holland has about vaccines. she says, that vaccines were never tested together.urse they are tested together. you cannot put a new vaccine on the schedule without proving that you are vaccine doesn't interfere with the safety profile of existing vaccines and vice a versa. ms. holland says there have been no studies looking at relatively vaccinated or unvaccinated children. that is not true. there are several studies that have looked at that, including one that suggests the highly vaccinated child has better health and the child who is less vaccinated. ms. holland says the hepatitis b virus is all he transmitted by sexual contact. that is not true. children less than 10 years of age in this country before the hepatitis b vaccine, 18,000 was ever. half guided by traveling through birth canal those infected with hepatitis b, the other got up from relatively casual contact. those children who are less than 10 were not getting it from tattoos are using intravenous blood transfusions or drugs, and they certainly were not getting it from sexual contact. there are gettin

not vaccinate. it is the philosophical exemption that is causing the problem. i think it is driven by misinformation, so i certainly am in favor of eliminating such philosophical exemptions. the state senator in california just introduced a bill last week to do just that and i am certainly going to be supporting the effort in california. >> levy suggests an alternative to the elimination of the exemption, as you mentioned, all you want do in a state like california or connecticut is sign a piece of paper and you get no information on the consequences of not getting a vaccination. if the studies are pretty clear that more information you give the less likely it is that people take the exemption. if that, the less likely you will have outbreaks. this is a stunning one from 2006, in states that have higher bars for exemption, they were 50% less likely to have whooping cough outbreaks. let's say we just raise the bar for a philosophical objection and we said for instance, you have to consult with your p

the trends in vaccination are that almost everybody's getting vaccinated with most of vaccines state by state there are differences in particular vaccines. mississippi has a, today not allow personal -- does not allow personal belief exemptions and many people feel that the only exemptions that ought to be allowed are medical ones because, of course some children can't get vaccines because of -- >> and i'm not here trying to get into it. what i'm trying to get into is the epidemiology -- >> right. >> that where there are high rates of compliance, how does that correlate? >> there's no correlation between vaccination uptake and autism. >> and you have the epidemiology to support that. >> right. >> which then goes exactly to outreach and education. now, i'm going to go to a different -- because i really think, and i think the committee ought to really think about our efforts in the area of awe touch. i -- autism. i know we've been very focused on issues related to alzheimer's and other issues, but it really is an epidemic in our country. and mothers will to anything -- and fathers as w

of vaccinations. this is a collective effort. it's for the common good. we're all benefited from it. we've substantially minimized things like polio, rubella, chicken pox and many serious illnesses and we have to change the expectation. you get your kids vaccinated unless there's a good health reason they shouldn't be vaccinated not just because i don't like it. >> at what age should infants be vaccinated? >> well actually this is a situation of where you don't vaccinate infants at the two-month or four-month mark but at the year -- i mean two immunizations and it's the year and 15 months. >> and at that point, do you think adults also should get booster shots? who should get this booster? >> well that depends upon when you were last vaccinated and whether you remember whether you were vaccinated or not. getting the booster is not -- it's not harmful. so on the extra precaution, if there's a lot of uncertainty about your situation, you probably should get it. and again, i think a large part of this is

vaccine as opposed to for example the influenza vaccine. but we have nonresponders who won't mount the response to the vaccine and there are always going to be those nonresponders with any vaccine. so hurt immunity is so important that they're all protected by the immune population as a whole. >> i want to play awe statement from rand paul considered to be a possible presidential candidate in 2016. and he's a practicing physician, here's what he just said about vaccines. >> i've heard of many tragic cases of walking, talking, normal children who wound up with profound mental disorders after vaccines. i'm not arguing vaccines are bad idea i think they're a good thing. but i think the parents should have some input, the state doesn't own your children, parents own the children and it is an issue of freedom. >> he's touching on exactly what parents fear -- rational or irrational but he's talking about it. can parents ever have a choice when it comes to vaccines? or is that a bad idea? >> it depends upon the context and what disease you're talk

aren't vaccinated. should you send your child to school -- >> well, he should be able to send his kid to any school he wants. the question is, should the ones that are not vaccinated to come and contaminate his kids. and that's the big debate -- >> let me ask you marc a medical question because i think this is also big deal. people are saying some of the ones that got measles, they had the vaccine. so what's the answer to that? >> and why should i get this? >> that's a great question, david and that makes the answer even more to the point. because of what you said at the beginning, 10% of the time we can't even be sure that the vaccine is going to give you a permanent immunity. so even if you had the vaccine, there's a small chance your kid is going to be at risk if someone unvaccinated is paraded into the school. >> so this is a numbers game. >> immunocompromised can't get the vaccine. we can't give it to somebody with hiv. >> so it's not 100% guarantee just because you got the vaccine but it works in
