Flu Vaccine a Closer Match, Time to Get Vaccinated, CDC Says
What sort of flu season is expected this year?
It’s not possible to predict what this flu season will be like. Flu seasons are unpredictable in a number of ways. While flu spreads every year, the timing, severity, and length of the season varies from one year to another.
Flu viruses are constantly changing so it’s not unusual for new flu viruses to appear each year. For more information about how flu viruses change, visit How the Flu Virus Can Change.
The United States experiences epidemics of seasonal flu each year. This time of year is called “flu season.” In the United States, flu season occurs in the winter; flu outbreaks can happen as early as October and can last as late as May. CDC says the flu season begins when certain key flu indicators (for example, levels of influenza-like illness (ILI), hospitalization and deaths) rise and remain elevated for a number of consecutive weeks. Usually ILI increases first, followed by an increase in hospitalizations, which is then followed by increases in flu-associated deaths.
The timing of flu is very unpredictable and can vary in different parts of the country and from season to season. Most seasonal flu activity typically occurs between October and May. Flu activity most commonly peaks in the United States between December and February.
CDC recommends a yearly flu vaccine for everyone 6 months of age and older as the first and most important step in protecting against this serious disease. People should begin getting vaccinated soon after flu vaccine becomes available, if possible by October, to ensure that as many people as possible are protected before flu season begins. However, as long as flu viruses are circulating in the community, it’s not too late to get vaccinated.
In addition to getting a seasonal flu vaccine if you have not already gotten vaccinated, you can take everyday preventive actions like staying away from sick people and washing your hands to reduce the spread of germs. If you are sick with flu, stay home from work or school to prevent spreading flu to others.
Antiviral drugs are prescription drugs that can be used to treat flu illness. People at high risk of serious flu complications (such as children younger than 2 years, adults 65 and older, pregnant women, and people with certain medical conditions) and people who are very sick with flu (such as those hospitalized because of flu) should get antiviral drugs. Some other people can be treated with antivirals at their health care professional’s discretion. Treating high risk people or people who are very sick with flu with antiviral drugs is very important. Studies show that prompt treatment with antiviral drugs can prevent serious flu complications. Prompt treatment can mean the difference between having a milder illness versus very serious illness that could result in a hospital stay.
Treatment with antivirals works best when begun within 48 hours of getting sick, but can still be beneficial when given later in the course of illness. Antiviral drugs are effective across all age-and risk groups. Studies show that antiviral drugs are under-prescribed for people who are at high risk of complications who get flu. This season, three FDA-approved influenza antiviral drugs are recommended for use in the United States: oseltamivir, zanamivir and peramivir.
Encourage your loved ones to get vaccinated. Vaccination is especially important for people at high risk for serious flu complications, and their close contacts. Also, if you have a loved one who is at high risk of flu complications and who develops flu symptoms, encourage him or her to get a medical evaluation. He or she might need treatment with influenza antiviral drugs. CDC recommends that people who are at high risk for serious flu complications who get the flu be treated with influenza antiviral drugs as quickly as possible. People who are not at high risk for serious flu complications who get the flu may be treated with influenza antiviral drugs at their doctor’s discretion. Children between 6 months and 8 years of age may need two doses of flu vaccine to be fully protected from flu. The two doses should be given at least 4 weeks apart. Your child’s doctor or other health care professional can tell you whether your child needs two doses. If your child does need two doses of vaccine to be fully protected, it is a good idea to begin the vaccination process sooner rather than later. VisitChildren, the Flu, and the Flu Vaccine for more information.
Children younger than 6 months are at higher risk of serious flu complications, but are too young to get a flu vaccine. Because of this, safeguarding them from flu is especially important. If you live with or care for an infant younger than 6 months of age, you should get a flu vaccine to help protect them from flu. See Advice for Caregivers of Young Children for more information.
In addition to getting vaccinated, you and your loved ones can take everyday preventive actions like staying away from sick people and washing your hands to reduce the spread of germs. If you are sick with flu, stay home from work or school to prevent spreading influenza to others.
CDC recommends that people get vaccinated against flu soon after vaccine becomes available, if possible by October.
It takes about two weeks after vaccination for antibodies to develop in the body and provide protection against the flu.
Doctors and nurses are encouraged to begin vaccinating their patients soon after vaccine becomes available, preferably by October so as not to miss opportunities to vaccinate. Those children aged 6 months through 8 years who need two doses of vaccine should receive the first dose as soon as possible to allow time to get the second dose before the start of flu season. The two doses should be given at least four weeks apart.
