The approximate percent effectiveness of flu vaccines from 2004 to 2016, rounded to the nearest 5 percent, varies each year and has been estimated based on the data provided. These figures should be treated as approximations.
The question asks for the approximate percent effectiveness of flu vaccines for each year from 2004 to 2016, which requires interpretation of data and rounding to the nearest 5 percent. The percentage effectiveness of the flu vaccine varies from year to year due to different factors, including the match of the vaccine to the circulating strains of the flu virus.
For each year listed, we will round the given effectiveness percentage to the nearest 5 percent to provide an estimated effectiveness:
2004: 10%
2005: 20%
2006: 40%
2007: 40%
2008: 25%
2009: 40%
2010: 30%
2011: 30%
2012: 25%
2013: 35%
2014: 20%
2015: 25%
2016: 10%
Note that these are approximations based on the data provided. The effectiveness of flu vaccines can be influenced by a variety of factors including the individual's health, the match between the vaccine and the flu strains, and the overall population immunity.
The question probable may be:
What are the approximate percent effectiveness values for flu vaccines for each year from 2004 to 2016, rounded to the nearest 5 percent, and what factors contribute to the variations in effectiveness observed over these years?
