Why Getting the Flu Shot is Important: Insights from Dr. Leana Wen, CNN Wellness Medical Expert
According to the US Centers for Disease Control and Prevention (CDC), everyone aged 6 months and older should receive the annual flu vaccine. However, as of October 14, only 22.7% of adults and 20.8% of children have gotten their flu shot this fall. To understand the significance of the flu shot and address common questions, we interviewed Dr. Leana Wen, CNN Wellness medical expert and emergency physician.
Is it too late to get the flu shot?
Dr. Leana Wen assures us that it’s not too late to get vaccinated. Flu season has not peaked yet, and many pharmacies and doctors’ offices offer flu shots. While some places may require appointments, others may allow walk-ins. It’s important to act promptly and not delay getting the vaccine.
Is there any advantage to waiting until later?
Dr. Wen advises against waiting. It’s best to receive the vaccine before the peak of flu season, which typically occurs between December and March. The flu is already circulating, and you could potentially get infected ahead of peak season. By getting vaccinated now, the vaccine will provide protection throughout this year’s flu season.
Why is it important for everyone eligible to receive the flu shot?
According to Dr. Wen, the flu can be dangerous, and the vaccine has two important benefits. Firstly, it reduces the risk of severe illness. Studies cited by the CDC show that vaccinated patients had a 26% lower risk of intensive care unit admission and a 31% lower risk of death from the flu compared to unvaccinated individuals. In the 2019-2020 year alone, the flu vaccine prevented an estimated 105,000 influenza-associated hospitalizations.
Secondly, the flu vaccine helps reduce the overall infection rate. Its effectiveness varies each year depending on how well it matches the circulating strains, but it typically ranges from 40% to 60%. Being sick with the flu can be miserable, causing symptoms like fever, fatigue, achiness, and cough that can last for a week or longer. By getting vaccinated, you not only protect yourself but also reduce the risk of infecting others, which is crucial for healthcare providers who care for vulnerable patients.
Do people who have had the flu before still need a shot?
Dr. Wen emphasizes that even if you’ve had the flu in previous years, you still need to receive the flu vaccine annually. Immunity wanes over time, and having had another viral infection or cold does not protect you against influenza. To ensure maximum protection, it’s essential to get the flu shot every year.
Why is a flu shot necessary every year?
Dr. Wen explains that the flu shot is recommended annually for two reasons. First, immunity from last year’s shot diminishes over time and won’t provide sufficient protection for this year’s flu season. Second, the strains of the flu in circulation vary each year. The vaccine is specifically targeted to the strains predicted to be most dominant, ensuring the best possible defense against the flu.
When is the best time to get the shot?
According to Dr. Wen, late September to early October is the ideal time to get the flu shot. This timing is before the peak flu season, and the vaccine’s effectiveness will last throughout the winter.
How else can people stay healthy as the weather gets colder?
In addition to getting the flu shot, Dr. Wen suggests maintaining good hand hygiene by washing hands frequently and using hand sanitizer after touching public surfaces. Some individuals may choose to wear masks in crowded indoor settings. It’s also important to prioritize overall health by getting annual checkups, managing chronic medical conditions, getting enough sleep, eating nutritious foods, and reducing stress. These habits strengthen your immune system and overall ability to fight infections.
