The Centers for Disease Control and Prevention (CDC) have recommended that people get a flu shot. However, vaccine producers are saying that the ones who already got the shot may not need to get it again.

This reason behind this is that the vaccine this year is the same flu vaccine that was out last year. This due to the fact that the exact flu is circulating.

The major makers of the flu vaccine stated that there will be more than enough of flu vaccines to go around this year.

In total, it is predicted that there will be around 170 million vaccines to go around to the U.S. public in 2011 which is higher number than last year.

This number is at least 6 million more than the most ever produced.

Americans are getting flu shots in ever increasing numbers; over the last ten months over 40 percent of the population did get vaccinated, compared to 30 percent in past years.
