With schools fully reopened, health authorities warn that missed vaccinations are leaving children vulnerable to preventable diseases such as whooping cough, diphtheria, and tetanus. Routine vaccinations remain one of the most effective ways to protect children from serious illnesses.

The national institute for communicable diseases (NICD) has reported an increase in pertussis, commonly known as whooping cough, since the start of 2026. A total of 161 confirmed cases were recorded between 1 January and 22 February, signalling ongoing transmission and the need for strengthened public health measures.

“Routine immunisations help protect against serious illness,” said Sanofi South Africa medical manager Shaakira Abrahams. “Keeping immunisations up to date helps safeguard your child, their classmates and your community.”

“Visit your nearest primary healthcare clinic for help. Some schools also offer immunisation days.”

Health experts caution that the consequences of missed immunisations can be severe. Diphtheria can cause breathing difficulties and damage to the heart and nerves.

Tetanus contracted through cuts or wounds can lead to painful muscle stiffness and can be fatal. Whooping cough, meanwhile, can trigger prolonged coughing fits that make breathing difficult, particularly for babies and young children.

Last year, South Africa recorded 614 confirmed cases of whooping cough through the national surveillance system, according to the NICD.

More than half of these infections occurred in children under the age of five, while infants younger than six months accounted for nearly a third of cases, underscoring the vulnerability of young children and the importance of maternal vaccination during pregnancy.

Children should receive routine whooping cough vaccinations at six, ten and 14 weeks after birth, followed by another dose at 18 months. Since 2024, additional booster doses at six and 12 years of age have been introduced in the public health sector to extend protection beyond early childhood, said the NICD.

Parents are encouraged to check their child’s Road-to-Health booklet or clinic card to confirm vaccinations are current. If records are lost, replacement cards can be issued at primary healthcare clinics, where nurses can also administer missed doses.

Parents and caregivers are advised to seek medical attention promptly if children develop symptoms associated with whooping cough.
