2019-20 Flu Season

Yearly flu vaccination is recommended for everyone 6 months and older. Getting a flu vaccine each year is the best way to help prevent flu and its serious complications. For children, getting a flu vaccine can even be lifesaving.

Flu Activity in the U.S. (Updated on May 28 , 2020)

According to the CDC, flu activity remains low across the country. Flu-like illness also continues to decrease, and the percent of deaths due to pneumonia or flu is decreasing, but is still higher than normal for this time of year. This is mostly due to COVID-19, not flu.

The CDC reports that 179 children have died due to flu and its complications this flu season.

Flu-related hospitalization rates this flu season were highest among children and young adults. In fact, hospitalization rates for children 0-4 years and adults 18-49 years were the highest that CDC has on record for these age groups, even higher than the rates reported during the 2009 H1N1 flu pandemic.

What You Can Do to Help Keep Yourself and Your Family Healthy (For protection against coronovirus, flu and other respiratory diseases)
  • If you are already at the pharmacy or healthcare provider’s office for another reason, ask about getting a flu vaccine.
  • Take everyday preventive actions to stay healthy.
  • Avoid close contact with people who are sick.
  • Avoid touching your eyes, nose, and mouth.

Benefits of Flu Vaccination

Even if the flu vaccine isn’t perfect, getting the flu vaccine every year is still very important. Getting the flu vaccine can:

  • Keep you from getting sick with flu.
  • Help you get back on your feet sooner if you do get sick with the flu.
  • Reduce the risk of children dying from flu.*
  • Reduce the risk of serious flu complications like hospitalization for children and adults.
  • Help protect people around you, including those who are more vulnerable to serious flu illness and complications due to age and/or certain chronic health conditions.
  • Protect women during and after pregnancy.

*A 2017 study published in Pediatrics showed that flu vaccination can significantly reduce a child’s risk of dying from the flu. The study found that half of flu-related deaths in children from 2010 to 2016 occurred in otherwise healthy children – only 22% of these children were fully vaccinated. Nearly 2/3 of children died within seven days of developing symptoms.

Pneumococcal pneumonia is an example of a serious flu-related complication that can cause hospitalization or death. Flu season is good time for people 65 and older, and people with certain chronic conditions, to check with their healthcare provider about pneumococcal vaccinations.

A new CDC study was published on the impact of non-respiratory complications on people who are hospitalized from flu. Results showed that most people had an acute respiratory complication as expected, but nearly half also had a non-respiratory complication. The most common acute non-respiratory complications reported were sepsis, acute kidney injury, and acute cardiovascular events.

The CDC published their first estimates of the 2019-2020 flu vaccine’s effectiveness. So far this season, flu vaccines are reducing doctor’s visits for flu illness by 45% overall and 55% in children. While this protection isn’t as high as we would like, the flu vaccine is providing some protection to those who get it as recommended, and it is currently the best protection we have available. It is important to note that these estimates are only related to the flu vaccine’s ability to prevent outpatient medical visits. Data from studies that are measuring the flu vaccine’s effectiveness against more severe outcomes, such as flu-related hospitalizations or deaths, will be available from CDC at a later date.

Types of Flu Vaccines

Every year, new flu vaccines are created to help protect against the flu viruses that research shows will be most common during the upcoming season. There are different kinds of flu vaccines available including flu shots and nasal spray. Most of the flu vaccines available the 2019-20 flu season in the U.S. contain four flu viruses. The two high-dose flu vaccines, specifically for people 65 and older, contain three flu viruses.

Both CDC and AAP recommend that people get vaccinated with any licensed, age-appropriate flu vaccine. They don’t recommend any one flu vaccine over another.

When to Get the Flu Vaccine

The CDC recommends that you and your family members get a flu vaccine by the end of October each year. Since it takes about two weeks for the flu vaccine to provide protection, it is best for you and your family members to get vaccinated before flu begins spreading in your community. Getting the flu vaccine later in the season is still beneficial and can protect you and your family members from serious flu-related complications.

Some children 6 months through 8 years of age will require two doses of flu vaccine for protection from flu. Children who need two doses of flu vaccine should start the vaccination process as soon as the flu vaccine is available because the two doses must be given at least four weeks apart, and you want to be certain that your children have as much protection as possible before flu begins spreading in your community.


Antiviral drugs are also available for treatment of the flu. If taken early (AS SOON AS YOUR SYMPTOMS BEGIN), antivirals can lessen symptoms, shorten duration of illness, and help prevent severe illness and flu complications.

But, not everyone needs to get antivirals. The people recommended to get antivirals are those who are at higher risk of complications and severe illness from flu including those 65 years and older, young children, pregnant women, and people with chronic health conditions such as heart disease and diabetes. CDC recommends that healthcare providers treat patients with antivirals as soon as they suspect flu, and should not wait for confirmation from lab tests. Learn more.

Common Questions About the Flu Vaccine
Can the flu shot give me the flu?

No. The way that flu shots are made they cannot cause the flu. Flu shots are made from either flu viruses that have been ‘inactivated’ (killed) OR a single gene from a flu virus (instead of the full virus) so they can create an immune response without causing a flu infection.

While some people may get mild side effects from the flu shot like a sore arm, a headache, muscle aches or a low fever, those side effects usually begin soon after the shot and only last 1 -2 days.

Why do some people not feel well or feel like they have flu symptoms after getting the flu vaccine?

The most common side effects from flu shots are soreness, redness, tenderness or swelling where the shot was given.  Some people also report having a low fever, headache and muscle aches. If these reactions occur, they usually begin soon after getting the shot and last 1-2 days.

Besides side effects, there are several reasons why someone might get flu symptoms, even after they have been vaccinated against flu.

  • Some people can become ill from other respiratory viruses besides flu such as rhinoviruses, which are associated with the common cold, cause symptoms similar to flu, and also spread and cause illness during the flu season. The flu vaccine only protects you from the flu, not other illnesses.
  • It is possible to be exposed to influenza viruses, which cause the flu, shortly before getting vaccinated or during the two-week period after vaccination that it takes the body to develop immune protection. This may result in a person becoming ill with flu before protection from the vaccine takes effect.
  • Some people may experience flu like symptoms even after getting vaccinated because they were exposed to a flu virus that is very different from the viruses the vaccine is designed to protect against. The ability of a flu vaccine to protect a person depends largely on the “match” between the viruses selected to make the flu vaccine that season and those spreading and causing illness. There are many different flu viruses that spread and cause illness among people.
