I found a website talking about vaccines killing people. are vaccines really dangerous?

No!: What you read is complete nonsense. All you have to do is compare the rates of infant mortality, not to mention life expectancy, between the pre-vaccine and post-vaccine era to know that vaccines save lives. Before the vaccine era, parents expected to lose children to diseases that we now consider preventable.

No: There is no law against making up the most preposterous untruths as long as they're not on a medicine bottle. The links from these sites to big-money health frauds are clear. You also have a responsibility to your neighbors to maintain herd immunity. When i was a kid, we watched other kids get brain damage or die of diseases that today's kids have never seen -- thanks to immunization.
