Influenza vaccine uses

Influenza virus ("the flu") is a contagious disease caused by a virus that can spread from one person to another through the air or on surfaces. Flu symptoms include fever, chills, tiredness, aches, sore throat, cough, vomiting, and diarrhea. The flu can also cause sinus infections, ear infections, bronchitis, or serious complications such as pneumonia. Influenza causes thousands of deaths each year, and hundreds of thousands of hospitalizations. Influenza is most dangerous in children, pregnant women, older adults, and people with weak immune systems or health problems such as diabetes, heart disease, or cancer. Influenza virus vaccine is for use in adults and children at least 6 months old, to prevent infection caused by influenza virus. This vaccine helps your body develop immunity to the disease, but will not treat an active infection you already have. Influenza virus vaccine is redeveloped each year to contain specific strains of inactivated (killed) flu virus that are recommended by public health officials for that year. The injectable influenza virus vaccine (flu shot) is made from "killed viruses." Influenza virus vaccine is also available in a nasal spray form, which is a "live virus" vaccine. This medication guide addresses only the injectable form of this vaccine. Like any vaccine, influenza virus vaccine may not provide protection from disease in every person. You may not be able to receive this vaccine if you are allergic to eggs, or if you have ever had a sev...

Public health experts are hoping it won’t be long, however. The advantage of the mRNA platform is that it’s flexible and generalizable. Theoretically, scientists only need to switch out the genetic material, or mRNA sequences, from one virus for another. It’s a matter of figuring out which specific genes will activate the immune system the best—and that’s where researchers have decades of experience with influenza that they didn’t have with SARS-CoV-2. mRNA vaccines should eliminate this mismatch. Because the technology is more flexible, manufacturers can create shots with new genetic sequences in about three months or so. That means that if a bad mismatch occurs during a flu season, scientists could potentially produce a new batch of mRNA flu vaccines targeting the right genetic sequences during the same season . That, in turn, could reduce the hospitalizations and deaths caused by influenza, which still remain relatively high. The virus causes up to 700,000 hospitalizations and 52,000 deaths in the U.S. each year. While an mRNA flu shot would be a huge advance in vaccine technology, there may be other ways to protect people from respiratory illness with combination shots. In a separate trial, Moderna is also investigating combination vaccines that would immunize people against both SARS-CoV-2 and influenza in a single shot.

However, vaccines for respiratory viral infections such as flu are still suboptimal and do not offer broad-spectrum protection. Vaccination against influenza began in the 1930s, with large-scale availability in the United States beginning in 1945.

The vaccine works by causing your body to produce its own protection (antibodies) against the disease. It is also known as a “flu shot”. There are many kinds of influenza viruses, but not all will cause problems in any given year. Therefore, before the influenza vaccine is produced each year, the World Health Organization (WHO) and the U.S. and Canadian Public Health Services decide which viruses will most likely cause influenza infections for that year. The antigens, which are substances that cause protective antibodies to be formed, for these viruses are included in the influenza vaccine. Usually, the U.S. and Canada use the same influenza vaccine, however, they are not required to do so. It is necessary to receive an influenza vaccine injection each year, since influenza infections are usually caused by different kinds of viruses and the protection gained by the vac...

Policy Statement Update — Data Updates The FDA approved an expansion in age indication from 2 years and older to 6 months and older for Flucelvax Quadrivalent (the cell culture-based inactivated influenza vaccine) on October 14, 2021. Data in this Policy Statement have been updated to reflect this change. New or updated data are indicated in bold typeface. This statement updates the recommendations of the American Academy of Pediatrics for the routine use of influenza vaccine and antiviral medications in the prevention and treatment of influenza in children during the 2021–2022 influenza season. A detailed review of the evidence supporting these recommendations is published in the accompanying technical report. Introduction Children consistently have the highest attack rates of influenza in the community during seasonal influenza epidemics. Children play a pivotal role in the transmission of influenza virus infection to household and other close contacts and can experience substantial morbidity, including severe or fatal complications from influenza infection. Children aged <5 y, and especially those aged <2 y, Adults aged ≥50 y, and especially those aged ≥65 y Children and adults with chronic pulmonary (including asthma and cystic fibrosis), hemodynamically significant cardiovascular disease (except hypertension alone), or renal, hepatic, hematologic (including sickle cell disease and other hemoglobinopathies), or metabolic disorders (including diabetes mellitus) Children...
