Why is passive immunity only temporary?

The recipient will only temporarily benefit from passive immunity for as long as the antibodies persist in their circulation. This type of immunity is short acting, and is typically seen in cases where a patient needs immediate protection from a foreign body and cannot form antibodies quickly enough independently.

How long after birth does immune system return to normal?

Return to normal cellular immune function may take 3 to 4 months in the postpartum. Some aspects of early immunology (hsCRP and IL-6) probably reflect the latter stage of pregnancy, the stress of birth and the inflammation associated with involution.
