Is Moderna vaccine more effective than traditional flu shots?

Question

Hello doctor,

I am a 43-year-old woman, and I have a few questions about the influenza vaccine. With flu season approaching, I want to ensure I am properly protected. Can you explain how the vaccine differs from traditional flu shots? Is it more effective or longer-lasting? I have also heard some concerns about potential side effects. What are the most common side effects, and how do they compare to other flu vaccines? Additionally, I have a family history of autoimmune disorders. Would the vaccine be suitable for me, or should I consider alternative options? I want to make an informed decision while prioritizing my health and safety.

Please help.

Thank you.

Hello,

Welcome to icliniq.com

I understand your concern.

The flu vaccine uses mRNA technology, similar to the COVID-19 vaccine. This method involves using a small piece of mRNA that instructs cells to produce a protein that triggers an immune response. Typically inactivated viruses create an immune response by directly introducing viral antigens into the body. Traditional flu shots are generally 40 to 60 percent effective, depending on the match between the vaccine strains and circulating strains. It is longer-lasting due to the robust immune response elicited by mRNA technology. Typically protect for about six months, needs annual vaccination.

Moderna Vaccine may cause-

Pain.
Redness.
Swelling at the site of injection
Fatigue.
Headache.
Muscle pain.
Chills, fever, and nausea.

Traditional Flu Shots may cause-

Pain.
Redness.
Swelling at injection site.
Muscle aches
Low-grade fever.
Mild fatigue.

mRNA vaccines have shown a good safety profile, but because this technology is newer for flu vaccines, consulting your healthcare provider is crucial, especially given your family history of autoimmune disorders. I suggest getting physically examined by a doctor.

Kindly follow up if you have more concerns.

I hope this helps.
