When To Get The Flu Shot
Flu season typically runs from late fall to early spring.
Flu shots are now available for all Ontarians. You should get a flu shot as soon as possible because it takes two weeks to take effect.
The National Advisory Committee on Immunization now recommends that COVID-19 vaccines may be given at the same time as the flu vaccine.

Vaccines For Adults 65+
Influenza can make older adults very sick. Two vaccines are approved just for seniors to give better protection against the flu. A high-dose flu vaccine is the preferred choice for adults 65 years and older. It protects against four strains of the influenza virus. If this vaccine is not available, then Fluad® is recommended. Both of these vaccines may cause more soreness, redness and swelling where the vaccine was given, lasting a few days longer than the standard vaccine. If neither of these vaccines are available, do not delay in getting vaccinated. All flu vaccines provide good protection.

Testing And Treatment Of Respiratory Illness When Sars
While waiting on results of testing, non-hospitalized persons with acute respiratory symptoms should self-isolate at home. Even if people test negative for both SARS-CoV-2 and influenza viruses, they should self-isolate because of the potential for false negative testing results depending upon what kind of test was done and the level of SARS-CoV-2 and influenza virus transmission in the community. Persons not hospitalized with suspected or confirmed influenza who are at increased risk for complications from influenza should receive antiviral treatment for influenza as soon as possible, regardless of illness duration.
For hospitalized patients, empiric oseltamivir treatment should be started as soon as possible for patients with suspected influenza without waiting for influenza testing results. Get more information on testing and treatment when SARS-CoV-2 and flu viruses are co-circulating.
CDC has developed clinical algorithms that can help guide decisions for influenza testing and treatment when SARS-CoV-2 and influenza viruses are co-circulating.
FDA-approved antiviral medications for treatment of influenza have no activity against SARS-CoV-2 viruses, nor do they interact with medications used for treatment of COVID-19 patients. If a patient who is at higher risk for influenza complications is diagnosed with SARS-CoV-2 and influenza virus co-infection, they should receive antiviral treatment for influenza.
Which Flu Vaccine Is The Most Effective
When flu vaccines are being produced, the strains included are standardized by the FDA. Each 2021-2022 vaccine includes:
Two type B viruses
This means that no matter what vaccine you choose, youre being protected against the same strains. Flu vaccines are typically between 40% and 60% effective from year to year. But when it comes to picking the right flu vaccine for you, you have to take other factors into account.

Individuals With Symptoms Of Covid
During the COVID-19 pandemic, individuals should postpone influenza vaccination until they have recovered if they have:
- acute symptoms of COVID-19
- any symptoms of acute respiratory infection, including minor symptoms such as sore throat or runny nose
This is because they can pose an unnecessary risk to others and healthcare providers if they have COVID-19. Individuals with COVID-19 symptoms should visit a healthcare professional or contact their local public health authority for information on getting tested.
What Is In The Flu Shot
Every year, scientists around the world do their best to get one step ahead of the flu by developing that years iteration of the flu shot. As a reminder, vaccines work by giving your body a chance to fight off an altered version of a virus or bacteria, so that if and when it encounters the live virus in the wild, it already knows how to react, and you never get sick. But whats in a flu shot is a little more complicated.
The recipe starts with the four most common influenza strains from around the world, injected into fertilized chicken eggs or mammalian cells, deactivated so it doesnt give you the actual flu, mixed with a grab-bag of preservatives, antibiotics, and sugars. This combination is then formulated for a shot or spray to make it in time for the 2021 flu season. For those science-is-fucking-awesome types out there, this is indeed awesome.
Its also complex as hell something that keeps virologists on their toes every year. Influenza strains constantly mutate, but scientists get one shot at the annual vaccine, making their best guess some 30 weeks in advance to get the flu shot out to the public.

