As a new parent, you may be wondering how your baby is able to fight off infections and diseases despite their weak immune system. The answer lies in passive immunity, a type of immunity that is passed down from the mother to the baby. In this article, we will discuss how a baby develops passive immunity and the role it plays in protecting them from harm.

What is passive immunity?

Passive immunity is the transfer of pre-formed antibodies from one individual to another. In the case of a baby, passive immunity is acquired from their mother while they are still in the womb or through breast milk after birth. These antibodies provide temporary protection against diseases until the baby’s immune system is strong enough to produce their antibodies.

How does a baby acquire passive immunity?

A baby can acquire passive immunity in two ways:

• In utero: Antibodies can pass through the placenta from the mother to the baby during pregnancy. This ensures that the baby has some level of protection against infections and diseases soon after birth.
• Through breast milk: Breast milk contains antibodies that can help protect the baby from infections and diseases. The antibodies in breast milk are specific to the mother’s immunity and can provide targeted protection to the baby.

What are the benefits of passive immunity for babies?

Passive immunity provides several benefits to babies, including:

• Immediate protection: Passive immunity provides immediate protection to babies against infections and diseases, giving their immune system time to develop.
• Targeted protection: The antibodies passed down from the mother through breast milk are specific to the mother’s immunity, providing targeted protection to the baby.
• Reduced risk of infections: Babies with passive immunity are less likely to contract infections and diseases, which can be severe in infants.
• Reduced hospitalization rates: Passive immunity can reduce the rates of hospitalization in infants due to infections and diseases.

How long does passive immunity last?

Passive immunity is temporary and only lasts for a few months after birth. The antibodies passed down from the mother gradually decrease in the baby’s system and are eventually replaced by their antibodies as their immune system develops.

What happens when passive immunity wears off?

As passive immunity wears off, the baby’s immune system starts producing their antibodies. This process takes time, and during this period, the baby may be susceptible to infections and diseases. It is crucial to ensure that the baby receives all their immunizations to protect them from preventable diseases.

Conclusion

In conclusion, passive immunity is a crucial component of a baby’s immune system. It provides immediate and targeted protection against infections and diseases until the baby’s immune system is strong enough to produce their antibodies. As a parent, it is essential to ensure that your baby receives all their immunizations to protect them from preventable diseases.
