In the United States, flu shots are recommended for everyone ages 6 months and older, according to the Centers for Disease Control and Prevention. The flu can be a very serious illness, especially in young children, adults ages 65 and over, those with underlying health conditions, and pregnant women. Strains of the flu virus are constantly changing, so a new flu vaccine is made each year. Scientists make the vaccine before the flu season starts by predicting which flu strains are likely to be the most common during the upcoming season. William Schaffner, a preventive medicine and infectious disease expert at Vanderbilt University School of Medicine.

Both are considered safe and effective, and the CDC recommend getting whichever type is available. Serious allergic reactions to flu vaccines are very rare. The flu can be life-threatening. With prompt treatment, you or your child will make a good recovery. For example, duringflu vaccination prevented an estimated 85, flu-related hospitalizations. A flu shot is the single Naruto konoha senki translation way to avoid getting the flu.

People can visit the CDC's HealthMap Vaccine Finder to find flu shot locations, although they should call the location ahead of time to see if they have the vaccine in stock. So for now, there does not seem to be a particular reason that an older adult should choose a quadrivalent vaccine over a high-dose trivalent vaccine. If it remains higher than expected, then it would be a good idea to contact her usual health providers to ask for advice. Children under 6 months old are at highest risk for complications from the shotx, but they are too reactikns to receive the vaccine. I have not contacted anyone yet, neither my internal medicine doctor or my cardiologist. Both vaccines are also covered percent by Medicare Part B, as long as your doctor, health clinic or pharmacy agrees not Forced to eat creampie cum charge you more than Sbots pays. I agree with all of Adult reactions to flu shots comments. Thank you for your comment, I appreciate it! I would recommend you discuss your questions regarding the likely benefits and risks of flu vaccination with reaftions own doctors. What can you tell me about the flu shots made for seniors? Hello, I work as an RN in a large clinic system deactions is only offering Flublok Quadrivalent vaccine for Adult reactions to flu shots 65 years and older this year in the past they have always offered Fluzone High-Dose. I also had a runny nose and pretty severe frontal headache with a cough at night and fairly severe increased muscle aches for several days.

- Dear Savvy Senior, What can you tell me about the flu shots made for seniors?
- In the United States, flu shots are recommended for everyone ages 6 months and older, according to the Centers for Disease Control and Prevention.
- Many adults may be at increased risk for pneumococcal disease and not know it.
This common infection can also be life-threatening in some cases. Young children, older adults, pregnant people, and individuals with weak immune systems may be more likely to experience dangerous complications. A flu shot contains weakened or inactivated flu viruses that bring the immune system into action without causing illness. These viruses instruct the immune system to make special proteins called antibodies. The body stores antibodies and can use them to fight off a future flu infection.
As a result, a person might be able to avoid the flu completely after receiving the shot, or only get a mild case. Keeping an eye on hygiene and staying home when sick can help prevent the flu. However, most people should also get an annual flu shot. The CDC states that flu shots have a long history of safe use. Most flu shots contain a small amount of egg protein, and egg-free shots are available for those with severe egg allergies. It can be given anytime during pregnancy.
Women who are pregnant may be more likely to have serious complications of the flu due to a higher strain on the heart, lungs, and immune system. A study in the New England Journal of Medicine suggests that a mother might pass some of the protection of the flu shot on to her fetus. As infants cannot get the flu shot until they are 6 months old, this can help protect them during the interim period. The effectiveness of the flu shot can vary widely from year to year and depends on two main factors:.
The flu shot seems to function better in adults and older children. People over the age of 65 years tend to have weaker immune systems, and the shot might be less effective for them. Children under the age of 2 years and people with long-term health conditions might respond less to the shot and receive weaker protection.
A person can receive the shot from the age of 6 months onward. The CDC recommends yearly shots for children under the age of 2 years and over the age of 65 years, especially as they are most likely to experience serious complications from the flu.
Every year, new strains of the flu spread around the globe. There are hundreds of different strains, but the manufacturers of influenza vaccines can only include 3 or 4 types in the shot each year. Medical researchers must narrow it down to the strains that are most likely to make people sick. A few months before flu season arrives, researchers study the flu strains that were most common the year before. They also examine strains that are spreading in other parts of the world.
They use this data to predict which strains of flu will affect people during the upcoming flu season. Sometimes, experts can accurately predict which strains of flu will spread, and the shot is considered a good "match. The to flu shot was a good match, and a study in Clinical Infectious Diseases states that it was 71 percent effective that year. However, in other years, the shot may be a poor match. This happens when flu predictions are inaccurate or the virus changes before flu season begins.
