Expert Answer
Infants are particularly vulnerable to infectious diseases. Therefore, it is important to protect them through immunisation. Immunization helps to prevent the spread of diseases and protects infants and toddlers against dangerous complications.
Artificially acquired active immunity occurs through the injection of the causative agent into the person’s system through immunization. The causative agent is diluted to reduce its virulence so that the recipient will form antibodies without any effect on the body.
