COVID AND THE VACCINE - TRUTH, LIES, AND MISCONCEPTIONS REVEALED, page-83912

Can someone please explain this.-

My mate lives in a share house that the entire house of 4 men , 3 women and a child all contacted Age group of the adults 25 to 32 and child is 3 years. old.
The entire house contacted Covid last month (test results for all were positive).
Of the people only two of the men were vaccinated, one 2 doses and the other 2 and a booster, the rest unvaccinated and the child also unvaccinated.

The household was extremely sick and in a bad way , one of the men and all 3 of the ladies were struck down for 2 weeks bed ridden basically.

I know these people from social interactions , particularly one of the guys and one of the ladies are very close friends. They are extremely fit, most engaging in sport weekly in one way or another.

Now the two men that were vaccinated showed basically no symptoms whatsoever even though they tested positive as well, and the child a runny nose for 1 day.

The unvaccinated were basically as sick as they had ever been i was told, so what is the go here ?

To me it seems the vaccines are doing their job, keeping symptoms at bay, it does show all the unvaccinated were extremely sick bar the unvaccinated child.
