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.
What’s The Research Behind These Shots Do They Work
Research indicates that high-dose flu vaccines, such as Fluzone High-Dose and FLUAD, have improved a patient’s protection against the flu.
A peer-reviewed study published in The New England Journal of Medicineand sponsored by Sanofi, the company behind Fluzone High-Dose, found that the high-dose vaccine is about 24% more effective than the standard shot in preventing the flu.
An observational study in 2013 found that FLUAD is 51% effective in preventing flu-related hospitalizations for patients 65 and older.
Kristin Englund, an infectious disease physician at the Cleveland Clinic, noted that some hospitals might carry only Fluzone High-Dose because there are more studies on it and it’s been on the market longer than FLUAD.
There are no studies that do a comparative analysis between the two vaccines. There also aren’t any studies that test the high-dose vaccine on younger patients, which is why the FDA licensed the vaccines only for people 65 and older.
Will these super-vaccines cost more money?
Schaffner said that because both vaccines are more elaborate than the normal dose, they cost more to make.
Both Fluzone High-Dose and FLUAD are covered by those who qualify for Medicare with no out-of-pocket cost.
How Effective Is The Flu Shot For Seniors
The flu vaccine is not 100% effective, but its still one of the best ways to prevent the flu, according to the CDC. The regular flu vaccine seems to be less effective in seniors than it is in younger adults. However, PubMed studies have found the high-dose senior flu shot better protects older adults against the flu when compared with the standard flu vaccine.
Getting vaccinated also seems to reduce the severity of illness for people who get sick with the flu, according to the CDC. In fact, researchers have found that flu vaccinations in recent years have reduced the need for flu-related hospitalizations among older adults by 40%.

Can I Get The Flu From The Flu Vaccine
No. The virus thats in the flu vaccine is either dead or for FluMist Quadrivalent extremely weak. Because of this, flu vaccines are unable to cause the flu. However, some people experience flu-like symptoms in the days that follow their vaccine. These are side effects of the flu vaccine, and its a sign your immune system is learning how to fight the flu virus.
After your flu vaccine, you may experience:
A sore, red, or swollen arm
Remember, these are expected side effects and dont mean youre getting sick with the flu. They should go away within a few days.
Unfortunately, its still possible to get sick with the flu after youve received your flu vaccine. It takes about 2 weeks after your vaccine for your immune system to protect you fully. So its possible to catch the flu during that time. And as mentioned earlier, flu vaccine effectiveness isnt perfect. Its also possible to get sick with a strain that wasnt included in the vaccine.
High Dose Vaccine For Flu
Known as Fluzone High-Dose Quadrivalent, the high-dose flu vaccine is the only approved vaccine that consists of an inactivated influenza . Note that the high-dose flu vaccine is a quadrivalent, which means it includes four distinct influenza virus strains that help in killing bacteria in a persons body. Every year, the vaccines specific composition varies in order to match the strains that are likely to circulate throughout flu season.
Below are the strains included for this year:
- Two type A influenza viruses H1N1 and H3N2
- Two type B influenza viruses Victoria and Yamagata lineages

Who Can Receive Fluzone High
In the United States, Fluzone High-Dose Quadrivalent is licensed only for people 65 years and older. Fluzone High-Dose Quadrivalent is not recommended for people with a history of severe allergic reaction to the vaccine or to ingredients other than eggs. Information about vaccine ingredients is located in package inserts from each manufacturer.
Why Is There A Need For Flu Vaccines Designed Specifically For People 65 Years And Older
People 65 years and older are at increased risk of developing serious complications from flu compared with young, healthy adults. This is partly because human immune defenses become weaker with increasing age. During most seasons, people 65 years and older account for the majority of flu hospitalizations and deaths. In the United States, between about 70 percent and 85 percent of seasonal flu-related deaths and between 50 percent and 70 percent of seasonal flu-related hospitalizations have occurred among people 65 years and older. The weakened immune system can also mean that older people dont respond as well to flu vaccination. Given the higher risk of severe flu illness and lower protective immune response after vaccination among older adults, substantial research and development have led to the production of new flu vaccines intended to provide better immunity in this age group.

