Vaccinating pregnant women protects newborns from whooping cough

A Tdap vaccine during pregnancy led to fewer newborns getting whooping cough in the two months after birth, a large study found.

When I was pregnant, my pronoun shifted automatically. My “I” turned into “we,” as in, “What are we going to eat for dinner?” and, “Should we sit in that hot tub?” I thought about that shift to the majestic plural as we got our Tdap shot in our third trimester.

The Tdap vaccine protects against tetanus, diphtheria and pertussis, or whooping cough. Doctors recommend that women receive a dose with each pregnancy because the diseases can be particularly dangerous for young babies. But good, hard evidence for the benefits of vaccinating women while pregnant instead of shortly after giving birth has been lacking. A new study of nearly 150,000 newborns fills that gap for whooping cough.

Researchers at the Kaiser Permanente Vaccine Study Center in Oakland, Calif., studied the medical records of mothers who gave birth to babies between 2010 and 2015. Overall, about 46 percent of the mothers received a Tdap vaccine at least 8 days before giving birth.

Seventeen of the 150,000 babies got whooping cough by the time…

Furry Friends Could Help Prevent Allergies and Obesity in Babies

Two of life’s great joys—dogs and babies—might be even better together. A study published in the journal Microbiome found higher levels of allergy-preventing bacteria in babies who lived with furry pets like dogs and cats.

The relationship between our environments, immune systems, and gut microbes is a tangled one. Studies have found that “dirty behaviors” like thumb-sucking and nail-biting might actually help protect kids against autoimmune conditions, as can living on a farm. So it’s not too much of a stretch to think that our four-legged companions might have a similarly beneficial effect.

To explore the idea further, researchers at the University of Alberta pulled data from the Canadian Healthy Infant Longitudinal Development (CHILD) study, which followed the lives…

Language heard, but never spoken, by young babies bestows a hidden benefit

Babies who heard Korean spoken in their first six months of life were better able to pick up the language later as adults, a study finds. The results show how early language exposure patterns the brain in ways that may not be revealed for decades, if ever.

The way babies learn to speak is nothing short of breathtaking. Their brains are learning the differences between sounds, rehearsing mouth movements and mastering vocabulary by putting words into meaningful context. It’s a lot to fit in between naps and diaper changes.

A recent study shows just how durable this early language learning is. Dutch-speaking adults who were adopted from South Korea as preverbal babies held on to latent Korean language skills, researchers report online January 18 in Royal Society Open Science. In the first months of their lives, these people had already laid down the foundation for speaking Korean — a foundation that persisted for decades undetected, only revealing itself later in careful laboratory tests.

Researchers tested how well people could learn to identify and speak tricky Korean sounds. “For Korean listeners, these sounds are easy to distinguish, but for second-language…
