An immunization (vaccination) to protect against pertussis ( whooping cough ), a bacterial infection that affects the airways and is characterized by a severe, persistent cough and whooping or crowing sound on inspiration. Pertussis lasts for weeks and can cause coughing spells so severe that infants are unable to breathe, eat, or drink. It can also lead to serious complications such as pneumonia, seizures, and brain damage, and is occasionally fatal.
