Remember to schedule your flu shot! Have questions, concerns, or fears?? Please schedule a follow-up with your provider. We are here to answer any questions related to flu shots Tiffany got her first flu shot in office today! She did great and is ready for the holidays. (Photo posted with permission)

There are 7 big reasons to get flu shots

1. The flu shot can be lifesaving.

Depending on the flu virus' severity, deaths as a result of flu complications can range from 12,000 to 79,000 people nationwide. The 2017-2018 season specifically reported close to 80,000 casualties of the flu, according to the CDC.

While anyone can get the flu, certain groups are at increased risk of flu-related complications, including young children, pregnant women, and adults 65 years of age and older. That is why it is essential that these groups get an updated flu vaccine every year.

1. The flu shot can't give you the flu, but it can reduce the severity.

It has been scientifically proven that getting the flu shot won't cause you to get the flu. This is because each vaccine either contains a dead virus or only includes the single gene of the virus, making it inactive. Another common argument for not receiving the flu shot is that each vaccine only addresses a few strains, so you can still contract the flu even after you are vaccinated. Though this may be true, the CDC does extensive research to ensure that the flu shot is highly effective and is protecting you from several of the most common types that year. Furthermore, studies have found that even if you contract the disease, receiving the flu shot can lessen symptoms considerably, making the sickness shorter and more manageable.

3. The flu shot helps protect the people around you.

The flu is highly contagious, so the chance of spreading it to family and friends is extremely likely. Getting the flu shot not only protects you from getting sick, but it also makes sure that those around you, especially those at high risk for infection, remain safe.

4. It may prevent other serious medical complications for people with chronic conditions.

During the 2018-2019 season, 93 percent of adults hospitalized for flu, reported at least one underlying medical condition that placed them at high-risk for complications. Recent research has found that not only has the flu shot reduced the number of people who end up hospitalized by almost half, but it has specifically reduced the number of cardiac events, diabetic emergencies and chronic lung complications.

5. You need a new flu shot annually to stay healthy.

Flu viruses are constantly adapting so each year a new formula is calculated to address the most common predicted types that season. For the best protection, vaccinations should start after 6 months of age, and continue annually.

6. The earlier you get it, the safer you'll be.

Since it takes about two weeks for the antibodies that protect against flu to develop in the body, you should get the flu shot as soon as the season starts. For many, this means before the end of October-beginning November. But it’s better to get it later than not at all, which is why many locations offer the vaccine into January or even later.

7. They are easily and readily available.

Getting a flu shot has become extremely simple and convenient because flu vaccines are offered at many regularly visited locations. Make sure to contact our office at 618-624-2060

Today is National Penicillin Allergy Awareness Day!

Penicillin allergies are often misdiagnosed and that label stays with patients often the rest of their life. This leads to unnecessary avoidance of a very useful antibiotic class, increased cost of care, and higher chance of side effects, and worse outcomes. 95% of these cases we see are not due to any type of allergy and we can simply give again when indicated. This history also does not increase risk for anaphylaxis with future exposure.
Many people are told they're allergic based upon family history, past side effects, or other confusion about risk factors - these are also not reasons to avoid.

At the Allergy, Asthma & Immunology Center we perform Penicillin testing and challenges on average twice a year! It’s very important for any patient with a history of a reaction to come and be evaluated! Please share with family and friends, so many patients are being mislabeled!
