however, this is a state issue, and that seems to be the problem . cdc is doing the very best that they can to try to convince every state. we are at the bottom. or not at the bottom, very close to it area and i am very concerned about it, but at least the media, i think, today at least realizes that one study which was totally discredited there should be a very strong statement by everybody involved that they should go ahead and get these vaccinations so i strongly recommend that, and i thank you for your leadership. >> thank you, senator roberts. we will now go to senator baldwin. i want to mention again to the senators that at 11:00, we are going to excuse dr. schuchat and caught a second panel, but anyone who has not been able to ask a question will be the first one up. senator baldwin? >> thank you, mr. chairman, and i also want to thank you for holding this hearing. it has reduced human suffering and saved lives by preventing and reducing the outbreak of preventable diseases, and thanks to national policy, including the affordable care act now mill

the last thing we need to give the cdc is more input. r primary role should have been telling parents to get vaccinated and to really dispel the myth between vaccines and autism, which was an issue of scientific fraud. the medical researcher manipulated -- >> you know tom, that information is out there. it's on the internet. and it is sticking with parents. >> a law is not going to change that. but educated people on tv can. that's where it needs to be done education. >> the thing is there are pockets of unvaccinated children in marin county. which has one of the highest education rates and one of the highest financially, they are well off. the cdc has a superb website on measles. >> and it tells you will exactly -- it's the one study that connected autism with the vaccine was debunked in 2010 and that you must vaccinate your children. it's not the here's is your brain on drugs ad. it's not a sexy campaign. maybe they need to do. that but i think we've got to understand that this is a federal challenge. >> the cdc has been spending time o

however this is a state issue. , that seems to be the problem. cdc is doing their best to try to convince every state -- mississippi leads. we are at the bottom. not the bottom, but fairly close. i'm very concerned about it. at least the media realizes that one study which was totally discredited -- there should be a strong statement by everybody involved that they should go ahead and get these vaccinations. i strongly recommend that and i thank you for your leadership. >> thank you, senator roberts. i want to mention again to the senators, at 11:00, we will call the second panel for 15 minutes. any senator who has not had a chance to ask a question will be the first one. >> i want to thank the ranking member for holding this hearing. our nation's vaccine program has greatly reduced human suffering and saved lives by preventing and reducing the outbreak of preventable diseases. thanks to national policy , including the affordable care act commit millions of families have access to free immunization. i'm concerned about the recent measles outbreak and

it is now, according to the cdc one in 68. that is looking at eight-year-olds and four years to do the study. we don't even know what the rate is among two euros off -- two euros. to say vaccines could be playing no role, my view, is reckless and responsible. in our book, we include 20 abstracts. there is good science that shows how plausible a connection is but it needs more rigorous study. >> yet mentioned the importance of the schedule of vaccines. it is not so much certain vaccines necessarily not begin it all, but that they be spaced differently. >> there's that a lot of rigorous science showing why the schedule is what it is. the way vaccines are tested before their recommended and then mandated is, there tested individually, not tested as a schedule. as senator rand paul says, he criticized the recommendation and the mandate in most states for hepatitis b shot for infants one and two days old. hepatitis b essentially transmitted. what is the rationality for giving a baby a vaccine that will wear off by the time they are

the cdc changed the recommendation because they found that day care centers were a site of transmissionr populations of people not vaccinated in those areas. dr. bob sears, thank you for coming on, i appreciate you coming. >> thanks for having men on, chris. let's turn now to the ceo of community health tv. doctor, i know you do research and work in this area. this idea, there is an intuitive appeal, delay some by a month. what's bad about that? >> there are a couple of things. what we must always realize is this is about preference. we think about parental preferences, they're based on emotion and not science. we know that of four million kids will get combination vaccines this year alone, and it's 1.1 in 1 million will have a serious adverse event or injury. the chances of you taking a aspirin and having a hemorrhage are greater than a vaccine injury. sears mentioned a registry. people can report vaccine injury and adverse reactions to this. not only can doctors do it, but parents and teachers can do it and there is no cause and effect. if i get a flu vaccine, and i walk out to the st

today directors at both the cdc and nih spoke to congress. >> you have one of the most highly effective vaccines against any virus and you have a highly contagious disease, measles that, can have serious complications. so to me it's really a slam dunk what the decision should be. >> many parents don't realize these diseases are still out there and if their children aren't vaccinated, they'll come back. so with the measles outbreak i think most parents who weren't vaccinating didn't realize measles was still around and could be dangerous. >> the vaccination debate is fast becoming a hot topic among 2016 presidential hopefuls. republicans chris christie and rand paul support vaccinations but still say parents should have a choice. democrat hillary clinton had responded to a questionnaire in 2008 while running for president she would support investigating vaccines as a possible cause of autism, but today democrat hillary clinton tweeted the science is clear. the earth is round. the sky is blue and #vaccineswork. most states have laws that require the measles and other vaccination, but some

