Detailed explanation-1: -A newborn baby acquires passive immunity from its mother through the placenta. People can also get passive immunity through antibody-containing blood products such as immune globulin, which may be given when immediate protection from a specific disease is needed.
Detailed explanation-2: -For example, passive immunity occurs when a baby receives a mother’s antibodies through the placenta or breast milk. It can also occur when a person receives an injection of antibodies to protect against the effects of a toxin such as snake venom.
Detailed explanation-3: -However, several studies support the role of passive immunity against mucosal pathogens (see Table 8.3), including examples such as influenza (respiratory virus), Haemophilus influenzae (respiratory bacterium), rotavirus (enteric virus), and Escherichia coli (enteric bacterium).
Detailed explanation-4: -Colostrum, which has antibodies (IgA) to protect the infant provides passive immunity to a new born baby [1].
