Odds Ratios for carriage of S. pneumoniae serotypes in nasopharyngeal samples by vaccine doses received

Serotype	Dose 1/2 ORa (95 % CI)		Dose 3 OR (95 % CI)
	Aboriginal	Non-Aboriginal	Aboriginal	Non-Aboriginal
7vPCV serotypes	0.90 (0.43, 1.88)	1.93 (1.13, 3.32)	0.19 (0.08, 0.44)	0.83 (0.41, 1.66)
Non-7vPCV serotypes	1.83 (1.04, 3.20)	1.25 (0.57, 2.74)	2.50 (1.17, 5.35)	1.19 (0.65, 2.17)

^aOR odds ratio from logistic regression, adjusting for age and age-squared and accounting for repeated sampling of individuals, with unvaccinated as the reference category. Non-typeable pneumococci were excluded
