**3.6. Healthcare professionals: booster schedule**

In countries that have implemented pertussis vaccination for adults, vaccination of healthcare workers should be given priority, but there is no evidence that this decreases the acquisition or transmission of the disease but otherwise avoids nosocomial disease transmitted to newborns and young infants. Health professionals in contact with pregnant women, parturients, newborns, and young infants should also be prioritized. New studies are needed to assess the real impact of this measure [16, 44, 62].
