As measles cases continue to increase nationwide following an outbreak at Disneyland, doctors are urging parents to learn the facts about the Measles Mumps and Rubella (MMR) vaccine.

27 counties in California still have dangerously low kindergarten vaccination rates, and statewide the percentage of kindergartners with personal belief exemptions has been rising steadily since 2002.

Dr. Dennis Woo, a pediatrician at UCLA Health Santa Monica, has been fielding calls from worried parents.

“I am convinced that most people make this decision not based on fact but on feeling.” Dr. Woo said, adding those feelings are influenced by what parents have heard from friends.

Carrie Swearngin, mother of a two year old boy, said she has friends who urged her not to vaccinate her son Samuel.

“They were in our ear about it a little bit,” she said.

Friendly advice aside, what does the scientific evidence actually show about the safety of the MMR vaccine?

“Facts are that many studies have been done to look at the safety of vaccines, and they’re looking at large populations of children and it’s been determined that… autism is not caused by the MMR.” Dr. Woo said.

The American Academy of Pediatrics has a detailed list of those studies with links to the published results.

Among them, the Centers for Disease Control (CDC) conducted a study comparing rates of vaccination among thousands of children, some of whom had autism, and others who didn’t have autism. The study found similar rates of vaccination between the two groups.

Other studies have looked at the effects of thimerosal (mercury), a vaccine preservative that some parents believed caused autism.

A scientific review by the Institute of Medicine (IOM) found no connection between thimerosal-containing vaccines and autism. Nevertheless, in 2001 thimerosal was removed or reduced to trace amounts in all childhood vaccines except for one type of influenza vaccine, for which alternatives without thimerosal are available upon request.

“We effectively have removed mercury or thimerosal from all the children’s vaccines and we have not seen any drop in autism. So clearly, autism is not caused by thimerosal,” Dr. Woo said.

Other parents voice a concern about kids getting too many vaccines at once, and whether all of them are needed.

A 2013 study published in the Journal of Pediatrics looked at this concern of “too many vaccines too soon.” The study examined the medical records of about a thousand children, how many vaccines they got, and found no connection between the number of vaccines they got, and whether they developed autism. Researchers also note that the amount of antigens (immune stimulating material) in modern vaccines is much lower than those in older vaccines used in the 1990’s.

“Children’s immune systems are well suited to be able to tolerate all that,” Dr. Woo said.

The MMR and autism scare was sparked by a 1998 study by British surgeon Dr. Andrew Wakefield, which linked the MMR vaccine to autism. The study involved only 12 children. The British Medical Journal launched an investigation into the study and found numerous problems in the way it was conducted. It also found that Wakefield was paid $600,000 by lawyers trying to sue vaccine manufacturers. Ten of the 13 author withdrew their support for the study’s conclusions.

In 2010, the medical journal Lancet completely retracted the study. A British medical panel concluded that Dr. Wakefield had been dishonest, and violated basic research ethics rules. British regulators revoked his medical license, saying he was guilty of “serious professional misconduct.”

After weighing the evidence, Swearngin went ahead and got her son vaccinated.

“He’s all set,” she said. “We’re of the mind frame to listen to the doctor.”

The current MMR recommendation is that children get the first shot at 12-15 months of age, and the second shot between 4-6 years of age. Dr. Woo said that if your child is up to date on the first MMR shot, there is no need to get the second shot early, unless there was a known exposure to measles.

Each vaccine insert (The big ass paper of warnings that come with each box of vaccines) says right on it, "This vaccine has not been evaluated for carcinogenic or mutagenic potential or fertility" Hmmmmmm, how you like that? Even crayons get tested for frikkin' cancer!!!!!!! But not the shots that we are shamed into getting? Most of today's vaccines were designed in the 60's!!!!!!! Sheesh, you pro-vaxxers are so brainwashed. Measles rates went down in the from the early 1900's to the 1940's, BEFORE THE VACCINE CAME OUT!!!!!!!

TheRealShroom says:

Vaccine companies can't be sued. They have "legal immunity". Just look up the VICP (Vaccine Injury Compensation Program) End of debate

umm why are non anti vacciners panicking? their kids are safe, right?

A good citizen for what believing your bullshit when the first study proved that it does cause autism

The Canine Nutritionist says:

Thirty-five cases of the measles is NOT a state of emergency.

It’s thirty-five cases of the measles.

In the vast majority of cases, the measles is nothing more than a fever and a rash. That’s it.

Watch old episodes of The Brady Bunch and see what people thought of
the measles before the vaccination campaigns began. “If you have to get
sick, you sure can’t beat the measles!”

If you’re alarmed and
worried for the newborns and immune-compromised, then PLEASE, keep your
children home after you vaccinate them with a live-virus vaccine, like
the MMR. Your children can shed and transmit the infection to those with
weaker immune systems up to 30 days following vaccination.

your child does get the measles, stay home, keep them hydrated, and
increase their uptake of Vitamin A. Learn about homeopathy and essential
oils if you want more tools in your toolkit.

Then, celebrate
that they will have lifelong immunity that can be passed on to their
babies via breastmilk. If treated naturally, they’ll also have less
heart disease, arthritis, allergies, autoimmune diseases, and cancer in

Thirty-five cases of the measles is NOT a state of emergency.

You know what is?

Thousands upon thousands of children suffering from chronic diseases
that are passed off as “normal” vaccine adverse reactions. (Learn more
in the comments!)

When the media really does its job and reports
what’s really happening rather than manipulative pharma propaganda, then
it will be worth watching.

In the meantime, turn off the news.

And stand up to protect your rights.

These news “stories” are nothing short of sales campaigns and always
precede up-and-coming legislation meant to make vaccines mandatory for

Kids should not be vaccinated before 3 years old. And this doctor is brainwashed as fuck

Dr Stephanie Seneff. Check her out. This guy is a liar.

Vaccines cure autism.

OMG look at all the antivaxers im losing hope in humanity

Slayer Death says:

You need to get vaccinations and people who don’t vaccinate THEIR KIDS are just fucking dumb


ALL VACCINES are SORCERY and WITCHCRAFT POISONS……. don't fall for these lying brainwashed big pharma puppet doctors, nurses and pharmacists…….. LEARN WHAT IS IN THE POISON VACCINES PEOPLE !!! Connect the DOTS why we have EPIDEMIC Diseases today, especially in the children…… Learn why U.S.A. has the HIGHEST RATE of SIDS…… SUDDEN INFANT DEATH BY VACCINES …….

I think not.
"Yes, I really think this phrase does need to be totally expunged from the lexicon." – Ewan Birney
Taliking to Scientific America

Some things (all things really) need to be remembered more than others.

John Billings says:

Any research to see if the measels have gotten stronger, changed any, etc…
Maybe the immune systems have gotten weaker?
May as check while you're at it.

The Blizzle Family says:

That doctor and many of the doctors like him are full of shit they tell these lights so they can continue to get there bonuses for giving out those vaccines they do cause autism and I hate that the horrible state of California is forcing parents to get these vaccines to these children or they can’t go to school it really pisses me off and maybe we should take all these vaccines and come bind them together and shoot all these doctors up with the vaccines and all these other People that think vaccines are good for children and then when they start getting sick and all fucked up will see what they think about it then

Erick Marquez says:

Mmr is fucking dangerous

H TylerE says:

Mercury can not be fully removed from vaccines, you just have to go to the CDC website to see that.

Cue the Anti Vaxxers who don't know the difference between science and pseudoscience … #ignorantpeople
