What Are The Benefits Of Flu Vaccination
There are many reasons to get an influenza vaccine each year. Below is a summary of the benefits of flu vaccination and selected scientific studies that support these benefits.
-
Flu vaccination can keep you from getting sick with the flu.
-
Flu vaccination can reduce the risk of flu-associated hospitalization for children, working-age adults, and older adults.
-
Flu vaccination is an important preventive tool for people with chronic health conditions.
-
Flu vaccination has been associated with lower rates of some cardiac events among people with heart disease, especially among those who had had a cardiac event in the past year.
-
Flu vaccination can reduce worsening and hospitalization for flu-related chronic lung disease, such as in persons with chronic obstructive pulmonary disease.
-
Flu vaccination also has been shown in separate studies to be associated with reduced hospitalizations among people with diabetes and chronic lung disease.
-
Flu vaccination helps protect women during and after pregnancy.
-
Flu vaccines can be lifesaving in children.
-
Flu vaccination has been shown in several studies to reduce the severity of illness in people who get vaccinated but still get sick.
What If I Have Recently Been Infected With Covid
Three months.
Data showed that people who had COVID-19 still get a benefit from the vaccine in addition, data showed that waiting some period of time after infection helps maximize the immune response.
Shirley said someone with a weakened immune system might not want to wait that long to get a booster and should discuss their options with a doctor.
Allergic Reactions To The Flu Vaccine
It’s very rare for anyone to have a serious allergic reaction to the flu vaccine. If this does happen, it usually happens within minutes.
The person who vaccinates you will be trained to deal with allergic reactions and treat them immediately.
Anyone can report a suspected side effect of a vaccine through the Yellow Card Scheme.

When Should My Child Get A Flu Vaccine
Doctors recommend that your child get a flu vaccine every year in the fall, starting when he or she is 6 months old. Some children 6 months through 8 years of age may need 2 doses for best protection.
- CDC recommends a flu vaccine by the end of October, before flu begins spreading in your community. Getting vaccinated later, however, can still be beneficial and vaccination should continue to be offered throughout the flu season, even into January or later.
- Children 6 months through 8 years getting a flu vaccine for the first time, and those who have only previously gotten one dose of flu vaccine, should get two doses of vaccine. The first dose should be given as soon as vaccine becomes available.
- If your child previously got two doses of flu vaccine , he only needs one dose of flu vaccine this season.
CDC recommends a yearly flu vaccine for everyone ages six months and older. Pregnant women should get a flu vaccine during each pregnancy. Flu vaccines given during pregnancy help protect both the mother and her baby from flu.
Can You Get The Flu From The Flu Shot

No, you cannot get the flu from the flu vaccines. Flu vaccines given with a needle are made with either inactivated viruses or with only a single protein from the flu virus. The nasal spray vaccine contains live viruses that are weakened so that they will not cause illness.
While some people may experience a low-grade fever or body aches as a side effect, that does not mean the vaccine gave them the flu. For example, if you got sick with the flu shortly after receiving a flu vaccine, it means you were exposed to the flu before your body had the chance to fully develop the antibodies needed. It takes about two weeks after receiving the vaccine before you’re protected against the influenza virus.

Factors In Flu Shot Effectiveness
Influenza viruses are constantly changing and evolving rapidly. Circulating influenza viruses can mutate from one season to the next.
Researchers need to select the specific influenza viruses to include in the vaccine many months before flu season begins. This means whats in the vaccine may not always match whats actually circulating during flu season. This can decrease the effectiveness of the seasonal flu vaccine.
Age can also play a role in vaccine efficacy because your immune system tends to become weaker as you age. The Food and Drug Administration has approved a high-dose flu vaccine for people 65 and older.
The higher dose is aimed at providing a better immune response and therefore better protection within this age group. for those over 65 with the high-dose vaccine.
The CDC also recommends that some children between the ages of 6 months and 8 years receive two doses of the influenza vaccine during the first season in which theyre vaccinated in order to have sufficient protection.
Its still possible to get the flu after being vaccinated, but research has shown that the illness may be less severe and that people who receive a flu shot may be less likely to be admitted to the hospital if they get the flu.
Can A Flu Vaccine Give Me Flu
-
No, a flu vaccine cannot cause flu illness. Flu vaccines that are administered with a needle are currently made in two ways: the vaccine is made either with a) flu vaccine viruses that have been killed and are therefore not infectious, or b) with proteins from a flu vaccine virus instead of flu vaccine viruses . The nasal spray vaccine is made with attenuated live flu viruses, and also cannot cause flu illness. The weakened viruses are cold-adapted, which means they are designed to only cause infection at the cooler temperatures found within the nose. The viruses cannot infect the lungs or other areas where warmer temperatures exist.

