By: Anna TullyThe National Center for Health Statistics (NCHS) has released its latest update of the U.S. flu vaccine.

The report was released Friday.

It was based on data from the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH).

The CDC said the number of flu shots is increasing at a steady rate, but the rate of the flu shot in this country is declining.

The new data show that, on average, Americans have only been getting about three doses of the influenza vaccine for about four years.

The rate of decline has slowed dramatically over the last few years, and in 2016 it dropped to just 0.2 percent, according to the CDC.

That’s compared to about 1.5 percent in 2009, and it is now about 0.9 percent.

The number of Americans who are receiving their flu shot has dropped by nearly half, to about 14.7 million in 2020, and by more than three million in 2021.

This is a rate of drop that has not been seen since at least 2000.
