The Centers for Disease Control and Prevention recommends that everyone ages six months and older receive a flu shot every year. The best time to get vaccinated is during September or October, ensuring that you are protected before the peak flu season, which is typically from December to February.
Understanding influenza
Influenza — commonly known as the flu — is a highly contagious respiratory illness caused by a virus. Each year, approximately eight percent of the U.S. population contracts the flu. The flu vaccine is an effective way to protect yourself and others from this illness.
Optimal timing for the flu shot
While the flu season occurs in the fall and winter, influenza viruses can circulate throughout the year. The CDC advises that the flu activity usually peaks between December and February but can last until May. Therefore, getting your flu shot in the fall is crucial for optimal protection.
What happens if you get vaccinated too early?
Getting vaccinated too early — such as in July or August — may not provide sufficient protection when flu season peaks. The vaccine’s efficacy diminishes over time, so it’s essential to time your vaccination correctly. Ideally, you should wait until September or October to ensure your body has enough time to build immunity.
Exceptions to the rule
Some individuals may need to get their flu shot earlier. For instance, children may require two doses of the vaccine, spaced four weeks apart. Pregnant individuals — especially those in their third trimester — might also consider getting vaccinated earlier to protect their newborns.
What to do if you’re sick
If you are feeling unwell, it is generally advisable to wait until you recover before getting your flu shot. The CDC recommends against vaccination if you have a moderate or severe illness, as a weakened immune system can affect how your body responds to the vaccine.
Why annual vaccination is necessary
Each year, the flu virus evolves and mutates, leading to different strains dominating the flu season. Scientists update the flu vaccine annually to combat these changes, making it essential to get vaccinated every year. Research indicates that flu vaccinations prevented approximately 7.52 million illnesses between 2019 and 2020, significantly reducing hospitalizations.
Additional preventive measures
In addition to getting vaccinated, there are several other ways to prevent the flu:
- Avoid close contact with sick individuals.
- Regularly clean and disinfect surfaces that are frequently touched.
- Cover your mouth and nose with your elbow when coughing or sneezing.
- Wash your hands with soap and water for at least 20 seconds.
- Stay home if you are feeling ill.
- Use hand sanitizer when soap and water are not available.
Getting your annual flu shot is crucial for protecting yourself and others from the flu. Aim to get vaccinated in September or October to ensure you receive the maximum benefit from the vaccine. Stay informed, stay healthy and make your flu shot a priority this season.