Even when the virus is a poor match, however, the shot may still be helpful. During the flu season, for instance, one of the viruses mutated, leading to a less effective flu shot match. It was also considered to be a particularly severe flu season. Despite these problems, the journal Open Forum Infectious Diseases reports that the shot was 41 percent effective for younger people, and 56 percent effective for people age 65 years and older. Although side effects are usually very mild, the flu shot can cause pain, redness, or swelling at the site of injection.
A small number of people may also experience body aches or a low fever. In rare cases, the flu shot can cause a severe allergic reaction. When this happens, it usually occurs within minutes or hours after the shot is given. The following are signs that require emergency treatment:.
As viruses in the shot are weakened or inactivated, the flu shot cannot give someone the disease. However, it remains possible to contract flu even after getting a flu shot. This may happen as a result of infection with a strain that was not in the shot, or if a person gets the flu before the shot has taken effect.
Those who get a flu shot do not only protect themselves, but also those who might be more likely to experience more symptoms or die from the flu. Infants younger than 6 months, people with long-term health conditions, and older adults may be less likely to get the flu when the people around them get the flu shot. People under 65 years of age typically receive a standard-dose vaccine.
Doctors designed the high-dose version of the shot for people aged 65 and older. Most flu shots are trivalent, which means they contain three strains of flu. Newer vaccines are being developed with four strains, known as quadrivalent shots. Both are considered safe and effective, and the CDC recommend getting whichever type is available. An intradermal shot is available for those who have a fear of needles. It uses a needle that is 90 percent shorter than the standard shot and is injected just under the skin instead of into the muscle.
It is approved for people aged 18 to 64 years. Although a nasal spray version of the flu shot has been available in recent years, a CDC vaccine advisory group reported that it is not effective. The shot takes effect in about 2 weeks, and flu season begins as early as October in some cases. However, people may still benefit from getting the flu shot later, as flu season typically peaks in January or February.
The flu shot is effective for about a year. This means people need a new shot for protection each flu season, even if the strains in the shot are the same. The flu shot is completely safe.
The vaccine must match whichever flu strains are active in that season. All you need to know about flu. Scientists have developed several types of flu vaccine.
Most private health insurance policies cover pneumococcal vaccines. The flu vaccines are recreated every year this begins in early spring , with antigens based on what flu experts expect will be the main circulating strains for the coming flu season. Flu shots protect against three or four strains of flu virus. People do sometimes report body aches, fever, or cough after the flu shot. A: Influenza is a contagious respiratory viral illness, caused by influenza A or influenza B virus. Depending on the year, the Centers for Disease Control CDC estimates that every year, influenza affects million Americans, causes ,, hospitalizations, and results in 12,, deaths.
Adult reactions to flu shots. Flu vaccines for the 2019 to 2020 season
Flu Vaccine Safety Information | CDC
In the United States, flu shots are recommended for everyone ages 6 months and older, according to the Centers for Disease Control and Prevention. The flu can be a very serious illness, especially in young children, adults ages 65 and over, those with underlying health conditions, and pregnant women.
Strains of the flu virus are constantly changing, so a new flu vaccine is made each year. Scientists make the vaccine before the flu season starts by predicting which flu strains are likely to be the most common during the upcoming season. William Schaffner, a preventive medicine and infectious disease expert at Vanderbilt University School of Medicine.
Flu shots protect against three or four strains of flu virus. Quadrivalent flu vaccines — offered for the first time in the flu season — protect against the same strains as the trivalent vaccine, as well as an extra influenza B strain. In addition to the standard-dose flu vaccine given through a needle, flu shots are available in several different forms.
These include a high-dose version for those ages 65 and older; a "cell-based" version that's grown in animal cells rather than hen's eggs and is approved for people ages 4 and older; a "recombinant" vaccine that does not use the full influenza virus or chicken eggs in the production process and is approved for people ages 18 and older; and a nasal spray, which is approved for healthy people ages 2 to 49, but not for pregnant women.
There is also a needle-free flu shot, delivered by a so-called jet injector, which uses a high-pressure stream of fluid to inject the vaccine, the CDC says. It is approved for adults ages 18 to The composition of the flu shot will be slightly different from last season's flu shot. Specifically, there will be a different strain of the H1N1 virus and a different strain of the H2N3 virus in this season's flu shot, compared with last season's shot.
