How to protect your little one from bacteria and viruses
You soothe your newborn baby’s cries, and you revel in their first smile. They need you for everything — and you want to protect them from everything — but how do you safeguard their fragile immune system from sickness and flu?

“It’s important to consider, especially in the early weeks of a baby’s life,” says pediatrician Camille Sabella, MD.
“An infant’s immune system doesn’t mature until they’re about two to three months old,” Dr. Sabella says.
“In those first few months, the immune system — especially cell-mediated immunity — becomes more developed. This is very important in helping a child fight off viruses.”
This means that a 2-week-old baby’s immune system can’t fight viruses or bacteria nearly as well as a 3-month-old’s can.
On the bright side, the mother’s immune system does continue to protect her infant with antibodies that were shared through the placenta immediately after birth. “Those antibodies stay active for the first few weeks of a baby’s life,” Dr. Sabella says.
This offers some protection from bacteria and viruses. Breastfeeding also boosts this early immunity.
There are plenty of ways to help cut down your baby’s risk of sickness.
For starters, know when you absolutely should call a doctor. This includes any of the following signs:
Keep in mind that new babies are vulnerable to viruses. Here are some of the most common to watch out for:

“There are things you can do to protect your baby during the first few months of life,” Dr. Sabella says.
1. Limit outside exposures. You can’t keep your baby in a bubble until they reach the six-month mark. But you can limit contact with other people. And ask visitors to wash their hands before touching the child.
“The first two months of life, we really regard as a sacred time to try to limit exposures as much as possible because babies can get viruses from people who don’t even know they’re contagious yet,” he says.
2. Watch for fever. It’s difficult for doctors to determine whether a virus or bacteria is causing an infant’s illness. So, they err on the side of caution. “Any fever — 100.4 degrees F or higher — will likely land your baby in the hospital for IV antibiotic treatment,” Dr. Sabella says. In some cases, doctors will order a spinal tap to rule out meningitis.
“Our ability to distinguish between a virus and a bacterial infection right up front is limited,” he says. “We often have to do everything and treat it to rule out worst-case scenarios.”
3. Keep up with vaccines. “Keeping your infant up-to-date with vaccines is critical to their health,” Dr. Sabella says, “Especially during the COVID-19 pandemic.”
The whooping cough (pertussis) vaccine is particularly important. The illness is life-threatening for a child under six months of age. “Babies should receive the vaccine first at two months,” he says.
Hib and Prevnar vaccines protect against bloodstream infections and meningitis.
If you’re reading this before having your child, consider getting the flu vaccine. It isn’t given to infants. But vaccination for the mother during pregnancy protects the baby as well.
Being aware, taking common-sense precautions and connecting with a doctor as needed all can help protect your newborn baby. It’s better to be safe than sorry.
