Is The Flu Shot A Live Vaccine

Can I Get The Flu Shot If I’m Pregnant

Flu Vaccine Facebook Live Event With David Buchholz, MD

Yes, the CDC recommends receiving a flu shot during pregnancy. In fact, it is recommended that all women who are pregnant or may become pregnant during the flu season receive a flu shot during any trimester. A flu shot protects both the mother and the baby from getting the flu since the mother can pass some of the antibodies onto the baby. Any of the age-appropriate flu shots may be used. It is important that pregnant women only receive a flu shot the nasal spray flu vaccine is not recommended during pregnancy.

Northern Hemisphere Influenza Season

The composition of trivalent virus vaccines for use in the 2017â2018 Northern Hemisphere influenza season recommended by the Advisory Committee on Immunization Practices on August 25, 2017, was:

  • an A/Michigan/45/2015 pdm09âlike virus
  • an A/Hong Kong/4801/2014 -like virus
  • a B/Brisbane/60/2008âlike virus

In addition to these components, quadrivalent vaccines will also include a B/Phuket/3073/2013âlike virus .

In California, some emergency systems were strained by a spike in H3N2 flu cases. In addition, some areas experienced local shortages of oseltamivir. The severity of the flu season seemed somewhat comparable to the 2009â10 swine flu outbreak. A February 2018 CDC interim report estimated the vaccine effectiveness to be 25% against H3N2, 67% against H1N1, and 42% against influenza B.

Are There Any Contraindications To Giving Breastfeeding People The Nasal Spray Vaccine

Breastfeeding is not a contraindication for the nasal spray vaccine. Breastfeeding people younger than 50 years can get the nasal spray flu vaccine as long as they do not have a contraindication to getting that vaccine. See Prevention and Control of Seasonal Influenza with Vaccines: Recommendations of the Advisory Committee on Immunization PracticesUnited States, 202021 Influenza Season for a list of contraindications and precautions for the nasal spray vaccine.

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.

What Are The Benefits Of Flu Vaccination

Misconceptions About Flu Vaccine Effectiveness

Influenza vaccine effectiveness can vary. The protection provided by a flu vaccine varies from season to season and depends in part on the age and health status of the person getting the vaccine and the similarity or match between the viruses in the vaccine and those in circulation. During years when the flu vaccine match is good, it is possible to measure substantial benefits from flu vaccination in terms of preventing flu illness and complications. However, the benefits of flu vaccination will still vary, depending on characteristics of the person being vaccinated , what influenza viruses are circulating that season and, potentially, which type of flu vaccine was used. For more information, see Vaccine Effectiveness How well does the Flu Vaccine Work. For information specific to this season, visit About the Current Flu Season.

Myth #: You Get The Flu From The Flu Shot

“It’s a myth that you can get flu from the flu vaccine,” Schaffner said.

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.

Some people may also mistakenly attribute symptoms of a cold to the vaccine, Schaffner said.

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. “That provides better protection against the real flu, which is of course, is a virus that can make you seriously ill,” Schaffner said.

Myths And Facts About Influenza And Influenza Immunization

Myth: Influenza is not a serious illness.

Fact: In years when influenza is widespread in B.C., hundreds of people may die from influenza or its complications, such as pneumonia. Influenza can lead to serious illness in seniors 65 years and older and in other high risk groups.

Myth: I have never had influenza, so I do not need to get an influenza vaccine.

Fact: Most people can get sick with influenza several times during their lives. An influenza vaccine is the best protection against the influenza virus.

Myth: The influenza vaccines can give me influenza.

Fact: The inactivated influenza vaccine cannot give you influenza. The vaccine contains killed influenza viruses that cannot cause infection.

The live attenuated influenza vaccine given as a nasal spray contains weakened influenza viruses. Common reactions to the live vaccine include mild symptoms such as a runny nose, nasal congestion, cough, sore throat and fever. These symptoms are less severe than those from influenza infection and last a shorter time.

As a precaution, people with weakened immune systems should not get the live vaccine.

Myth: The influenza vaccines cause severe reactions or side effects.

Guillain-Barré Syndrome is a rare condition that can result in weakness and paralysis of the bodys muscles. It most commonly occurs after infections. In rare cases, GBS can also occur after some vaccines. GBS may be associated with influenza vaccine in about 1 per million recipients.

Flu seasons also vary, depending on where you live. Flu season can run from October to May. You should get vaccinated as soon as the vaccine becomes available. It takes about two weeks for the flu vaccine to start working, so you want to make sure you are fully protected as soon as possible. Generally, the seasonal flu vaccine is available from September until spring.

Do I Really Need A Flu Vaccine Every Year

Yes. Everyone aged 6 months and older, without contraindications, is recommended to receive a year flu vaccine. A persons immune protection from vaccination declines over time, so an annual vaccination is needed to get the best protection from flu.

Also, flu viruses are constantly changing, so the composition of the viruses in the vaccine are reviewed each year and updated based on which viruses are circulating and making people sick.

Why Should You Get The Flu Shot

Even though the flu shot isn’t the most effective vaccine, it still provides some protection against infection, especially for healthy people. And most importantly, even at its modest effectiveness, the flu vaccine helps to protect against the worst effects of a flu infection: hospitalization or death.

A 2021 review published in the journal Vaccine found that adults who got a flu vaccine but still got sick were 26% less likely to require intensive care, and vaccinated patients who ended up in the hospital were 31% less likely to die from the flu, compared with people who were not vaccinated.

Why do people sneeze in threes?

The CDC also recommends that people get the flu shot during pregnancy, which changes the immune system, heart and lungs in ways that increase susceptibility to influenza. Between 2010 and 2016, getting a flu shot reduced a pregnant person’s risk of being hospitalized with flu by about 40% compared with unvaccinated pregnant people, according to a 2018 study in the journal Clinical Infectious Diseases. Other studies cited by the CDC suggest that getting a flu shot during pregnancy can also protect the newborn from catching the flu. Flu vaccines are also important for children. Between 2010 and 2014, flu shots reduced a healthy child’s risk of dying from the flu by 65%, according to a 2017 study in the journal Pediatrics.
