    US influenza vax coverageincreasing, but still "suboptimal"Influenza virus vaccine coverage in infants at inner

    city New York practices has shown a steady recentincrease from 200020005, although coverage remains"suboptimal", according to a study by US researchers.

    They conducted a retrospective review of the fiveinfluenza seasons between 2000 and 2005 to evaluatethe influenza virus vaccine coverage among infants aged623 months (n = 7063) at an inner city practice centrenetwork in New York city. They estimated coveragelevels for one dose (partial coverage) and two doses (fullcoverage); missed vaccination opportunities were alsoassessed.

    Over the 5-year period, coverage levels increased forany dose from 3.2% (95% CI 2.2%, 4.1%) to 41.8%(39.2%, 44.3%). The proportion of fully immunisedchildren rose from 1.6% (1.0%, 2.3%) to 23.7% (21.5%,25.9%), with the proportion of partially vaccinatedchildren increasing from 1.5% (0.9%, 2.2%) to 18.1%(16.0%, 20.1%). However, there were missedopportunities for vaccination in 82.2% of visits (95% CI,81.5%, 83.0%). Notably, 89.2% (88.6%, 89.8%) of thevisits during which a first dose could have beenadministered resulted in missed opportunities. Of visitseligible for a second dose, the proportion of missedopportunities was lower, at 38.4% (35.9%, 40.8%). Theresearchers note that such "low coverage levels arestriking when compared with the high levels. . . seen forother childhood vaccines in the United States".Verani JR, et al.
