Since winter is approaching soon and it is the time for sniffles and sneezing, what do you think about getting a FLU SHOT as an ounce of prevention?
— Achoo, cough, cough
Dear Achoo, cough, cough,
To get the shot or not, that is the question… The flu season typically starts in October, with the peak months being January and February. You can get the flu vaccine anytime during the flu season. For most people the benefits of getting a flu shot far outweigh the concerns. Plus, you can't get the flu from the flu shot!
There are two types of flu vaccines: the injection and the nasal spray. Injectable flu vaccines usually contain killed strains of types A and B flu virus, and help your body to provide immunity to these two common strains of the flu. The nasal spray vaccine contains a live, but weakened version of the same strains. Several clinical studies have shown that the annual flu vaccine is 70 to 90 percent effective against influenza. What this means is that while a person reduces her or his individual risk of getting the flu after having received the flu vaccine for that year, it is still possible to get sick from the illness. Any immunity from these vaccines is short-lived, however, and with the influenza virus changing each year, vaccination must be repeated annually to continue protection. Whatever protection you do get doesn't kick in until about two weeks after getting the vaccine.
Given that the flu vaccine is in short supply during some flu seasons, certain populations are recommend to get vaccinated first or earlier in the season. It's advised that the following groups of people get the flu vaccine in October and November each year since they are at increased risk for serious complications from the flu, including pneumonia, hospitalizations, and death:
- Individuals who are aged 50 years and older
- Persons with chronic medical conditions (such as heart disease, diabetes, lung disease, asthma, kidney disease, chronic anemia or other blood disorder, endocrine disorder, immunosuppressed conditions, and other problems that restrict pulmonary function)
- Children six months to five years old
- Pregnant women who will be in the second or third trimester of pregnancy during the flu season
- Anyone six months to 18 years of age who is on long-term aspirin therapy
In addition, health care workers, household members or other close contacts, and employees of nursing homes, chronic care facilities, assisted living, and other residences are urged to get the vaccine because their close contact with individuals at risk may cause inadvertent transmission of the influenza virus.
Not everyone is eligible for the influenza vaccine because they may develop serious side effects from getting it. If you have any of the conditions below, consult with a health care provider first:
- Severe allergy to eggs or egg products
- Previous allergic reaction to the influenza vaccine
- Moderate to severe illness with fever (wait until the illness improves)
- History of Guillain-Barre Syndrome
If you do get the flu vaccine, the most common side effect is some mild swelling, redness, and soreness around the area of the injection, which can last one to two days. You may also feel a little achy, with general malaise, fever, and muscle pain lasting one to two days. Despite these possible side-effects, a flu shot is much less dreary than getting a full-fledged case of the flu. Other less likely adverse effects are allergic reactions and the development of Guillain-Barre syndrome, a rare paralytic illness, but this disease is extremely uncommon.

Best of luck as you consider your inoculation options this season!Alice!
