Cobertura de vacunación contra la influenza, niños de entre 6 meses y 17 años, Estados Unidos

Child Flu Vaccination Coverage

Weekly Influenza vaccination coverage and parental intent for vaccination among children is calculated using data from the Encuesta Nacional de Inmunización contra la Influenza (NIS-Flu).  NIS–Flu is a national random-digit-dialed cellular telephone survey of households with children ages 6 months–17 years conducted during October-June. The respondent to a NIS–Flu survey is a parent or guardian who said they were knowledgeable about the child's vaccination history.  All estimates are based upon parental report of receipt of vaccination and month of that vaccination.

^{Note: Confidence Intervals (CI) describe the level of uncertainty around an estimate because a sample was taken. 95 % CIs represent the range of values that would result if the data collection had been repeated many times. For a 95 % confidence interval, if the sampling method is repeated many times, the true value would fall within this interval at least 95 % of the time. Los intervalos de confianza más amplios reflejan un mayor error aleatorio en las estimaciones resultantes del muestreo de encuestas.}

^{Estimates from the NIS may differ from estimates based on other data sources, and in addition to random error associated with taking a sample, are subject to errors resulting from incomplete sample frame (exclusion of households without cell phones), selection bias (survey respondents may be more likely to be vaccinated than non-respondents), and errors in self or parental reported vaccination status. Las estimaciones se ponderan según las características sociodemográficas seleccionadas de la población de los EE. UU. para reducir el posible sesgo por un marco de muestra incompleto y el sesgo de selección.}

^{*National estimates include 50 states and Washington D.C. The Office of Intergovernmental and External Affairs hosts 10 Regional Offices that directly serve state and local organizations; information about Regions and which states are included in each region is se encuentran disponibles.}

^{†Las fechas de final de semana de las temporadas anteriores coinciden con las fechas de final de semana de la temporada actual. Sample size is insufficient to provide estimates by demographics within jurisdictions.}

^{‡Cumulative vaccination coverage estimates are suppressed when the cumulative sample size is <30 or current week sample size is <5. Vaccination intent estimates for a given week are suppressed when the sample size for that week is <30.}

^{§Estimates for parental vaccination intent are based on interviews conducted during that week and are adjusted to the cumulative vaccination coverage estimate for that week.}

^{±La interpretación de la diferencia entre la temporada actual y la temporada anterior se basa en el 95 % del intervalo de confianza (CI) de la diferencia. La interpretación es "Similar a la última temporada" si el CI del 95 % de la diferencia es cero; "Inferior a la última temporada" si el CI del 95 % de la diferencia es inferior a cero y "Superior a la última temporada" si el CI del 95 % de la diferencia es superior a cero.}
