This website has an agenda, and is an anti-vaccine website. So I do not trust the information presented there, unless I can verify its credibility elsewhere, where there is no agenda.
Whether to vaccinate or not, is an individual choice, and should remain that way. Those who choose to vaccinate, take risks, those who choose not to vaccinate, take risks. What people don't have the right to do, is endanger the lives of others.
If the anti-vaccine promoters have to rely on lying, to try and push their agenda, then their cause is lost.
Lying is exactly what they are doing, IMO.
I know my chemistry and biology, so the lies of the anti-vaccine promoters are easy to spot. I would encourage everyone to do their homework, and not get carried away with the emotive lies of those with an agenda.
