Pertussis Vaccination in Damansara Jaya — Whooping Cough Protection From 2 Months

What Is Pertussis — and Why Is It Especially Dangerous for Infants?

Pertussis — commonly called whooping cough — is a highly contagious bacterial respiratory infection caused by Bordetella pertussis. It spreads through respiratory droplets and is one of the most transmissible infectious diseases known: a single unprotected individual in a household with pertussis will typically infect 12–17 others without vaccination providing a barrier.

The disease gets its name from the characteristic high-pitched "whoop" sound that follows violent coughing fits as the patient gasps for air. In older children and adults, pertussis is miserable but rarely fatal — the cough can last 6–10 weeks and is intensely disruptive to sleep and daily life. In infants under 6 months, however, the disease is a medical emergency. Young infants often cannot generate the classic whooping sound — instead they experience prolonged apnoeic episodes (pauses in breathing), cyanosis (turning blue), and can die from respiratory failure.

Vaccination through the childhood DTaP series is the most effective protection. Pregnant women are also recommended to receive a Tdap booster in the third trimester — the antibodies pass to the newborn before they are old enough to be vaccinated themselves.
