Duration of first pneumococcal carriage episode, stratified by NPS culture/serotyping method.

<p>100 infants were included in each group.</p

<p>100 infants were included in each group; each serotype considered independently.</p>a<p>Acquisition rate per day.</p>b<p>Non-typeable pneumococcal colonisation excluded.</p

Infant carriage pneumococcal serotype distribution, by latex sweep serotyping.

<p>Results of culture of 8,736 swabs from 364 infants. The bars indicate the number of isolates of each serotype and the dashed lines indicate the cumulative frequency (cumulative frequency of 67% is indicated by the vertical arrows). Dark grey bars highlight PCV13 serotypes.</p
