Can a healthy person spread the flu to others without having symptoms themselves?

Can a healthy person, who gets exposed to a sick person with flu, and not get sick themselves and for that matter, never gets a flu shot, go over to those with lower immunity to infectious diseases and spread the flu to those other people, as if they were a flu carrier of sorts? Lets just Google it. Question "Can a healthy person spread the flu to others without having symptoms themselves?" Answer YES And it BEGS THE QUESTION Should it be made law that all persons be given the flu shot? Then, would that go against certain ethics? I figure it must because nobody took a gun to me and insisted I go get the shot. I did it willingly, but those I know, some, who claim never to have gotten the flu in their lives, just the sniffles, a cold or mild case of the 24 hour bug, insist they have become stronger by not getting the shot and those who get the shot are, in their opinion, in many cases, apparently, those who receive an annual flu shot to prevent it from making them sick that following flu season, are simply weak. Yea, right. I think not. It stands to reason that it is those who don't bother getting a flu shot, who insist they don't need it that the flu has become more deadly. MY 2 cents. And in this year, 2018, what are the numbers of those who have become to the latest strain of influenza in all our history? https://www.forbes.com/sites/stevensalzberg/2018/01/21/this-years-flu-is-nasty-and-getting-worse-and-now-weve-shut-down-the-cdc/#32678dde1144
