Flu shots are available: Should you get your flu vaccine now?
Healthbeat Flu Season
People 65 years and older are at greater risk of serious complications from the flu than young,
healthy adults. Most years, about 90 percent of seasonal flu-related deaths and 50 to 60 percent of flu-related occur in people 65 years and older.

You've likely seen signs at local drug stores and grocery pharmacies advertising "Flu shots now available." How soon should we get flu shots?
The&&says early fall is the ideal time for a flu shot because it's impossible to predict when flu will start, and it takes about two weeks for flu shot protection to kick in. Flu activity can begin as early as October. So the CDC recommends that everyone 6 months and old get a flu shot by October.&
But, they say, later isn't too late. Flu season typically peaks in January or February. The most important thing is to get a flu shot.
If we get a flu shot now, will we still be protected come February?
Most healthy people with regular immune systems who get the shot in early fall will remain protected throughout the flu season, the CDC says.
Flu shots are already available at doctor's offices, drugstores, grocery store pharmacies, health clinics and other locations.

The flu vaccine is covered by insurance and Medicare. Drugstore vaccination programs tend to charge about $30 for a standard trivalent shot and other types are slightly more expensive.
Those quadrivalent vaccines will guard against four strains of flu rather than the usual three. Children tend to catch the fourth added strain more often than adults. There are more potent vaccines available for those 65 and older, since that is the group with the highest risk. There are also egg-free shots and cell culture shots.
CDC's only flu vaccine recommendation this year is for the quadrivalent nasal spray vaccine for healthy children 2 through 8 years old who do not have a medical condition that predisposes them to influenza complications. But the CDC says if the nasal spray is not available, don't wait.
Which type of flu shot?
&There are a number of flu vaccine options for the
flu season:
Trivalent flu vaccine protects against two influenza A viruses (an H1N1 and an H3N2) and an influenza B virus. These trivalent flu vaccines are available: & & &&
Standard dose trivalent shots (IIV3) that are manufactured using virus grown in eggs. These are approved for people ages 6 months and older. There are different brands of standard dose trivalent shot, and each is approved for different ages.
A standard dose intradermal trivalent shot, which is injected into the skin instead of the muscle and uses a much smaller needle than the regular flu shot. It is approved for people 18 through 64.
A high-dose trivalent shot approved for people 65 and older.
A standard dose trivalent shot containing virus grown in cell culture, which is approved for people 18 and older.
A standard dose trivalent shot that is egg-free, approved for people 18 through 49.
The quadrivalent flu vaccine protects against two influenza A viruses and two influenza B viruses. These quadrivalent flu vaccines are available:
A standard dose quadrivalent shot.
A standard dose quadrivalent nasal spray, approved for people 2 through 49 and recommended for healthy children 2 to 8.
