Flu season is here again. While most cases are seen in the winter months, influenza starts appearing in October and continues through April. The peak of influenza disease in the Northeast is typically in February, but cases will linger into early spring. It is ideal to get your flu shot early in flu season!
Why should you get the flu vaccine? Influenza, or “the flu”, affects between 5 – 20 percent of our population. It is responsible for 200,000 hospital admissions and 36,000 deaths each year. It is the most common vaccine-preventable illness.
Influenza is a respiratory illness caused by influenza viruses. There are two main types of virus: influenza A and influenza B. Each type includes many different strains, which tend to change each year. This is why flu shots must be given every year.
The 2011-2012 flu vaccine will protect against the three influenza viruses that research indicates will be most common during the season. This includes the H1N1 and H3N2 influenze A viruses, and an influenza B virus.
Influenza is extremely contagious and is easily transmitted through contact with droplets from the nose and throat of an infected person during coughing and sneezing. These viruses may also be spread when a person touches these droplets on another person or an object and then touches their own mouth or nose (or someone else’s mouth or nose) before washing their hands.
If you have ever had “the flu” you know it is no fun. Symptoms may include high fever, body aches, headache, dry cough, sore throat and extreme fatigue. Stomach symptoms like nausea, vomiting, and diarrhea can occur and are much more common in children than in adults.
Although anyone can get the flu, there are some groups that are at high risk for complications. The high risk groups include:
• Adults 50 and older, especially those 65 and older;
• Children 6 months – 18 years;
• People age 6 months and older with chronic medical conditions, including heart disease, pulmonary disorders (including asthma), diabetes, kidney disease, hemoglobinopathies, and compromised immune systems (HIV or immunosuppressive therapy);
• People with certain conditions (such as neuromuscular disorders) that can cause breathing problems
• Pregnant women
• Residents of nursing homes and chronic-care facilities
Other individuals are at high risk of transmitting the flu. These include:
• Health care workers involved in direct patient care;
• Out-of-home caregivers and household contacts of children aged < 6 months.
There are two vaccines available to prevent influenza.
The first is the "flu shot"— an inactivated vaccine containing killed virus.
The flu shot is approved for use in people older than 6 months, including healthy people and people with chronic medical conditions.
The second is the nasal-spray flu vaccine — a vaccine made with live, weakened flu viruses. It is approved for use in healthy people 2-49 years of age who are not pregnant.
There are two common myths associated with flu vaccine.
The first is that the vaccine will give you the flu. It is not possible to get the flu from the flu vaccine. Side effects of the flu shot do include soreness, redness or swelling at the site of the injection, low grade fever and mild body aches. This is not the flu but your body’s response to the vaccine. Side effects of the nasal flu vaccine in children can include runny nose, wheezing, headache, vomiting, muscle aches, and fever. In adults, side effects can include runny nose, headache, sore throat, and cough.
The second myth is that the vaccine does not work. In years when the vaccine and circulating influenza viruses are well matched, the flu vaccine can be expected to reduce laboratory-confirmed influenza by 70 – 90 percent. In years when the viruses are not as well matched it will still lower incidence of disease as well as reduce severity in those who do get influenza. We must remember that not all flu-like illnesses are influenza, and the flu shot can only protect us against influenza viruses.
So is it time for your flu vaccine? Yes, flu vaccine is now routinely recommended for everyone, babies, children, and all adults. It takes about two weeks for your body to make a response to the vaccine, so call your doctor and get your flu shot before peak flu season arrives.
