In our sample, postexposure prophylaxis with oseltamivir, 75 mg once daily for 7 days, protected close contacts of influenza-infected persons against influenza illness, prevented outbreaks within households, and was well tolerated.

The overall proportion of S. pneumoniae isolates and vaccine serotypes in AOM were significantly reduced by community-wide use of PCV7 vaccine in our practice. The proportion of Gram-negative bacteria became 2-fold more frequent than S. pneumoniae in AOM in PCV7-vaccinated young children where PCV7 uptake was community-wide and supply was adequate.

Zanamivir was effective in shortening the duration and severity of influenza symptoms and was well-tolerated among children 5 to 12 years of age.

In the Phase III PATRICIA study (NCT00122681), the human papillomavirus (HPV)‐16/18 AS04‐adjuvanted vaccine (Cervarix®, GlaxoSmithKline Biologicals) was highly efficacious against HPV‐16/18 infections and precancerous lesions in women HPV‐16/18 deoxyribose nucleic acid (DNA) negative and seronegative at baseline. We present further data on vaccine efficacy (VE) against HPV‐16/18 in the total vaccinated cohort including women who may have been exposed to HPV‐16/18 infection before vaccination. In women with no evidence of current or previous HPV‐16/18 infection (DNA negative and seronegative), VE was 90.3% (96.1% confidence interval: 87.3–92.6) against 6‐month persistent infection (PI), 91.9% (84.6–96.2) against cervical intraepithelial neoplasia (CIN)1+ and 94.6% (86.3–98.4) against CIN2+ [97.7% (91.1–99.8) when using the HPV type assignment algorithm (TAA)]. In women HPV‐16/18 DNA negative but with serological evidence of previous HPV‐16/18 infection (seropositive), VE was 72.3% (53.0–84.5) against 6‐month PI, 67.2% (10.9–89.9) against CIN1+, and 68.8% (−28.3–95.0) against CIN2+ [88.5% (10.8–99.8) when using TAA]. In women with no evidence of current HPV‐16/18 infection (DNA negative), regardless of their baseline HPV‐16/18 serological status, VE was 88.7% (85.7–91.1) against 6‐month PI, 89.1% (81.6–94.0) against CIN1+ and 92.4% (84.0–97.0) against CIN2+ [97.0% (90.6–99.5) when using TAA]. In women who were DNA positive for one vaccine type, the vaccine was efficacious against the other vaccine type. The vaccine did not impact the outcome of HPV‐16/18 infections present at the time of vaccination. Vaccination was generally well tolerated regardless of the woman's HPV‐16/18 DNA or serological status at entry.

We evaluated the efficacy of the human papillomavirus (HPV)−16/18 AS04‐adjuvanted vaccine in preventing HPV‐related disease after surgery for cervical lesions in a post‐hoc analysis of the PApilloma TRIal against Cancer In young Adults (PATRICIA; NCT00122681). Healthy women aged 15–25 years were randomized (1:1) to receive vaccine or control at months 0, 1 and 6 and followed for 4 years. Women were enrolled regardless of their baseline HPV DNA status, HPV‐16/18 serostatus, or cytology, but excluded if they had previous or planned colposcopy. The primary and secondary endpoints of PATRICIA have been reported previously; the present post‐hoc analysis evaluated efficacy in a subset of women who underwent an excisional procedure for cervical lesions after vaccination. The main outcome was the incidence of subsequent HPV‐related cervical intraepithelial neoplasia grade 2 or greater (CIN2+) 60 days or more post‐surgery. Other outcomes included the incidence of HPV‐related CIN1+, and vulvar or vaginal intraepithelial neoplasia (VIN/VaIN) 60 days or more post‐surgery. Of the total vaccinated cohort of 18,644 women (vaccine = 9,319; control = 9,325), 454 (vaccine = 190, control = 264) underwent an excisional procedure during the trial. Efficacy 60 days or more post‐surgery for a first lesion, irrespective of HPV DNA results, was 88.2% (95% CI: 14.8, 99.7) against CIN2+ and 42.6% (−21.1, 74.1) against CIN1+. No VIN was reported and one woman in each group had VaIN2+ 60 days or more post‐surgery. Women who undergo surgical therapy for cervical lesions after vaccination with the HPV‐16/18 vaccine may continue to benefit from vaccination, with a reduced risk of developing subsequent CIN2+.
