In Slovenia, primary acellular pertussis vaccines (ACVs) containing pertactin (PRN) were mostly used during 1999-2016; ACVs without PRN were introduced in 2017. Among 123 Bordetella pertussis strains collected during 2002-2020, a total of 48 were PRN-deficient; 44 were collected after 2017. Changes to ACVs could increase PRN-deficient B. pertussis and infections.