What Are Fluzone High
Dr. William Schaffner, an infectious diseases specialist at Vanderbilt University Medical Center, said that although the two vaccines have the same outcome, they work a little differently.
Fluzone High-Dose contains four times the antigen that’s in a standard dose, effectively making it a stronger version of the regular flu shot. FLUAD pairs the regular vaccine with an adjuvant, an immune stimulant, to cause the immune system to have a higher response to the vaccine.
The data indicates that no matter what flu strain is out there, it provides more protection for older people, Schaffner said.

Are Quadrivalent Flu Vaccines Safe
Yes. Flu vaccines that protect against four flu viruses have a safety profile similar to seasonal flu vaccines made to protect against three viruses, with similarmostly mildside effects. Like all seasonal flu vaccines, vaccines that protect against four flu viruses are monitored annually for their safety and effectiveness.
Quadrivalent vaccine cannot cause flu illness because they contain inactivated virus, attenuated virus, or are made using recombinant methods that dont use flu virus in the manufacturing process.

Can The Flu Vaccine Make You Sick
While the flu vaccine can give some people mild side effects, it cannot give you the flu. Any side effects are caused by your bodyâs immune response to the vaccination.
The vaccines are made with inactivated viruses and can not get you sick. The most common side effect after vaccination is soreness, redness, tenderness, or swelling where the shot was given. Although uncommon, it is possible to have a low-grade fever, headache, and muscleaches 1-2 days after getting vaccinated.
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.

Senior Flu Shot: What You Need To Know
Each fall, the Centers for Disease Control and Prevention urges Americans to get the influenza vaccine. As the U.S. continues to see the devastating effects of the ongoing COVID-19 pandemic, it is more important than ever to get a senior flu shot. If your loved one is 65 or older, getting a flu shot is still important, even if theyve received a COVID-19 vaccine.
Older adults are at high risk for life-threatening complications from the flu, including hospitalizations and death. The CDC estimates the flu causes 140,000 to 810,000 hospitalizations and 12,000 to 61,000 deaths in the U.S. every year. The CDC also estimates up to 70% of flu-related hospitalizations and 85% of deaths associated with the flu occur in seniors age 65 and older.
Ensuring your senior loved one is protected against the flu can help prevent flu-related complications and hospitalizations. Learn about the different types of senior flu shots, their effectiveness, possible side effects, and how they can prevent flu-related complications.

When Should I Get My Flu Vaccine
Flu vaccine effectiveness can have a lot to do with when you get it. Its recommended to get your flu vaccine about 2 weeks before flu season begins in your area preferably by the end of October. However, if you get the flu vaccine too early July or August, for instance you may not be protected for the entire flu season.
While September or October are the ideal times to get your flu vaccine, its still recommended to get it later than that if you were unable to do so earlier. If youre unsure when flu season begins in your area, talk to your local pharmacist or healthcare provider.
If youve recently received or will be receiving a COVID-19 vaccine including booster doses you dont have to wait a certain time to get the flu vaccine. You can even get them on the same day, if thats more convenient. These two vaccines arent known to interfere with each other.
What Is The Senior Flu Shot
The senior flu shot is a vaccine developed specifically for adults age 65 and older to protect them against the flu virus. According to the CDC, seniors need stronger protection because immune systems tend to weaken with age, putting older adults at an increased risk of serious flu-related complications, such as pneumonia, other respiratory problems, hospitalizations, and even death. The flu can also worsen chronic conditions that are common in seniors like diabetes, asthma, and chronic obstructive pulmonary disease.
The senior flu shot creates a stronger immune response that helps older adults immune systems fight the flu virus more effectively than the regular flu shot. The vaccine works by stimulating the production of antibodies that protect seniors against the virus.
While older adults may get any flu vaccine approved for their age group, two flu vaccines were developed specifically for seniors: the high-dose flu vaccine and the adjuvanted flu vaccine.
