Whooping cough, or pertussis, is resurging across the country, prompting renewed concern from public health officials.This highly contagious respiratory illness poses a important threat, particularly to infants who are too young to be fully vaccinated [[1]]. With its potential for severe complications – and the fact that individuals can spread the infection before showing symptoms – preventative measures like vaccination are critical in protecting the most vulnerable among us [[2]].
Whooping cough, also known as pertussis, is a highly contagious bacterial infection that can be severe, particularly for infants. A key concern is that individuals can be contagious for several days before showing any symptoms, making preventative measures crucial. Vaccination of close contacts, including grandparents, is recommended to protect vulnerable babies.
Whooping Cough Can Last for Weeks

Whooping cough – medically known as pertussis – is far more than a common cold. The cough can persist for weeks, accompanied by severe coughing fits that can even lead to fractured ribs or pneumonia. Individuals are most contagious during the early stages of the illness, often before clear symptoms appear.
Infants are at Highest Risk
Infants under six months old are particularly vulnerable to whooping cough. They can contract the infection through close contact with infected adults, typically via respiratory droplets produced by coughing or sneezing. Often, unknowingly, parents or grandparents are the source of transmission. The risk of serious complications is high for these young children, including breathing cessation, seizures, and even brain damage. Tragically, approximately one percent of infants under six months who contract whooping cough die from its consequences; they often don’t exhibit a typical cough, but rather stop breathing. This underscores the importance of preventative measures to safeguard this vulnerable population.
Protecting the Youngest: Vaccination for Close Contacts
Vaccination is the most effective preventative measure. Because infants cannot be vaccinated until they are two months old, the “cocoon strategy” is recommended to protect them. This involves ensuring that all close contacts – including parents, siblings, caregivers, and grandparents – are up-to-date on their whooping cough vaccinations. According to recommendations from the Standing Committee on Vaccination (STIKO), the last vaccination should have been administered no more than ten years prior. Full protection is typically achieved two weeks after a booster dose.
Vaccination Recommended During Pregnancy
STIKO also recommends that all pregnant women receive a whooping cough vaccination during the third trimester (starting at week 28 of pregnancy), regardless of their previous vaccination history. If preterm labor is anticipated, vaccination should be moved to the second trimester. This allows protective antibodies to be passed to the baby in utero, providing early immunity.
