Tomorrow's Health: Importance Of Childhood Immunizations


Story Updated: Mar 11, 2014

A new study shows the importance of childhood immunizations. Also, infant sleep machines could lead to hearing loss and medical marijuana might be a bad idea for some arthritis patients.

Childhood Immunizations

A new study shows the impact of childhood immunizations. It finds vaccinations prevented 42,000 early deaths, prevented 20 million cases of disease, and saved over $13 billion.

The report, published in the journal Pediatrics, estimates every dollar spent on immunization saves at least $10 down the road.

Infant Sleep Machines

Popular infant sleep machines could contribute to a baby's hearing loss, according to another study in Pediatrics. 

Researchers tested 14 machines and found they exceed the current recommended noise limits for infants.

Experts say that can affect hearing, speech and language development. The study suggests moving noise machines at least six feet from infants.

Marijuana & Arthritis

Medical marijuana might not help those who suffer from rheumatoid arthritis.

While it is sometimes used to treat intense levels of pain, scientists in England and Australia found no positive impact in patients with rheumatoid arthritits.

That could be due to a different mechanism in the type of pain.
