A small but growing number of parents across the U.S. refuse to vaccinate their kids, doubting the efficacy and safety of the vaccines.

The article suggests an intriguing reason for these refusals:

It is the absence, or close to it, of some illnesses in the United States that keep some parents from opting for the shots. Worldwide, 242,000 children a year die from measles, but it used to be near one million. The deaths have dropped because of vaccination, a 68 percent decrease from 2000 to 2006.

“The very success of immunizations has turned out to be an Achilles’ heel,” said Dr. Mark Sawyer, a pediatrician and infectious disease specialist at Rady Children’s Hospital in San Diego. “Most of these parents have never seen measles, and don’t realize it could be a bad disease so they turn their concerns to unfounded risks. They do not perceive risk of the disease but perceive risk of the vaccine.”

Most of these concerns, however, are unfounded: the safety risk of most vaccines are negligible. And failing to vaccinate not only puts the non-vaccinated child at risk, but also his or her playmates. Even effective vaccines do not work 100% of the time, so a vaccinated child is not necessarily protected from his or her non-vaccinated friends.

Babies under the age of one are especially susceptible to meningitis. They have the highest rates of infection, but the currently-existing vaccine cannot be used on them. It is restricted to children over two.

However, an experimental vaccine called Menveo may be effective in these infants. Here is what experts have to say about it:

The vaccine was about 94% effective when given in four doses, one at 2 months, 3 months, 4 months and 12 months — a dosing schedule that fits into standard vaccination programs in the U.K., says study author Matthew Snape, a pediatrician at the University of Oxford.

When given in three doses, one each at 2 months, 4 months and 12 months — the standard pattern for shots in the USA — the vaccine was 86% to 100% effective, providing more protection against some strains of the bacteria than others, Snape says.

If approved, a meningococcal vaccine could prevent half of the roughly 300 cases of meningococcal meningitis in babies under 2, says Amanda Cohn, a pediatrician at the Centers for Disease Control and Prevention.

Thirteen childhood diseases for which we have vaccines are causing fewer deaths than ever, according to a new study done by the Centers for Disease Control and Prevention (CDC).

Deaths and hospitalizations from smallpox, diphtheria and polio have gone down one hundred percent since vaccines against them were approved. Deaths and hospitalizations from nine of the diseases have gone down ninety percent, and only in only four diseases (all of which have vaccines that were approved only recently and thus have had less time to take effect in the population) did they go down less than ninety percent. Those four diseases were hepatitis A and B, varicella and invasive pneumococcal diseases.

This is a striking demonstration of the value of vaccinating children--a practice that is sometimes controversial, as many parents oppose it either for religious reasons or because of skepticism about its efficacy. Hopefully studies like these will address some of that skepticism and promote the use of vaccines in preventing deadly diseases.
