As any parent knows, infants are prone to getting respiratory infections. But a new study shows that the infant immune system is stronger than most people think and beats adults at fighting off new pathogens.
At what age is a baby’s immune system fully developed?
“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.”
Are babies born with strong immune systems?
A baby’s immune system is not fully developed when they are born. It gets stronger as the baby gets older. The immune system works throughout our lives fighting germs that can cause disease. A mother’s antibodies are shared with their baby through the placenta during the third trimester (last 3 months) of pregnancy.
Do infants have weak immune systems?
“Newborns are highly susceptible to illnesses,” she says. “They don’t have much of an immune system of their own, so even pre-pandemic, we advised people to be very careful to germ exposure with newborns, understanding that they develop more robust immune systems over time.”
How long is a newborn immune?
The exact amount of protection that a baby receives from its mother depends on the antibodies that the mother has in her immune system. Research indicates that a baby’s passive immunity lasts for around six months.
Do newborns get sick easily?
First, infants do not have fully developed immune systems, so they are more susceptible to infectious illnesses. Also, when a newborn gets an infection, the illness is often more serious than when an adult or older child gets the same infection.

Recent studies have shown that women have a better immune system against infections than men. This is due to the genetic structural difference. This genetic structure is known as microRNAs.
How do you check a child’s immune system?
Blood tests.
Blood tests can determine if you have typical levels of infection-fighting proteins (immunoglobulins) in your blood and measure the levels of blood cells and immune system cells. Having numbers of certain cells in your blood that are outside of the standard range can indicate an immune system defect.

Do breastfed babies have better immune systems as adults?
Breastfeeding Builds Your Baby’s Immune System
The mother’s body will then make antibodies to that particular germ and transfer them back to the baby at the next feeding. Studies have also shown that babies who are breastfed exclusively have better functioning immune systems in the long-term as well.
Is breast milk better than formula?
