You might think the flu season is over, but H1N1 flu is still around. Rebecca Williams reports health officials still want you to get vaccinated against the virus:

H1N1 flu peaked in the U-S last October and November.

The Centers for Disease Control and Prevention estimates through the middle of January, 57 million Americans got sick and 12-thousand people died.

Right now, most of the people getting sick with H1N1 are in the Southeastern U-S.

Tom Skinner is with the CDC.

“We wouldn’t be surprised to see activity continue into the spring and early summer. How much activity we may see moving forward into the fall and winter it’s just hard to tell.”

He says anyone who hasn’t gotten the vaccine should. Especially people with the greatest risk of complications from the flu. Those are pregnant women, kids younger than 5 years old and adults older than 65.

This fall, the H1N1 vaccine will be combined with the regular flu shot.

Public health officials want people
to get vaccinated for swine flu.
But only half of parents nationwide
say they plan to get their kids vaccinated.
Many say they’re worried about vaccine
side-effects. Julie Grant reports some
government policies may have inadvertently
made people concerned about vaccine safety:

Some of the schools near where I live in Ohio have absentee
rates of 20%. Kids are reporting flu-like symptoms. Some
schools are even closing down to keep more people from
getting sick.

At the same time, a study by the Harvard School of Public
Health finds that only 51% of parents nationwide plan to get
their kids vaccinated against the new swine flu.

The vaccine has a serious public relations problem.

One reason people are worried: thimerosal.

Thimerosal is a preservative used in vaccines. It prevents
bacteria and fungus from contaminating vaccine bottles.
Thimerosal is almost half mercury, by weight. And that
makes a lot of people nervous.

As a precaution, it was taken out of most American vaccines
about twenty years ago. But it’s still used a lot in flu shots.

Lynn Gregor has two little children. She’s been leaning
toward getting them vaccinated for swine flu.
But she just heard about thimerosal, and she’s concerned.

“Because even if it’s a teeny, tiny bit of mercury, which is
what that product is connected with. Because a teeny tiny
bit of mercury can have a big impact.”

The Centers for Disease Control says the type of mercury in
thimerosal is different than the kind that’s in thermometers.
Lots of people think thimerosal is linked with increased
autism rates. But public health officials say science does not
bear that out.

“There has been no credible evidence of a harm that’s linked
to thimerosal.”

That’s Donn Moyer. He’s spokesman for the Washington
state Department of Health. It’s one of six states that have
passed laws making it illegal to give young children and
pregnant women flu shots that contain thimerosal.

Moyer says the health department didn’t ask for the law. It
says thimerosal is safe. But, politicians wanted to appease
people concerned about thimerosal.

The state of Washington’s concern is not about the actual
safety of thimerosal, it’s about the public’s perception of
thimerosal.

“The goal was to maintain public confidence in vaccine
programs and to encourage parents to have their kids
vaccinated.”

But now that the new swine flu is here, Washington is
suspending its law. The swine flu seems to be hitting young
children especially hard, and Moyer says infants and
pregnant women should get immunized – even if the only
shots available contain thimerosal.

“We don’t see any credible risk of health effect from the
thimerosal and it could protect against a very, very serious
influenza infection.”

That seems like a mixed message to parents. And it’s part
of the confusion between the science and politics of this
issue.

(Fox news music intro)

Anchor: “We are tracking H1N1 and health officials here in
the US…”

On this Fox news report Dr. Kent Holtorf is labeled an
“infectious disease expert”, and he warns people against the
vaccine.

Holtorf: “And it’s been shown to cause autism in children
with mitochondrial dysfunction. It’s controversial, though
highly implicated.”

Anchor: “Would you give it to your kids?”

Holtorf: “I definitely would not.”

Some Right-leaning commentators are sharing their
suspicions about the vaccine from the government. And, on
the Left, one natural health newsletter put out a special
edition warning against vaccination.

This all leaves federal health officials with a big job to do:
use the preponderance of science to convince people that
swine flu is potentially more dangerous than the vaccine and
thimerosal.

The mother we talked to – Lynn Gregor – wants to protect
her kids from swine flu, and she’s thinking about getting
them vaccinated.

“If they don’t get it, I’m going to be really worried all winter.
I’m going to be really concerned.”

But when Gregor hears so many people are opting out of the
vaccine – and that some states actually ban thimerosal most
of the time – she’s not sure what to do.

Salmonella Vaccine Coming Soon?

  • While a salmonella vaccine is in the works, researchers don't think it's suited for countries like the United States (Photo courtesy of the Centers for Disease Control)

Researchers are working on a new vaccine to prevent salmonella poisoning. But, Julie Grant reports, the researchers say it probably won’t help us when we’re faced with salmonella tainted tomatoes or alfalfa sprouts:

Transcript

Researchers are working on a new vaccine to prevent salmonella poisoning. But, Julie Grant reports, the researchers say it probably won’t help us when we’re faced with salmonella tainted tomatoes or alfalfa sprouts:

Salmonella poisoning affects about 20-million people worldwide each year and causes 200,000 deaths. A vaccine might sound like a good idea.

