In response to an increase in pertussis cases beginning in 2010, Brazil introduced dTpa vaccine into the national immunization schedule for pregnant women in 2013. In the pre-maternal vaccination period (2011–2013), the average annual incidence of pertussis hospitalizations in children under 1 year old was 98.3/100,000 and in the post-maternal vaccination period (2015–2017) the average was 65.9/100,000, a decline of 32.9%.
