Background: Mozambique introduced 10-valent pneumococcal conjugate vaccine (PCV10) in 2013 with doses at ages 2, 3, and 4 months and no catch-up or booster dose. We evaluated PCV10 impact on the carriage of vaccine-type (VT), non-VT, and antimicrobial non-susceptible pneumococci 3 years after introduction.
Methods: We conducted cross-sectional carriage surveys among HIV-infected and HIV-uninfected children aged 6 weeks to 59 months: 1 pre-PCV10 (2012-2013 [Baseline]) and 2 post-PCV10 introductions (2014-2015 [Post1] and 2015-2016 [Post2]).
Background: Dried blood spots (DBS) have been proposed as potentially tool for detecting invasive bacterial diseases.
Methods: We evaluated the use of DBS for S. pneumoniae and H.
Background: Invasive pneumococcal disease (IPD) is a significant cause of morbidity and mortality among children worldwide. In April 2013, Mozambique introduced 10-valent PCV (PCV10) into the National Expanded Program on immunization using a three-dose schedule at 2, 3, and 4 months of age. We aimed to evaluate the invasive disease potential of pneumococcal serotypes among children in our region before and after PCV10 introduction.

Mozambique introduced 10-valent pneumococcal conjugate vaccine (PCV10) in April 2013, using a 3-dose schedule without a booster. We evaluated PCV10 impact on pneumococcal carriage and colonization density by HIV status.

Pneumococcal colonization studies are traditionally done among healthy children in the community; however, VT colonization prevalence may differ between these children and those with pneumonia. We assessed overall and VT pneumococcal colonization and factors associated with colonization among children with and without pneumonia after Mozambique introduced 10-valent PCV (PCV10) in 2013.