Arthur Thompson has been working on one at the Institute of Food Research in England. His group has found that salmonella relies on glucose for its survival. So they’re designing a vaccine to use that against the bacteria.

But Thompson thinks a salmonella vaccine should not be used to solve a problem that industrialized nations can already prevent.

“I don’t think it would be appropriate really, for something like this. I mean, I think in this case, it’s more a case of preventing the contamination in the first place, really.”

Thompson says the vaccine is better suited for people in developing nations where salmonella causes still causes typhoid fever.

The Great Vaccination Debate

  • There are parts of the country where up to 20% of families are saying ‘no’ to vaccines. (Photo by Bill Branson, courtesy of the National Cancer Institute)

Babies and young children get a lot more vaccines today than they did ten years ago. To most parents, it’s a chance to protect their children from more diseases. But there are pockets of places where lots of people are opting out of vaccines. Julie Grant reports that it has the Centers for Disease Control concerned:

Babies and young children get a lot more vaccines today than they did ten years ago. To most parents, it’s a chance to protect their children from more diseases. But there are pockets of places where lots of people are opting out of vaccines. Julie Grant reports that it has the Centers for Disease Control concerned:

Heather Waltz has a five month old daughter. Most Americans her age have already started a series of vaccinations – to prevent everything from Hepatitis B, to Diphtheria, to Polio.

But Waltz’s little girl isn’t going to get those shots. Her mom worries they could cause things like autism, juvenile diabetes and even cancer.

“I think the jury’s still out, as far as what the research says. But there is enough anecdotal sort of stuff to make me aware and decide that, really, right at this point, vaccinating wasn’t what I wanted to do.”

Waltz is among a small, but growing number of parents who are becoming skeptical of vaccines.

Lance Rodewald is director of immunization services at the Centers for Disease Control.

He says more than 90% of American children are vaccinated. But there are parts of the country where up to 20% of families are saying ‘no’ to vaccines.

“And that’s getting to a rate of lack of protection of children that really can be a fertile ground for the spreading of diseases like measles. And we actually saw that last year.”

In one case last year, Rodewald says a child who wasn’t vaccinated caught the measles in Switzerland and brought it back to Arizona.

“The parents didn’t realize that the child had measles – brought him to the pediatricians office where there were babies that were too young to be vaccinated that got measles. And then that particular outbreak went through four generations of spread, from child to child to child to child before it was able to be contained.”

Measles can cause more than just a nasty rash. In rare cases, it can lead to death. Measles still causes 200,000 deaths around the world. But it’s been almost eradicated in the U.S. because of vaccines.

Rodewald says many parents are concerned about vaccines today because of a ten-year old scientific article that linked the vaccine for measles, mumps and rubella to autism. Rodewald says the science in that article proved to be wrong.

“The authors withdrew their names from the article. But this particular study set off a whole series of concerns about vaccines and autism that, to this day, is still talked about.”

Rodewald says many studies have been done and found no association, no cause and effect, between vaccines and autism.

It’s tough for parents to wade through all the information that’s out there these days. And there are so many vaccines to try to understand. Back in the mid-1990s, children were given 6 vaccines. Today, they’re supposed to get more than twice that many.

Mother Heather Waltz tries to keep up with it all and says she still plans to avoid vaccines.

Waltz: “For every bit of research and every article I find sort of helping me support my point, there’s a million other bits of research and articles saying that I’m a bad parent, or saying that I’m somehow damaging the health of the entire United States by not vaccinating my child. Just this idea that she could be a measles monster and just running around and infecting her classmates with measles or something like that, and that would be a terrible thing.”

Grant: “What do you think when you see that?”

Waltz: “It doesn’t make logical sense to me. Because to me, if you have 30 kids in a classroom, and my one isn’t vaccinated, wouldn’t my child be the one at risk? Not the public’s.”

But even if Waltz’s daughter doesn’t get vaccinated, she’ll probably be safe from these diseases. With so many other kids getting inoculations, most of the U.S. is not fertile ground for them to regain traction.

No Vaccine-Autism Link

Some parents of autistic kids believe that a preservative used in vaccines is in part to blame for their child’s autism. But Mark Brush reports a new study concludes there is no link between the preservative and autism:

Transcript

Some parents of autistic kids believe that a preservative used in
vaccines is in part to blame for their child’s autism. Mark Brush
reports a new study concludes there is no link between the preservative
and autism:


Pregnant women who are Rh-negative receive a shot to prevent disease in
their developing fetuses. Prior to 2003, these shots contained
thimerosal – a preservative made with mercury.


