The protection a toddler gets begins even earlier than birth. Even when pregnant, a mom does not only supply her child meals and shelter; she also provides much-needed immunity, which is the body's protection mechanism.

Vaccines taken in the path of pregnancy help the mother stay wholesome and receive the infant prepared to guard against some infections all through the primary few months of existence when his or her immune device is susceptible. That is critical within the first few weeks after the delivery, which is when toddlers are extraordinarily at risk of dangerous infections.

How Maternal Vaccination Works
Antibodies are unique proteins made by the body in response to vaccines. Whilst waiting for mothers to be vaccinated, her frame produces antibodies specific to the vaccine. Particularly, IgG (immunoglobulin G) antibodies are vital at some stage in pregnancy. These IgG antibodies are able to cross the placenta, which is the tissue that hyperlinks the mother and fetus, and enter the fetus’s bloodstream gadget. This placental switch technique is enhanced beautifully in addition at some stage in the third trimester (after 28 weeks of being pregnant). By the time the baby is born, they have already gotten a supply of protecting antibodies, thanks to the mom’s vaccination. This is called passive immunity due to the fact the baby gets it passively, without needing to produce antibodies on their own. These antibodies live within the child’s frame for the primary few months of life, giving them an early defense against illnesses.
Why Newborns Need Extra Protection
After birth, toddlers no longer have a fully evolved immune system. Their frame is still getting to know how to respond to infections and bring its personal antibodies. Vaccines given without delay to toddlers commonly begin after 6 weeks of age. Till then, they're exceedingly vulnerable to infections like whooping cough (pertussis), influenza (flu), and tetanus, which may be very critical or even life-threatening in newborns. Maternal vaccination fills this hole by means of offering brief protection all through the early months; that's often known as the "immunity gap."

Breastfeeding keeps the protection.
The protection doesn’t forestall at birth. Moms who are vaccinated pass even more antibodies to their toddlers via breast milk. These antibodies, specifically IgA (immunoglobulin A), help protect the baby’s lungs and intestines from infections. This is especially essential for viruses like the flu and COVID-19, which attack the respiratory system. So, breastfeeding acts like an herbal booster shot for the baby within the first few months.
