+#' Mortality Surveillance Data from the National Center for Health Statistics (deprecated)
+#'
+#' The National Center for Health Statistics (NCHS) collects and disseminates the Nation's
+#' official vital statistics. These statistics are based on data provided to NCHS through
+#' contracts with the vital registration systems operated in the various jurisdictions
+#' legally responsible for the registration of deaths (i.e., death certificates) and other
+#' vital events. These data have previously only been released as annual final data files
+#' 12 months or more after the end of the data year. Recent NCHS efforts to improve the
+#' timeliness of jurisdiction reporting and modernize the national vital statistics
+#' infrastructure have created a system capable of supporting near real-time surveillance.
+#' Capitalizing on these new capabilities, NCHS and CDC’s Influenza Division have
+#' partnered to pilot the use of NCHS mortality surveillance data for Pneumonia and
+#' Influenza (P&I) mortality surveillance.
+#'
+#' NCHS mortality surveillance data are presented by the week the death occurred.
+#' Nationally P&I percentages are released two weeks after the week of death to allow for
+#' collection of enough data to produce a stable P&I percentage at the national level.
+#' Collection of complete data is not expected, and reliable P&I ratios are not expected
+#' at the region and state level within this two week period. State and Region level
+#' counts will be released only after 20% of the expected number of deaths are reported
+#' through the system.

+vital events. These data have previously only been released as annual final data files
+12 months or more after the end of the data year. Recent NCHS efforts to improve the
+timeliness of jurisdiction reporting and modernize the national vital statistics
+infrastructure have created a system capable of supporting near real-time surveillance.
+Capitalizing on these new capabilities, NCHS and CDC’s Influenza Division have
+partnered to pilot the use of NCHS mortality surveillance data for Pneumonia and
+Influenza (P&I) mortality surveillance.
+}
+\details{

+Nationally P&I percentages are released two weeks after the week of death to allow for
+collection of enough data to produce a stable P&I percentage at the national level.
+Collection of complete data is not expected, and reliable P&I ratios are not expected
+at the region and state level within this two week period. State and Region level
+counts will be released only after 20% of the expected number of deaths are reported

+\item{years}{a vector of years to retrieve data for (i.e. \code{2014} for CDC
+flu season 2014-2015). CDC has data for this API going back to 1997.
+Default value (\code{NULL}) means retrieve \strong{all} years. NOTE: if you
+happen to specify a 2-digit season value (i.e. \code{57} == 2017-2018)
+the function is smart enough to retrieve by season ID vs convert that
+to a year.}