Dr. Judith Miles conducted a study that found no connection between
thimerosal exposure and autism. The study was published in the
American Journal of Medical Genetics. Dr. Miles says her research is
an important clarification for parents of autistic kids:


“I think it’s still important for parents to know, particularly mothers
who are Rh-negative, not to be concerned that this was something that
they somehow had a part in that caused the autism.”


Thimerosal has been removed from most childhood vaccines in the U.S.
However, it’s still used in the flu vaccine – and it’s widely used to
preserve immunization shots for kids in the developing world.

Bumper Crops of Mosquitoes

With above normal rain in much of the country this spring mosquitoes have been heavier in many
areas. The quick warm up after a cool spring has also helped hatch out a lot of the pests. The
GLRC’s Lester Graham reports you only have to step out your door to see the result:


It’s not so much hot days, but the fact that the nights are warmer that’s helping the skeeter broods
hatch out in hordes. I’ve been painfully aware of the mosquitoes this year because I live right next
to a river in a year where there’s been plenty of rain to make little pools of stagnant water
everywhere. It’s a real nuisance.


(sound of mosquitoes)


“I’m in a very hot car and a lot of mosquitoes are trapped in here with me.
(pause) All these mosquitoes got here, just because I opened my hatchback and took
some groceries out, and they just swarmed in.”


(sound continues… smack!)


I don’t like ‘em much. Most people don’t have a very high tolerance for mosquitoes. They’ve
actually studied that. John Witter is a biologist with the University of Michigan who spends a lot of
time in the woods, studying bugs. He says there was a Michigan State University study that tracked
interaction of people and mosquitoes while camping.


“If you have more than about four mosquitoes landing on your body per minute, the people leave
the hiking trail. They go back to their campers because they just cannot handle that annoyance.
So, higher population numbers of mosquitoes, more bites, more annoyance.”


But not everyone, or everything, can get away from the pests. Jenny Barnett works at the Binder
Park Zoo in Battle Creek, Michigan. The zoo is in the middle of a forest. The mosquitoes love it
there.


(sound of birds)


The zoo’s tried to use different kinds of fumigation in past years, but with sensitive animals and birds
like the ones we’re watching there was a lot of concern; and really it just didn’t work.


“With 430 acres and a lot of it being wetland, we didn’t even make a dent on it. So, after a couple
of years, we stopped doing anything.”


The mosquitoes weren’t always that bad, and guests at the zoo didn’t seem to mind that much. A
little mosquito repellant and everyone was good to go.

Then along came West Nile virus. Like a lot of zoos, Binder Park put its birds inside – not good for
the birds – not good for the people who wanted to see the birds. A couple of years after West Nile
was detected, a vaccine that was developed for horses and it was used on birds, too. Jenny Barnett says it
seems to work.


“So far we’ve had success with it and we are continuing to do testing on their blood to check for
West Nile virus and we’ve been successful so far, but we will continue to vaccinate. We’ll
vaccinate our horses, and we’ll always worry about it, but a lot of the birds do have immunities right
now.”


And it’s assumed a lot of people also have immunity to the West Nile virus. They probably have been
infected and didn’t even know it. People with immune deficiencies are at much greater risk, but
many healthy adults can contract it and dismiss it as a summer cold or bad allergies, but health
officials say do what you can to avoid being bitten. Now, they’re not saying that you shouldn’t go
outside. They’re just saying if you do go outside, you should use a mosquito repellant with DEET.
Natasha Davidson is with the Health Department in Ingham County Michigan. She says don’t
douse yourself in repellant. A light spray will do.


“And if you’re applying it to your face, you should really put it on your hands first and then apply it.
And even applying it to children, it’s better an adult put on their hands first and then apply it to a
child.”


Davidson says don’t use DEET on children six months of age and younger, and don’t put it on
toddler’s hands because they’ll just put them in their mouths. Ugh… not good to ingest DEET.
Some advise using a cream based repellant because it doesn’t go into the skin as easily, and stays
on the surface where it can do some good. It’s also a good idea to wear loose fitting clothes with
long sleeves and long pants. I know it’s hot, but it beats scratching mosquito bites for days on end.
Natasha Davidson says even on heavy mosquito years like this one you can help reduce your
exposure to the pest.


“Other things that people can do is to make sure they have no standing water in their yard,
whether it’s at home or at a vacation property. Empty your gutters. Make sure that they’re clean
so that the water flows through. Make sure that you don’t have flower pots that have standing
water in it, old tires, different things like that. If you have a bird bath, change the water in the bird
bath once a week.”


Beyond that there’s not much you can do. Mosquitoes aren’t going away and with a little
preparation…


(sound of spray)


…you should just go ahead and enjoy the outdoors.

