Why do millions of of kids get injected with vaccines that make them infertile?

I have been reading a lot of articles regarding vaccines and the government this the government that. The only place that most people get vaccined and need to is in the U.S I mean in other countries like Mexico people really don’t get injected who knows what in them. I mean how do we really know what they are injecting our babies is really good for them? How do we know that’s not one of many reasons that causing us to get sick within time cancer or other diseases. How do we know the government is not spraying and giving us shit to kill all us. People follow what they say is right to do. People stay woken that’s all
