Elizabeth Maslow, MD, has one message for parents considering not vaccinating their children against measles:

鈥淭here is no downside to vaccinating your children,鈥� says Dr. Maslow, an infectious disease specialist with 网曝门事件 Health Glendale. 鈥淵ou鈥檙e helping your children and only doing good by getting them vaccinated.鈥�

Measles was considered eradicated from the United States in 2000 thanks to a strong effort to vaccinate every child possible. But that success is in danger of unraveling due to an anti-vaccination movement based not on science, but on a lie, Dr. Maslow says.

The facts about measles

鈥淢easles is a virus transmitted from one person to another by droplets,鈥� Dr. Maslow says. 鈥淪o if I sneeze, a particle flies into the air, where it can linger for two hours. I can sneeze in a cab, get out of the cab and someone who gets in the cab an hour later can catch my measles.鈥�

Measles is so contagious that if one person in a room has the disease, 90 percent of the other people in the room will get it too. That is, if they are unvaccinated.

Measles starts out like a cold鈥攆ever, runny nose, red eyes and a cough. Several days later, a rash spreads all over the body.

Measles generally goes away over time. But it can cause complications, Dr. Maslow notes. These include ear infections, which can sometimes lead to permanent hearing loss, and a brain infection called encephalitis.

Measles also can damage your immune system, leaving you vulnerable to other infections.

Before measles was eliminated, about 400 to 500 people died from it each year. About 1,000 people would develop measles-related encephalitis. That鈥檚 why eliminating measles from the U.S. was such a big victory.

The lie behind the anti-vaccination movement

British medical journal The Lancet published a study in 1998 that suggested that the measles-mumps-rubella (MMR) vaccine was linked to autism. The study only included 12 children, and it was summarily criticized for its poor science. It later was retracted. In addition, questions about the researcher鈥檚 ties to pharmaceutical interests led him to lose his license.

Still, parents desperate to find a cause for their child鈥檚 autism used the study as a rallying cry, Dr. Maslow says.

鈥淏ut there鈥檚 not a single ounce of professional data that supports that retracted study,鈥� she adds.

Measles still doesn鈥檛 occur naturally in this country; It鈥檚 brought in by infected travelers from abroad. But it wouldn鈥檛 be able to take a toehold if everyone was vaccinated.

鈥淚 want them to see that they鈥檝e been misled by an article which has since been retracted,鈥� she says. 鈥淭here鈥檚 not a single chance of getting autism from a vaccine, let alone the MMR vaccine.鈥�

If you think you鈥檝e been exposed to measles, call your doctor as soon as you can鈥攅specially if you鈥檙e pregnant or have a compromised immune system. If you鈥檙e not sure you were vaccinated as a child, let your doctor know. A blood test can determine if you need to be vaccinated.