You might be seeing more mosquitoes this year. Conditions are right in many areas to see a
bigger than normal crop of mosquitoes. The GLRC’s Lester Graham reports:


The mosquito populations in a lot of places are high this year because of above normal rainfall.
Although you don’t hear as much about West Nile virus these days, it’s still a threat, especially
to those with compromised immune systems, particularly older people. Natasha Davidson is with
the Health Department in Ingham County, Michigan where there’s been a bumper crop of
mosquitoes lately. She says the best prevention is avoid getting bitten:


“Well, you want to make sure you’re wearing an insect repellant. And also when you’re outdoors
when mosquitoes are active been dusk and dawn, wear long sleeves; wear long pants; wear
socks. And apply the insect repellant to your clothing.”


So far there’s no West Nile vaccine for people. Researchers are working to come up with one.
They believe healthy people who’ve already contracted the virus and built up antibodies might be a
source for a successful vaccine in a couple of years or so.

Relief on the Horizon for Allergy Sufferers?

A new vaccine that reduces food allergies in dogs could

A new vaccine that reduces food allergies in dogs could some day help people who suffer
dangerous reactions to food like peanuts, milk and wheat. The vaccine is also more
evidence in support of the so-called “hygiene hypothesis.” The Great Lakes Radio
Consortium’s Tracy Samilton reports:


Allergies to foods like peanuts have become much more common over the past 20 years.
Some researchers believe it’s because, as a hygiene-conscious society, we’re no
longer exposing our bodies to infections that stimulate the immune system and protect
us from allergies. Pediatrician Dale Umetsu of Stanford University mixed a component
of Listeria bacterium and peanuts into a vaccine. He then gave it to dogs
with allergies so severe that one peanut made them sick.


“After the treatment, the dogs could tolerate up, on average, to 30 to 40 peanuts,
so this was quite an increase and the effect lasted several months, at least,
after the treatment.”


Umetsu says it could be five years or more before a vaccine is available for human trials.
A vaccine could help millions of people with food allergies.

Raccoon Rabies Making Its Way West

Raccoons from East Coast states are spreading rabies westward… and health officials say some animals are getting past their immunization barrier.

Raccoons from East Coast states are spreading rabies westward… and
health officials say some animals are getting past their immunization
barrier. That could be bad news for other Great Lakes states,
particularly Indiana, Michigan, Illinois, Wisconsin, and Minnesota.
The rabid raccoons are a threat because they can bite dogs and cats…
and those animals, in turn, can bite humans. The Great Lakes Radio
Consortium’s Bill Cohen reports:


For seven years, Ohio has tried to keep raccoons with rabies on the Pennsylvania side of its
border. Airplanes and helicopters have dropped vaccine-laden biscuits for raccoons to eat… to
immunize the animals and stop the spread of the disease westward. But now comes word that two
rabid raccoons have made it past the 25 mile-wide immunization zone.


Kathleen Smith is a veterinarian for the Ohio Health Department. She notes the biscuit drops are a practical tactic in an area that’s hemmed in by Lake
Erie and the Ohio river… but if the disease pushes deeper into Ohio, the
immunizations won’t be practical… and states to the west will be infected.


“If it gets past our barrier, northeast Ohio, it would be too cost prohibitive to use the oral vaccine to
stop it from spreading out of the state into the Midwest.”


Officials are asking northeast Ohio residents to tell them about any dead raccoons they spot,
even road kill, so authorities can try to figure out how the disease is moving westward.

Common Vaccines Contain Toxic Chemical

When you go to get your flu shot, there’s a good chance you’ll also be getting a dose of a toxic chemical. The Great Lakes Radio Consortium’s Lester Graham reports:

Transcript

When you go to get your flu shot, there’s a good chance you’ll also be getting a dose of a toxic
chemical. The Great Lakes Radio Consortium’s Lester Graham reports:


Thimerosal long has been used as a preservative in vaccines. But it contains mercury, and mercury
is not good for anyone. In children it can damage intellectual and nervous system
development. The mercury preservative has been removed from many vaccines, but Barbara Loe
Fisher with the National Vaccine Information Center says it’s still used too often.


“We still have it in influenza vaccine, diptheria-tetanus, some hepatitis B vaccines. Those are all
given to children. And there’s a pneumococcal vaccine that’s given to sick children that also has
Thimerosal, so, you know, on any given day a child could get more mercury than they should be
exposed to because the manufacturers just haven’t gotten it out of all the vaccine.”


Loe Fisher says manufacturers can produce the vaccines in single dose vials, eliminating the need
for the preservative, but the pharmaceutical companies have been resistant because it’s cheaper to
produce multi-dose vials with the mercury preservative.


For the Great Lakes Radio Consortium, this is Lester Graham.