Why You Need A Flu Vaccine In 2021
Experts are expecting the worst from the 2021-2022 flu season. Flu rates were unusually low last winter, in large part because most people were wearing masks, social distancing, and staying home when feeling sick to prevent the COVID-19 pandemic from getting any worse. But with many people returning to society, and a good portion of them without masks, the flu season could come back with a vengeance this season. The early and strong return of RSV is one sign of this.
Without exposure to the flu last year, people may be more vulnerable than usual this season. Because of this, its crucial to get your flu shot.
If youve taken steps to prevent your kid from getting the coronavirus, youd be hypocritical not to do the same for the flu. So far, 655 children aged 17 and below have died from COVID in 2020 and 2021 combined, according to the Centers for Disease Control and Prevention . In comparison, 199 kids were reported to the CDC to have died from flu during the 2018-2019 flu season alone, and statistical modelling suggests that 434 children may have actually died from the flu that season.
So if you worried at all about your kids during the pandemic, you should make sure they get the flu shot. You should get it too, because the flu kills thousands of adults aged 18-49 each year and sends tens of thousands to the hospital . Theres very little point in avoiding getting COVID during a global pandemic just to get knocked out by the seasonal flu.
I1 New Or Updated Information For 2020
NACI recently reassessed the wording for the recommendation on the vaccination of health care workers and other care providers as a group for whom influenza vaccination is particularly recommended. The existing evidence on HCW influenza vaccination and the reduction of morbidity associated with influenza in patients being cared for by a HCW in health care settings was considered in the context of ethics and acceptability. NACI continues to recommend that, in the absence of contraindications, HCWs and other care providers in facilities and community settings should be vaccinated annually against influenza, and recommends the inclusion of this group among the particularly recommended recipients of influenza vaccine. NACI considers the receipt of influenza vaccination to be an essential component of the standard of care for all HCWs and other care providers for their own protection and that of their patients. This group should consider annual influenza vaccination as part of their responsibilities to provide the highest standard of care.

Are All Influenza Vaccines The Same
While all influenza vaccines will protect against the same 4 flu viruses, different influenza vaccines are manufactured differently and different preparations have different indications as licensed by the FDA. In particular, each vaccine is licensed for a specific age range. All recipients should receive a vaccine that is appropriate for their age. In addition, LAIV is not recommended for use in some populations.
People with egg allergies can receive any licensed, recommended age-appropriate influenza vaccine that is otherwise appropriate. People who have a history of severe egg allergy should be vaccinated in a medical setting, supervised by a health care provider who is able to recognize and manage severe allergic reactions. Two completely egg-free flu vaccine options are available: quadrivalent recombinant vaccine and quadrivalent cell-based vaccine.

When Should I Get A Flu Shot
Getting an annual seasonal flu vaccine can be the best way to protect against getting the flu and help contribute positively to public health. Flu vaccination has been shown to have a lot of benefits, including reducing the risk of getting the flu, being hospitalized and even flu-related deaths in smaller children.
Thats why the Centers for Disease Control and Prevention recommends everyone get a flu shot, especially for those with medical conditions such as asthma, diabetes and chronic lung disease pregnant women people 65 and older or people who live with or care for others who are at high risk of developing serious complications.
Every flu season is different, and so are the vaccines developed each year. The CDC recommends flu shots as soon as the new vaccine is available since it takes about two weeks from the date of vaccination for antibodies to develop against the flu.
What Is The Difference Between Fluzone High
Fluzone High-Dose Quadrivalent contains four times the antigen, the part of the vaccine that helps your body build up protection against flu viruses, than Fluzone Quadrivalent and other standard-dose inactivated flu vaccines. The higher dose of antigen in the vaccine is intended to give people 65 years and older a better immune response to vaccination, and therefore, better protection against flu. Both Fluzone High-Dose and Fluzone Quadrivalent are produced by the same manufacturer and are quadrivalent vaccines. There are a number of other flu vaccines produced by other manufacturers.

Flu Vaccine Ingredients: The Strains
Every year, vaccine developers take virus samples from labs across the world and mix and match them. This years vaccine relies on four viruses this is called a quadrivalent vaccine. The four viruses in the vaccine are somewhat different for the three different types of flu vaccines, which are egg-based , recombinant, and egg-free.
Those viruses are
First, lets break down the terminology: A refers to the type of influenza that infects birds, humans, pigs, horses, seals, and dogs H#N# refers to the different proteins found in the outer shell of the virus pdm is short for pandemic and 09 is the year of said pandemic .
This years Apdm09 component is different for flu vaccines that are egg-based compared to those that are cell-based and recombinant-based. For egg-based vaccines, the component changed from an A/Guangdong-Maonan/SWL1536/2019 pdm09-like virus to an A/Victoria/2570/2019pdm09-like virus. That means a flu strain akin to the one seen in the 2009 pandemic that was created in 2019 in a lab in Victoria is replacing the strain created in 2019 in the Maonan district of Guangdong.
For cell-based and recombinant vaccines, the component changed from an A/Hawaii/70/2019 pdm09-like virus to an A/Wisconsin/588/2019 pdm09-like virus.
The second component is a variant of the 2009 H1N1 swine flu. H3N2 was first found in pigs in 2010, then in humans in 2011. The biggest human outbreak was in 2012 with some 309 reported cases.
Can Seniors Get A Covid
COVID-19 vaccines and booster shots may cause side effects similar to senior flu shots. It is still unknown whether coadministration of these vaccines leads to more reactivity to ingredients, sensitivity, or side effects, according to the CDC.
If youve received or are planning to receive a COVID-19 vaccine or booster along with a senior flu shot, heres what you need to know:
- After at least six months of receiving the second dose of the Pfizer-BioNTech vaccine, you are eligible for a booster shot.
- If you received Moderna or Johnson & Johnson vaccines, you are currently not eligible for a booster shot.
- The Pfizer-BioNTech booster shot has been authorized for people 65 and older and for high-risk individuals.
- Getting the senior flu shot will not offer protection against COVID-19 and vice versa.
- COVID-19 vaccines may be administered with flu vaccines, although it is still unknown whether vaccine side effects increase with coadministration, according to the CDC.
You should first consult your loved ones doctor to figure out what could work best for them.

