Abstract
Portugal introduced (2+1) conjugate Meningococcal group C vaccine in 2006 with high coverage catch up to 18 years and has given only 1 dose at 1 year since 2012. Among 601 student oropharyngeal swabs, meningococcal carriage rate was 13.3% (A-0%, B-5.3%, C-0.3%, W-0.2%, X-0.2% and Y-1.7%). C and W strains were of potentially disease-causing clonal complexes (cc) but not the hyperinvasive cc11.
