Besides my love for horses and cars, I am passionate about making the cheapest vaccines in the world. I started making life-saving drugs when I was 22.

I'm very pro vaccine. I get all six of my kids vaccinated. I believe vaccines save millions of lives, and people ought to be getting vaccinated.

Vaccines are the tugboats of preventive health.

I have heard of many tragic cases of walking, talking, normal children who wound up with profound mental disorders after vaccines.

Clearly, some of the reason people embrace alternatives and reject vaccines is that they are angry and mistrustful of government and of pharmaceutical conglomerates. More than that, we pay too much for health care, it's not good enough, and the system is too complex. We need alternatives.

If you Google some sites about the link between vaccines and autism, you can very quickly find that Google is repeating back to you your view about whether that link exists and not what scientists know, which is that there isn't a link between vaccines and autism. It's a feedback loop that's invisible.

Why do other first world countries give children so many fewer vaccines than we do? Vaccines save lives, but might be harming some children. Is moderation such a terrible idea?

I have seen this happen in recent years with regard to pharmaceuticals and vaccines, where, working together, we are improving access to medicines and vaccines for infectious diseases in the poorest countries.

With infectious disease, without vaccines, there's no safety in numbers.

Thimerosal is a mercury-based preservative that was in many American vaccines until 2003. It was removed from many of the pediatric vaccines, but it was put in the flu vaccine, which is now given to 53 million Americans.

But we might be talking about a significant percentage of parents that have questions about vaccines - and we need to answer them. We need to give them the scientifically based, credible answer.

Vaccines save lives, and I urge all Americans to continue their plans to get vaccinated as soon as possible.

Vaccines are the most cost-effective health care interventions there are. A dollar spent on a childhood vaccination not only helps save a life, but greatly reduces spending on future healthcare.

The simple truth is, the short-term solution is for the FDA to allow more importation of safe vaccines from other nations. But the long-term solution is to get more vaccine production within the U.S.

It doesn't seem to matter how often vaccines are proved safe or supplements are shown to offer nothing of value. When people don't like facts, they ignore them.

You can have the best vaccines for a woman or her child, but if you can't get her to come and get them then they won't work.

Vaccines are great and masks have a place, but state coercion is not where America wants to go.

How is it that mercury is not safe for food additives and Over the Counter drug products, but it is safe in our vaccines and dental amalgams?

I think there's no question that vaccines have been absolutely critical in ridding us of the scourge of many diseases - smallpox, polio, etc. So vaccines are an invaluable medication. Like any medication, they also should be - what shall we say? - approved by a regulatory board that people can trust.

The thing is I think vaccines are one of the greatest medical breakthroughs that we have. I'm a big fan and a great fan of the history of the development of the smallpox vaccine, for example.
