As others have mentioned here you pass it along vaccinated or not.
You can also have the vulnerable population take precautions, not the young population. To be frank what kind of sick society pushes the young population to take on risk (novel vaccine incomplete clinical trials, rare heart inflammation issues documented, spike protein membrane break off issue, etc) to protect the elderly population? This is the first time societies have ever called for risking the youth for the elderly and it's not morally right.