According to the CDC , the trivalent flu shot will contain the following strains of the flu virus:. This year, the World Health Organization held off on selecting the H3N2 component of the flu vaccine for about a month longer than usual, meaning that the agency made its selection in March rather than in February, according to the CDC. The delay gave health officials more time to montior the H3N2 viruses in circulation — which were rapidly changing at the time — and pick the best one for the vaccine.
However, as a result, the delivery of some flu vaccines may be delayed this year. In July, the pharmaceutical company Sanofi Pasteur, which manufactures a large portion of the country's flu vaccine, said that delivery of its flu vaccine will be delayed by three or four weeks, according to the American Academy of Pediatrics AAP. The CDC is once again recommending the spray during the flu season, after not recommending the nasal spray in some previous seasons.
Exactly when the flu season starts and ends is unpredictable, so health officials recommend that people get their flu shot in early fall, preferably by the end of October, the CDC says. Flu activity typically peaks in January or February. Most flu vaccines are given before Thanksgiving, Schaffner said, but people can still get their shot throughout the winter months.
Each season's flu shot expires in June of that year, but Schaffner said that he would consider it "too late" to get a flu vaccine after March, unless a person is traveling to the Southern Hemisphere where the flu season will be starting.
People can visit the CDC's HealthMap Vaccine Finder to find flu shot locations, although they should call the location ahead of time to see if they have the vaccine in stock. The effectiveness of the seasonal flu vaccine depends upon several factors, including how well the flu strains in the vaccine match the strains in circulation.
Some studies show that when strains in the vaccine are a good match with the ones that are circulating, vaccinated individuals are 60 percent less likely to catch the flu than people who aren't vaccinated, according to the CDC. Flu vaccine effectiveness can also vary depending on the person being vaccinated — the vaccine tends to work best in healthy adults and older children, and less well in older adults.
For instance, a study from the CDC found that the year's flu vaccine was not very effective in adults ages 65 and over: Older people who got the vaccine were just as likely to visit the doctor for flu symptoms as those who did not get the vaccine. But other studies suggest that individuals who do get sick develop less serve symptoms if they are vaccinated.
A study published in the journal Clinical Infectious Diseases found that people who got the flu shot were less likely to be hospitalized with the flu. There are some studies that suggest the high-dose flu vaccine provides better protection for older adults. The high-dose flu vaccine contains four times the dose of the standard vaccine, Schaffner said.
A study in the New England Journal of Medicine found that the high-dose vaccine provides 24 percent more protection against the flu than the standard dose, Schaffner said. There are several reasons why it's important for pregnant women to get a flu shot , Schaffner said. In addition, flu vaccination in pregnancy helps to protect the baby against flu during the first six months of life, when the baby is too young to receive a flu shot, Schaffner said.
The mother "passes that protection on to her newborn baby," Schaffner said. According to the CDC, mild side effects from the flu shot include soreness, redness or swelling at the injection site, low-grade fever and aches. Only about 1 percent to 2 percent of people who get a flu shot will have fever as a side effect, Schaffner said. Rare but serious side effects can occur, including allergic reactions. Symptoms of serious side effects include difficulty breathing, swelling around the eyes or lips, hives, racing heart, dizziness and high fever.
If you experience serious side effects, you should seek medical care immediately, the CDC says. For children, side effects from the flu nasal spray can include runny nose, wheezing, headache, vomiting, muscle aches and fever.
For adults, side effects include runny nose, headache, sore throat and cough. These side effects last a short time compared to the actual flu illness, the CDC says. The viruses in the flu shot are killed, so people cannot get the flu from a flu vaccine. However, because it takes about two weeks for people to build up immunity after they get the flu vaccine, some people may catch the flu shortly after they're vaccinated, if they are exposed to the flu during this time period.
The nasal spray vaccine contains a "live attenuated" flu virus, but the virus is weakened so that it cannot cause the flu. The viruses in the nasal spray can't replicate in the warm temperatures of the lungs and other parts in the body.
However, because temperatures in the nose are colder, the virus causes a small infection in the nose. This infection does not cause symptoms in most people, but in some people, it causes symptoms such as runny nose and sore throat, Schaffner said. This local infection will prompt the body to make antibodies against the flu virus, Schaffner said. Children younger than 6 months cannot get a flu shot.
Those who've had a severe allergic reaction to a flu vaccine in the past should generally not be vaccinated, the CDC says. You should not get the flu vaccine if you have a high fever. You should wait until the fever is gone. However, if you have minor illness, like a mild cold or a headache, you can still get a flu shot, Schaffner said.