When Is The Best Time To Get A Flu Shot How Long Will Its Protection Last
Immunity against the flu tends to wane over the course of a season. You have higher protection a couple of weeks after receiving the shot, compared with four or five months later, so it is a good idea to schedule your vaccine appointment close to the beginning of flu season, and not too early, Dr. Martin said. I tend to get vaccinated in October so my antibodies are ramped up by the time holiday travel begins, she said.
Some people wait longer, until November or December, especially if they are keeping a close eye on cases. But experts agree that it is important to receive the vaccine before cases start to surge. Your body needs at least two weeks after the shot to ramp up its defenses against the flu. People who are more susceptible to severe flu especially older adults, pregnant women and very young children should not delay their shots.
Flu Vaccine Side Effects
Flu vaccines are very safe. All adult flu vaccines are given by injection into the muscle of the upper arm.
Most side effects are mild and only last for a day or so, such as:
- a slightly raised temperature
- sore arm where the needle went in this is more likely to happen with one of the vaccines for people aged 65 and over
Try these tips to help reduce the discomfort:
- continue to move your arm regularly
- take a painkiller, such as paracetamol or ibuprofen some people, including those who are pregnant, should not take ibuprofen unless a doctor recommends it

When To Get The Influenza Vaccine
New season influenza vaccines under the NIP are expected to be available from April. Timing may be different for your local area. Check with your immunisation provider to find out when they will have the vaccine available and when you will be able to book in to have the vaccine.
Annual influenza vaccine should occur anytime from April onwards to be protected for the peak flu season, which is generally June to September. The highest level of protection occurs in the first 3 to 4 months following vaccination.
However, it is never too late to vaccinate since influenza can circulate in the community all year round.
Pregnant women should receive the vaccine at any stage during pregnancy.
Influenza vaccines can be given on the same day with a COVID-19 vaccine.
When Should I Get Vaccinated
For most people who need only one dose of flu vaccine for the season, September and October are generally good times to be vaccinated against flu. Ideally, everyone should be vaccinated by the end of October. Additional considerations concerning the timing of vaccination for certain groups of people include:
- Most adults, especially those 65 years and older, and pregnant people in the first or second trimester should generally not get vaccinated early because protection may decrease over time. However, early vaccination can be considered for any person who is unable to return at a later time to be vaccinated.
- Some children need two doses of flu vaccine. For those children it is recommended to get the first dose as soon as vaccine is available, because the second dose needs to be given at least four weeks after the first. Vaccination during July and August also can be considered for children who need only one dose.
- Vaccination during July and August also can be considered for people who are in the third trimester of pregnancy during those months, because this can help protect their infants for the first few months after birth .

Flu vaccination is important because:
- while flu is unpleasant for most people, it can be dangerous and even life threatening for some people, particularly those with certain health conditions
- more people are likely to get flu this winter as fewer people will have built up natural immunity to it during the COVID-19 pandemic
- if you get flu and COVID-19 at the same time, research shows you’re more likely to be seriously ill

A Flu Vaccine Is The Best Prevention
Flu seasons and their severity are unpredictable. Annual vaccination is the best way to prevent influenza in people ages 6 months and older.
An annual vaccination to prevent flu is the best way to reduce the risk of getting the flu and spreading it to others. When more people get vaccinated, it is less likely that the flu viruses will spread through a community.
The vaccine typically changes each year and contains the four flu virus strains that are expected to circulate in the U.S. during the upcoming flu season. The effectiveness of influenza vaccines varies depending on several factors, such as the age and health of the recipient, the types of circulating influenza viruses, and the degree of similarity between circulating viruses and those included in the vaccine.
The task of producing a new vaccine for the next flu season starts well before the current season ends. For the FDA, its a year-round initiative.
The flu vaccine will trigger your immune system to produce antibodies to protect against influenza disease it will not make you sick with the flu. It can take about two weeks after vaccination for antibodies to develop in the body, which is an important reason to get your flu vaccine early, before flu activity starts.
