Is there thimerosal in the H1N1 vaccine?

Thursday, November 5th, 2009

vaccine1Some H1N1 flu vaccines have a preservative called thimerosal. Although some people have suggested a link between thimerosal and autism,  medical experts from the Institutes of Medicine (IOM) have thoroughly researched the issue and concluded that thimerosal-containing vaccines are NOT associated with autism. However, if you’re still concerned, a thimerosal-free version of the H1N1 vaccine is available.

The 2009 H1N1 influenza vaccines that FDA is licensing (approving) will be manufactured in several formulations. Some will come in multi-dose vials and will contain thimerosal as a preservative. Multi-dose vials of seasonal influenza vaccine also contain thimerosal to prevent potential contamination after the vial is opened.

Some vaccine manufacturers will be producing 2009 H1N1 influenza vaccine in single-dose units, which will not require the use of thimerosal as a preservative. In addition, the live-attenuated version of the vaccine, which is administered intranasally (through the nose), is produced in single-units and will not contain thimerosal.  The nasal spray version, however, is not recommended for pregnant women.

U.S. federal court: No link between vaccines and autism

Friday, February 13th, 2009

gavel-smYesterday, a U.S. federal court dismissed cases from parents who claimed that vaccinations caused their children’s autism. According to NBC Nightly News, ”the parents failed to show that vaccinations played any role at all in causing autism.”

While some families still fear that there may be a connection between autism and vaccines, a large body of well-done research has found no link. The U.S. Centers for Disease Control and Prevention, the American Academy of Pediatrics and the March of Dimes all recommend that children be vaccinated.

While expressing concern for children with autism and their parents, the court said the research used to support the claims was severely inadequate. In the court’s view, the medical experts testifying for the parents were poorly qualified and lacked sufficient experience. In making its decision, the court reviewed over 5,000 pages of expert testimony and 939 medical articles.

The U.S. Department of Health and Human Services (DHHS) and other organizations continue to support research to better understand the causes of autism. In a statement, DHHS said that it hoped the court’s decision “will help reassure parents that vaccines do not cause autism.”

Autism and immunizations: No connection

Friday, December 12th, 2008

For many years now, some families have been worried about a possible connection between autism and childhood immunizations. One small study many years ago raised the question. But since then, better-designed and more extensive research has found no connection between autism and immunizations.

This is how science works. One study leads to another and then another, until we have a better understanding of what’s going on.

Despite the newer studies, the debate continues. Meanwhile, if children aren’t immunized, they and their communities face the risk of very serious, even life-threatening diseases like diphtheria and measles.

The actress and mother Amanda Peet is speaking out, urging parents to immunize their kids. She’s joined forces with Dr. Paul Offit, chief of infectious diseases at the Children’s Hospital of Philadelphia.

On December 11, Ms. Peet and Dr. Offit spoke to National Public Radio. Give a listen. To learn more about autism and what scientists know about the causes, read the March of Dimes fact sheet.

The U.S. Centers for Disease Control and Prevention, the American Academy of Pediatrics and the March of Dimes recommend that children be immunized.

New study: No connection between MMR vaccine and autism

Thursday, September 4th, 2008

I don’t like to see children cry when they get their vaccinations. But the truth is, those shots can be life-saving.

A new study provides more evidence that there is no connection between the measles-mumps-rubella (MMR) vaccine and an increased risk of autism. Researchers from Columbia University, Harvard University and other institutions published their findings in the online journal PLoS ONE.

In 2004, the Institute of Medicine reviewed all medical research about a possible link between autism, the MMR vaccine, and vaccines containing a preservative called thimerosol. The institute concluded that there was no connection.

But some people are still concerned and won’t let their children be vaccinated. This latest study should help reassure both parents and health care providers. For the safety of your children, get them vaccinated.