Can I Get The Flu Once Ive Gotten The Vaccine
Even if you do get the vaccine, it isn’t 100 percent effective, and theres no guarantee itll keep you from getting the flu. Thats because the virus is extraordinarily promiscuous, according to Dr. Poland. Its constantly mutating and changing, meaning that the vaccine you get could be protecting you from four different strains of the flu but if you run across a fifth strain, you could still get sick.
For example, In 2000, we had exactly the right combination of flu strains in the vaccine, Dr. Poland says. “Then, out of nowhere, in November, there was a new strain, and people had no protection.
Still, some protection is better than none at all. With so many different types of influenza virus out there, its best to be protected against as many as possible.
People At High Risk Of Influenza
- All children 6 to 59 months of age
- Adults and children with the following chronic health conditions:
- cardiac or pulmonary disorders
- diabetes mellitus and other metabolic diseases
- cancer, immune compromising conditions due to underlying disease, therapy, or both, such as solid organ transplant or hematopoietic stem cell transplant recipients
- renal disease
- neurologic or neurodevelopment conditions, including:
- seizure disorders

Flu & People 65 Years And Older
People 65 years and older are at higher risk of developing serious flu complications compared with young, healthy adults. This increased risk is due in part to changes in immune defenses with increasing age. While flu seasons vary in severity, during most seasons, people 65 years and older bear the greatest burden of severe flu disease. In recent years, for example, its estimated that between 70 percent and 85 percent of seasonal flu-related deaths have occurred in people 65 years and older, and between 50 percent and 70 percent of seasonal flu-related hospitalizations have occurred among people in this age group.
Seasonal Flu And Covid
Flu and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a coronavirus and seasonal flu is caused by infection with one of many influenza viruses that spread annually among people.
Because some symptoms of flu and COVID-19 are similar, people may need to be tested to tell what virus is causing their illness. People can be infected with both a flu virus and the virus that causes COVID-19 at the same time. In general, COVID-19 seems to spread more easily than flu and causes more serious illnesses in some people. Compared with people who have flu infections, people who have COVID-19 can take longer to show symptoms and be contagious for longer. This FAQ page compares COVID-19 and flu, given the best available information to date.
Yes. It is possible to have flu and other respiratory illnesses like COVID-19 at the same time. Health experts are still studying how common this is. Some of the symptoms of flu and COVID-19 are similar, making it hard to tell the difference between them based on symptoms alone. Diagnostic testing can help determine if you are sick with flu or COVID-19.
Your health care professional may order a test to help confirm whether you have flu or COVID-19 or some other illness. Get more information on COVID-19 and flu testing and symptoms of COVID-19 and flu.

The following is a summary of recommendations from the National Advisory Committee on Immunization .
Iv4 Simultaneous Administration With Other Vaccines
In general, NACI recommends that two live parenteral vaccines be administered either on the same day or at least 4 weeks apart Footnote 166. This recommendation is based largely on a single study from 1965 that demonstrated immune interference between smallpox vaccine and measles vaccine administered 9-15 days apart. Subsequent studies have revealed conflicting results on immune interference between live vaccinesFootnote 167, Footnote 168, Footnote 169Footnote 170. No studies were found on potential immune interference between LAIV and other live attenuated vaccines administered within 4 weeks. A few studies on concomitant administration of LAIV3 with MMR, varicella, and oral polio vaccines did not find evidence of clinically significant immune interferenceFootnote 10, Footnote 12, Footnote 13. One study reported a statistically significant but not clinically meaningful decrease in seroresponse rates to rubella antigen when administered concomitantly with LAIV.
