This is a reminder that a travel medical consultation is an opportunity to check pertussis vaccination status. Swiss recommendations: After basic immunization against whooping cough, booster vaccinations are recommended for adolescents (11-15 years) and adults (25-29 years). A booster vaccination is also recommended for every pregnancy. In addition, adolescents and adults of all ages should be vaccinated against whooping cough if they have regular occupational or family contact with infants under 6 months of age and it has been 10 years or more since their last vaccination against whooping cough.
