Unlocking the Secret to a Healthier Winter: Don't Delay Your Flu Vaccine

Despite the US Centers for Disease Control and Prevention recommendation for all individuals aged 6 months and older to receive the annual flu vaccine, the majority of people have not done so yet. Recent statistics from the CDC as of October 14 reveal that only 22.7% of adults and 20.8% of children have received the flu shot this autumn.

Why is it crucial for every eligible individual to get the flu shot? How effective is it? Is it necessary for individuals who have already had the flu in the past to still get the shot? Why is it necessary to receive the vaccine every year? When is the optimal time to get vaccinated? Additionally, what other precautions should individuals take to maintain their health as the temperature drops?

I sought the assistance of Dr. Leana Wen, our trusted CNN Wellness medical expert, to address these inquiries. Dr. Wen is a proficient emergency physician and holds the position of professor of health policy and management at the esteemed George Washington University Milken Institute School of Public Health. In the past, she also rendered her services as Baltimore's health commissioner.

Dr. Leana Wen advises that flu season has yet to reach its peak. To receive the flu shot, contact pharmacies or doctors' offices in advance and schedule an appointment. While many pharmacies do not require appointments, it is recommended to confirm beforehand. Alternatively, if you have an upcoming doctors' appointment, you may be able to get the shot there, but make sure to check if they have the flu vaccine available. Additionally, your workplace or local health department may provide flu shots as well. Remember, it is important to promptly receive the vaccine from any of these places.

CNN: Why is it crucial for all eligible individuals to get the flu vaccine?

The flu can pose a serious threat, making it crucial to get vaccinated for two key reasons. Firstly, studies from the CDC reveal that receiving the flu vaccine lowers the risk of severe illness, with vaccinated individuals having a 26% lower chance of being admitted to the ICU and a 31% lower risk of flu-related death compared to those who are unvaccinated. In the 2019-2020 season alone, the flu vaccine prevented approximately 105,000 hospitalizations associated with influenza.

Secondly, the flu vaccine helps minimize the spread of infection. Although the effectiveness of the vaccine varies each year based on how well it matches the circulating strains, it generally provides a 40% to 60% reduction in infection rates.

This is significant on a personal and individual level. The flu can make people feel miserable, even if it doesn't lead to hospitalization. Symptoms such as fever, fatigue, body aches, and cough can last for a week or longer. Children may miss school and adults may have to stay home from work and other responsibilities.

To prevent the flu, I make sure that my husband, two children, and I get vaccinated every year. We want to lower the chances of getting sick from the flu. Additionally, getting vaccinated reduces the risk of spreading the virus to others around us. This is especially important to me as a healthcare provider who cares for vulnerable patients.

CNN: Is it necessary for individuals who have had the flu previously to get a shot?

Wen: Absolutely, even if you have had the flu in previous years, it is still crucial to get the flu vaccine this year as your previous immunity diminishes over time.

Furthermore, numerous individuals often claim to have experienced the "flu" when in reality they had a common cold or a different type of viral ailment. Patients frequently assure me that there is no need for them to receive the flu vaccine this year since they have already encountered "the flu." However, it is vital to note that they have never actually tested positive for influenza. It is important to understand that being infected with another virus does not provide immunity against influenza; thus, it remains crucial to obtain the flu shot.

Maintaining good hand hygiene is crucial. It is advisable to frequently wash your hands and use hand sanitizer after coming into contact with commonly touched public surfaces, such as door handles and elevator buttons. In addition, some people may opt to wear masks in crowded indoor spaces.

Furthermore, now is an opportune moment to prioritize your overall well-being. Schedule your annual checkup and ensure that any chronic medical conditions, such as high blood pressure and diabetes, are effectively managed. Additionally, prioritizing sufficient sleep, consuming nutritious meals, and actively working towards reducing stress can significantly enhance your body's resistance to infections.
