Although it is hard to predict an influenza season, the authors noted that when A (H3N2) viruses was the dominant influenza strain in past seasons, hospitalizations and deaths were more common and the effectiveness of the vaccine was lower. There were 157 cases this same time a year ago.
"Some protection is better than no protection", Kern County Public Health Services Department spokeswoman Michelle Corson said, stressing the importance of the vaccination.
That's just one reason scientists have been trying to come up with a universal flu vaccine for years now. "It mutates as it goes from person to person, that's why it's so hard to predict what season we'll have".
Most flu seasons don't really get going until around Christmas. This year, there have been no severe cases or related deaths, Corson said.
Doctors say what happens in the US with flu season tends to mirror what happened in the southern hemisphere.
The Centers for Disease Control and Prevention advises people to get a flu vaccine by the end of October, but early December is still ahead of the typical flu season peak, which is usually between December and March.
And finally, if you can, stay at home if you're sick.
The four most deadly flu seasons of the last 10 years - in the winters of 2003-2004, 2007-2008, 2012-2013, and 2014-15 - were H3N2 seasons, each with a particular version of that flu type. Doctors still urge everyone older than six months to get the vaccine, because it takes two weeks to build up immunity.
Dr John Rodriguez, Public Health Screening and Immunisation lead for Kent and Medway said: "It is important we protect young children from the flu virus and get them vaccinated now". This year, some experts claim the flu shot may only be 10 percent effective.
"A common myth is that the flu shot can give you the flu", said Swift. This report also includes granular analysis of the market share, geographic regions and revenue forecasts and of the North America Flu Vaccine market. When your immune system kicks into gear making antibodies, your body's natural response can involve fatigue, soreness and even mild fever. "Most people have no reaction at all, other than mild soreness in the arm where the shot was administered".
So to verify, it is still unknown how effective the vaccine will be in the US, but it will help.