our centers for disease control and prevention, the cdc has put out health alert networks. they're constantly trying to get the message across. they are doing very good job. but sometimes as much as you talk you don't turn people around. but you shouldn't give up. also it isn't just people who have deep philosophical problems with vaccinations. there are some people for reasons that are not as deeply fill cough call that you can get to and turn them around. that is what i think the cdc is doing and doing a very good job but they also work very closely with the local and state health authorities. it's that synergy and collaboration between the federal government in the form of the cdc and fda and nih and local and state authorities. >> schieffer: shoeshine who have not been vaccinated be allowed to go to public schools? >> that's not for us to decide. what we can do is just what jon said. is that get the information about, you have a very good vaccine, you have a highly contagious disease, you have the disease that is entirely preventable. when you look at that data with the

and that seems to be the problem. cdc is doing the very best that you can to try to convince every state. mississippi leads, we're at the bottom. not at the bottom but, you know, fairly close to it. i'm very concerned about it. but at least the media i think today realizes one study that was totally discredited that there should be a very strong statement by everybody involved that they should, they should go ahead and get these vaccinations. so i strongly recommend that, and i thank you for your leadership. >> thank you, senator roberts. we'll now go to senator baldwin, and i want to mention again to the senators at 11 we're going to excuse dr. schuchat and call the second panel for 15 minutes. but then any senator who hasn't had a chance to ask a question will be the first one, first one up. senator baldwin. >> thank you, mr. chairman. i also want to thank ranking member for holding this hearing. our nation's vaccine program has greatly redawessed human suffering -- reduced human suffering and saved lives by preventing

the cdc has been supporting 35 states to set up building practices so leading issue is people need to get vaccinated in a public health clinic, that health clinic will build the insurer, we are trying to make sure the scarce federal dollars for the the insurers to pay their way. >> in the home state vaccination worldwide, the gates foundation, and the reality is we are incredibly lucky to have people who have witnessed death by disease like measles or polio or whooping cough. i know you have worked with these issues across the globe. can you tell us what you perceive are the key challenges to achieving optimal immunization rates as opposed to developing countries? >> we are fortunate to have a strong health system and access to vaccines. in many countries even with the lines that provide vaccines for free for the poorest countries the infrastructure is very weak so strengthening health systems overseas so they can deliver vaccine is vitally important. there are a number of public/private partnerships helping in that arena and i want to mention the measles rebel initiative, responsible

the cdc is going to be here on capitol hill today. the director of communicable diseases will be here answering questions about how do you track this and how do you stop it. they're going to hear today from a pediatrician whose written a letter about getting the shot. the mmr. the shot against measles. his kids were exposed but they cannot get the shot. there are a lot of people that are comprised or for other reasons cannot get the shot. we have a brand new pugh research poll where 83% of americans say that do believe that the shot is safe. but there are a lot of communities now including the district that are dealing with what the cdc said are confirmed cases of measles. >> tracie potts live on capitol hill. thank you. >>> 12 minutes before the hour. leaders looking currently at the measles outbreak. montgomery's leading health official updates the council on the threat of measles in montgomery county. they'll hear an update on childhood vaccinations. >>> voting on using artificial turf. it would be the seventh school in the county t

but tonight, the cdc warning it's not just hospitals anymore. let's get right to dr. richard besser. where else can you get this? >> reporter: well, hospitals are the number one place people are picking it up. but not everyone's getting it there. so, the cdc is doing a study to see, can you get it in a doctor's office? in a dentist's office? they don't know for sure yet, but what you can do to be safe, before you leave the doctor's office, wash your hands with soap and water. you have to use that, because alcohol sanitizers don't kill c-diff. >> okay wash your hands on your way out of the doctor's office. rich besser with us tonight. rich, thank you. >>> we move on now to a big move this evening by the fcc, voting to implement new net neutrality rules, as they're called. a move that will make internet service providers subject to regulation. the decision drawing sharp criticism from republicans, including house speaker john boehner, who warned it could hurt the u.s. economy, saying, quote, overzealous government bureaucrats should keep their hands off the internet. ton

. >>> a new and scathing statement from the cdc. e the outbreak of measles was first reported back in december at disneyland a highly contagious virus has spread to 14 states and 102 cases. this anti-vaccination movement and debunked study have seen vaccination levels declined. the director of the cdc saying this. the signs of this is very clear. there was one study that has since been shown to have been fraudulent that alleged to show problems but study after study, review after review independent agencies emphasizes that there are no long-term adverse consequences from the measles vaccination. how worried is the cdc about this elizabeth cohen, and what can they really do about it? >> brooke they are pretty worried that it's going to grow. measles is so contagious that there's not a great way of stopping it. most people recover from the measles just fine but there are people who died. hundreds of people died every year from the measles. brock, you're asking what can be done about this? i would have to say, having spent an evening wi
