You Can Now Vaccinate Yourself Against the Flu
FluMist, made by AstraZeneca, has been available since 2003. But even though it's relatively easy to administer, it still required a health care professional to give to people. in Sept. 2024, however, the U.S. Food and Drug Administration approved it for at-home use without a health care professional—making it the first flu vaccine that people can give themselves.
Here's what to know.
How does FluMist work?
FluMist is the only nasal vaccine approved in the U.S. It's administered as two spritzes—one in each nostril—and stimulates antibodies against the influenza virus in the nasal passages and bloodstream to protect against serious disease.
It differs from the more popular flu shot option. FluMist uses a weakened form of the influenza virus, while the flu shot contains an inactivated virus. But both annual shots help protect against the worst effects of whatever influenza strain is circulating and causing disease.
Is FluMist as effective as the flu shot?
For most people, the spray and shot are comparable in protecting against serious flu symptoms and hospitalization. FluMist is approved for children and adults from two to 49 years old, since studies show that it's less effective in people 50 and over; their immune systems tend to be weaker. For people over 65, health officials recommended a higher-dose flu vaccine to ensure they receive the maximum protection.

Ultimately, however, the biggest determinant of the efficacy of any flu vaccine is how well matched it is to the influenza strains causing disease in a given season.
How do you vaccinate yourself?
You can order doses for yourself or others in your household at flumist.com in a program the company is calling FluMist Home. Each request is reviewed by pharmacists who partner with AstraZeneca to confirm that you and those you want to immunize are eligible for this type of influenza vaccination. Most healthy people ages two to 49 qualify.
If you are eligible, the nasal sprays are shipped to your home, to arrive at a date you specify. That's important, because FluMist needs to be kept below a certain temperature in order to remain effective.
Once it arrives, you can either use it immediately or store it in the refrigerator. Squirt the spray in each of your nostrils—or those of your family members—and whoever receives it will be vaccinated for the season.
What are the side effects?
FluMist's side effects can differ slightly from those of the flu shot. While the flu shot can cause redness and soreness at the injection site, as well as fever, muscle aches, headache and fatigue, FluMist can cause flu-like symptoms, including runny nose, congestion, sore throat, cough, fever, and muscle aches. That's because FluMist is made from weakened forms of the live virus.

Does FluMist cost more?
Yes, FluMist generally costs more than the flu shot. But all forms of flu vaccination are covered by insurance, so most people will pay about the same amount in any out-of-pocket costs, depending on their insurance plan.
Will FluMist boost vaccination rates?
Doctors and public-health experts are eager to see if the new at-home option for FluMist has an effect on vaccination rates and the number of flu cases in the coming season. Vaccination rates for flu have been declining since the pandemic, including among children. In the 2023-2024 flu season, nearly 45% of adults received at least one dose of the flu shot, compared to nearly 47% in the previous year. There was a similar drop for kids: 55% of children from six months to 17 years old got vaccinated, compared to 57.4% in the previous year. The convenience of vaccinating at home, without the need to make a doctor's appointment or wait at a pharmacy, could address some of the barriers to getting vaccinated—although it likely won't impact growing vaccine skepticism that is contributing to some of the decline in immunization rates.
'We believe firmly that vaccines play a critical role in public health,' said Elizabeth Bodin, vice president of U.S. marketing, sales, and access for respiratory and immunology at AstraZeneca, during an Aug. 14 press briefing. 'Given the reductions in vaccination rates, it's more important than ever that we bring education on the importance of vaccines and break down barriers with FluMist Home.'

Needle-phobic? FluMist nasal spray vaccine available for use at home
More children died from the flu this past season than any year outside of the swine flu pandemic in 2009. Most of them were unvaccinated. That's why some doctors are hoping that the first nasal flu vaccine available for use at home can improve vaccination rates among people, especially children, who are afraid of needles. AstraZeneca's FluMist Home, which was approved last fall, is now available with a prescription for children ages 2 and over, and adults up to age 49. A 2019 review from researchers at the University of Michigan found the majority of children and up to 30% of young adults are afraid of needles. Dr. Zachary Hoy, board-certified pediatric infectious disease specialist at Pediatrix Medical Group in Nashville, Tennessee, said many children are scared because they aren't old enough to understand what vaccines are and why they are important. 'Most of the time, the anxiety and worry before the shot is scarier than the actual shot,' Hoy said. How does FluMist Home work? The vaccine was first approved in 2003 to be given in a doctor's office. However, after the 2009 swine flu pandemic introduced the new H1N1 strain, several studies found the nasal spray was less effective than other flu vaccines. This prompted the Centers for Disease Control and Prevention to recommend against using the nasal spray in 2016. At the time, the CDC said the nasal spray accounted for one-third of all flu vaccines given to children. In response, FluMist's manufacturers reformulated it to more closely match circulating strains, including H1N1, and the nasal spray returned in 2018. Like injectable flu vaccines, FluMist is updated each season based on recommendations from global health officials. 'FluMist's efficacy is comparable to injectable flu vaccines and is a safe and effective needle-free option for flu protection,' AstraZeneca spokesperson Andrew Leone said. Experts say it's too early to tell how bad the upcoming flu season will be. Typically, flu vaccines are 40% and 60% effective in preventing severe illness, and FluMist Home should be equally protective. The doses for the 2026-2027 season contain three virus strains: an A/H1N1 strain, an A/H3N2 strain and a B strain from the B/Victoria lineage, according to the drugmaker. The FluMist Home vaccine contains a weakened form of a live virus to stimulate the immune system. Pregnant women or people with compromised immune systems are advised to talk with their doctor before using it. Does insurance cover it? FluMist Home is available only online. People ordering the nasal spray will need to complete a medical screening questionnaire at that is reviewed by a health care professional, according to the drugmaker. FluMist Home's online pharmacy will then collect the insurance information and bill the health plan directly. A temperature monitor on the packaging will verify that the vaccine has been maintained at the appropriate temperature during shipping and delivery. Green means it's safe to use. Red means it's not. Christina Aungst, senior pharmacy editor at GoodRx, estimates people with insurance will likely only have to pay an $8.99 shipping fee for the nasal spray. 'Currently, if you don't have insurance, FluMist is only available in a health care setting,' AstraZeneca's Leone said. 'We hope to provide a cash pay option for FluMist Home in future seasons.' When FluMist is given in a health care office or clinic, most insurance plans — including Medicare and Medicaid — will cover it. Dr. Scott Roberts, associate medical director of infection prevention at Yale School of Medicine, worries people may not administer the nasal spray vaccine properly without a doctor's supervision. 'What if they have a runny nose? How far back do they need to spray in the nose? What if they store it incorrectly in their house?' Roberts asked. Dr. Kristina Bryant, pediatric infectious diseases physician at Norton Children's in Louisville, Kentucky, and a member of the American Academy of Pediatrics Committee on Infectious Diseases, said the bottom line is that all the available flu vaccines offer comparable protection. 'The most important thing to know is that vaccines only work if they are actually administered,' Bryant said. 'Hopefully, the availability of a vaccine that can be administered in the home will make it easier for some people to be protected against flu.'

