recommendations. It's even looser than that, like if you unvaccinated low risk children visiting vaccinated grandparents ad so on.
Right now across US being fully vaccinated is only 80% effective against infection. When you have 20k vaxed folks meet when the virus is endemic in the pop, some of those vaxed folks will be infected and some will catch it there.
When more folks are vaxed there will be less of the virus circulating and then that calculation then changes. It's all about how prevalent the virus is in the community to begin with assuming no strains appear that dramatically reduce the effectiveness of the vax.
We've never taken such an attitude for any other endemic respiratory pathogen in existence, and for good reason. It's completely absurd and ignores not only the important health benefits of regular social contact, including direct physical contact, as well as the literal benefits of exchanging pathogens with others.
You and the other commenters arguing your "side" also seem to completely ignore the phenomenom of natural immunity, which I think very obviously has been fallaciously denied by "experts" precisely because they want to convince everyone in the world to get this vaccine. They're already talking about yearly booster shots because most people's mental models are from Flu which has a much greater space of possible genetic configurations, whereas SARS-2 is relatively constrained in how it can evolve and thus should not need a yearly booster if this weren't just about making absurd amounts of money (which it is).
In any case, you should know that there are people like me - very much in the minority - who refuse to submit to such absurdities and will keep fighting. We will continue to be literally as well as metaphorically discriminated against until your "side" stops brainwashing people into a completely disproportionate response to an endemic respiratory virus.
You can stay inside with a mask on while vaccinated all you want. Be my guest. But please stop advocating for and/or supporting mandates and restrictions on the rest of us who have not caught your specific strain of agoraphobia, germaphobia, OCD and misanthropy.
Sure we will get natural immunity, the difference between other diseases respiratory or otherwise is its effectiveness in killing people combined with its transmission. It is in the Goldilocks zone for deadliness and transmission , highly deadly diseases like Nipha or Ebola are easier to keep from being an pandemic precisely because they are so deadly. They still require a strong and immediate response to keep it in control and local.
The annual flu shot is not just for you, it is also to prevent you transmitting what is probably harmless to you but deadly to immuno-compromised like the elderly, they don't have ability to get natural immunity. Pneumonia is significant cause of death amongst senior citizens.
If 600,000 people dying U.S alone in the last year, does not convince you to stay masked and safe and follow some simple instructions for few more months until everyone is vaccinated even if you don't believe in them personally, nothing is going to.
