Flu Season This Year: Flu Vaccines & Flu Symptoms
It’s more important than ever to get your flu shot this year. This year’s flu season will overlap with the COVID-19 pandemic, and the two illnesses have similar symptoms. Learn more about the types of flu, flu symptoms and other information, such as when to see a doctor.
Protecting You and Your Family
Getting a flu shot for you and your family is an important part of keeping everyone in your home as healthy as possible this year.
Even if you get a strain of the flu not covered by the vaccine, you will experience milder symptoms and recover faster if you get a flu shot this season. People who get the flu vaccine are less often hospitalized and less frequently develop complications that can lead to death. And getting the flu vaccine can help physicians with a diagnosis should symptoms turn severe.
You need to get a flu vaccine every year. The vaccine is updated each season as needed to protect against the influenza viruses that research indicates will be most common during the upcoming season.
Most major insurance covers the cost of a flu vaccination.
When Is the Best Time To Get the Flu Vaccine?
The flu vaccine takes about two weeks to become fully effective. Learn the best timing to get your shot this year from Robert Salata, MD, Chair, UH Department of Medicine and Program Director of UH Roe Green Center for Travel Medicine & Global Health.

Flu Vaccine for Older Adults
Flu vaccination is especially important for people age 65 years and older because they are at high risk of developing serious complications from flu. A high-dose vaccine is available for these older adults, whose immune response is weaker than those who are younger.
Flu and Children
For children, flu is more dangerous than the common cold. Children younger than age 5 – especially those younger than age 2 – are at high risk of developing serious flu-related complications, as are children with chronic health problems. So annual vaccination against the flu is especially important for youngsters.
The CDC estimates that since 2010, flu-related hospitalizations among U.S. children younger than age 5 have ranged from 7,000 to 26,000. The flu vaccine offers the best defense against flu and its potentially serious consequences and can reduce the spread of flu to others.
The CDC says it’s best for children to receive their flu vaccination by the end of October, but later can still provide protection, as most flu activity peaks between December and February. It takes about two weeks after vaccination for the body to develop antibodies that protect against flu virus infection.
High-Dose Flu Vaccine for Older Adults
Older adults over age 65 have a lesser immune response and so have a special high dose vaccine that improves chances of avoiding hospitalization, death or severe flu symptoms. Robert Salata, MD, chair of the UH Department of Medicine and Program Director of the UH Roe Green Center for Travel Medicine & Global Health, explains.
Influenza in Children
Most children are ill with the flu for less than a week. But those with more serious illness may need to be treated in the hospital.
How the Flu Spreads
Virus-Containing Droplets
Flu viruses spread when people with the flu cough, sneeze or talk, which spreads virus-containing droplets. These droplets can infect others up to six feet away.
By Touching
You also can get the flu by touching a surface or object that has the flu virus on it, and then touching your mouth, nose or eyes. So wash your hands often.
When Am I Infectious?
If you have the flu, you can infect others one day before symptoms appear and up to five to seven days after you get sick. Stay home for at least 24 hours after your fever is gone without the help of fever-reducing medicine, except to get medical care or other necessities.
Flu Symptoms
The flu usually develops suddenly and can often be mistaken for a common cold. But the flu is much more severe and can often lead to serious complications (like pneumonia) if left untreated. Because of this, it's important to understand the warning signs so you can catch it early and get the right treatment. The most common flu symptoms are:
- High fever
- Cough
- Muscle or body aches
- Headache
- Tiredness or weakness
- Stuffy or runny nose
Understanding Flu and COVID-19
The flu and COVID-19 are contagious respiratory illnesses, but are caused by different viruses. Because symptoms for both illnesses are similar – and can range from no symptoms to severe – it can be hard to tell the difference between them based on symptoms alone. Testing may be needed to help confirm a diagnosis.
- What symptoms are different?
-
Signs of COVID-19 that are different from flu may include change in or loss of taste or smell, congestion, nausea or vomiting, diarrhea.
- What symptoms do the flu and COVID-19 have in common?
-
Fever or feeling feverish/chills, cough, shortness of breath or difficulty breathing, fatigue, sore throat, runny or stuffy nose, muscle pain or body aches, headache. Some people may have vomiting and diarrhea, but this is more common in children than adults.
- Is it possible to have the flu and COVID-19 at the same time?
-
Yes, it is possible to have flu, as well as other respiratory illnesses, and COVID-19 at the same time.
- Why is getting a flu shot important during COVID-19?
-
Receiving a flu vaccine prevents illnesses that lead to unnecessary medical visits and hospitalization, which further strain the health care system during the COVID-19 pandemic. By getting vaccinated, you can help preserve health care resources and protect people who are vulnerable to severe illness.
- Who should get a flu vaccine during the COVID-19 pandemic?
-
The U.S. Centers for Disease Control (CDC) recommends annual flu vaccinations for everyone age 6 months and older, with a few rare exceptions, because it is an effective way to decrease flu illnesses, hospitalizations and deaths.

Flu vs. COVID-19: Similarities and Differences
Keith Armitage, MD, Medical Director of the UH Roe Green Center for Travel Medicine & Global Health, talks about how flu and COVID-19 are similar and how they are different.
How Do We Stop a ‘Twindemic?’
This year’s flu season is getting under way against the backdrop of the COVID-19 pandemic. Here are strategies from Robert Salata, MD, Chair, UH Department of Medicine and Program Director of UH Roe Green Center for Travel Medicine & Global Health to avoid two health epidemics at one time.
What If Flu and COVID-19 Are Active at the Same Time?
What happens if flu and COVID-19 are circulating in the community at the same time? Keith Armitage, Medical Director of the UH Roe Green Center for Travel Medicine & Global Health, explains.Flu Treatment
With most cases of flu, you can recover by staying home and limiting contact with healthy people. Drink plenty of fluids and take over-the-counter medicine such as acetaminophen, ibuprofen or naproxen for symptom relief. Never give aspirin to anyone younger than age 19, as this is linked to Reye's syndrome, a serious illness that can damage the brain and liver.
Some people, such as those who are pregnant, older than age 65 or younger than age 2, have certain chronic conditions such as lung, heart, kidney liver problems or a weak immune system, are at higher risk for flu complications such as pneumonia. If this is you, contact your doctor as early as possible in your illness. Your doctor can prescribe an antiviral, which you should take as soon as symptoms start. Antivirals can lessen and shorten the flu.