America's first needle-free, at-home flu vaccine is now available
There's one less excuse to skip the flu shot this season. Pharmaceutical company AstraZeneca is out with a new version of the flu vaccine, and it makes getting vaccinated easier than ever. The drug can be administered at home, giving you one less reason to trek to the doctor's office. And even better for the needle-averse: You don't need a jab to get it – the vaccine comes in nasal spray form. The drug, which was approved by the FDA last fall, is available now and can be ordered online. While it will cost $70 out of pocket, AstraZeneca says that anyone with insurance coverage will only need to pay $8.99 for shipping. FluMist Home ships in a special cooling container and does need to be stored in a cool environment, so if you order it pop it in your fridge until you plan to administer the vaccine. Flu vaccination rates are on the downswing in the U.S., a phenomenon linked to pandemic fatigue and vaccine misinformatio n. While the flu is an endemic virus that comes back around every year, it can still be dangerous for unimmunized kids, older adults, and people with compromised immune systems. The flu vaccine isn't the only shot that Americans are skipping. From 2019 to 2023, measles vaccination rates fell from 95% to 92%, dipping below the critical threshold for population-level protection. Anti-vaccine activism is rising in the U.S. and that movement now has Robert F. Kennedy Jr., a prominent ally, running the Department of Health and Human Services. On Thursday, HHS announced that it will bring back a task force aimed at scrutinizing the safety of vaccines for children. The Children's Health Defense, an anti-vaccine group founded by Kennedy, called for the task force to be reestablished in a lawsuit against its former leader filed in May.

Nasal spray flu vaccine can now be shipped to your home. Here's how to get it
The first nasal spray flu vaccine, FluMist, can now be shipped to your home. FluMist, made by the drug company AstraZeneca, has been approved in the United States since 2003, but its use was limited to health care settings like hospitals and flu clinics. In 2024, the FDA approved it for at-home administration, making it the first nasal spray vaccine approved for widespread use at home. On Friday, AstraZeneca announced a home delivery service for the product, which infectious disease experts hope will lead to more people getting vaccinated against seasonal influenza. The service is available in 34 states including California, for the upcoming 2025-26 flu season. Prior to the approval for at-home use, FluMust had been given mostly in pediatricians' offices because many children have a fear of needles. As many as 2 in 3 children and 1 in 4 adults have a strong fear of needles, according to CDC estimates. Here's what you need to know about the nasal spray vaccine: It's approved for people aged 2 to 49 Adults can self-administer it; it's given through two sprays, one in each nostril. Children should get it administered by a parent or caregiver. You need a prescription Adults can go to to order the vaccine and will be asked to complete a medical screening questionnaire, AstraZeneca said. A licensed health care provider will review the submission to determine eligibility. Once eligibility is confirmed and insurance is verified, the vaccine will be prescribed and shipped directly to consumers' home on the date they selected. It will come with instructions on how to administer, store and dispose the product. Cost Cost will depend on individuals' insurance, but most insurance plans cover flu vaccines at no cost. There is a $8.99 shipping and processing fee per order. It may not be for everyone Anyone who is wheezing, has asthma, has Guillain-Barre syndrome, has a weakened immune system or has problems with the heart, kidneys or lung should check with their health care provider before getting FluMust, according to AstraZeneca. People who are pregnant or nursing, or who have diabetes, should also check with their doctor first. Children under 5 with a history of wheezing should also check with their doctor. Children and adolescents up to 17 years old who are taking aspirin or medicines containing aspirin should not get FluMust. Side effects The most common side effects are runny or stuffy nose, sore throat and fever over 100 degrees.
