Is the flu vaccine less effective than hoped? Preliminary Cleveland Clinic research reveals a surprising result among vaccinated healthcare workers, but doctors caution about limitations.

Scientists have tested in animals a vaccine that may protect against 20 strains of influenza, helping to prevent another pandemic.

The flu vaccine helps protect against viral infections caused by influenza, but there are a lot of other causes of viral syndromes, including adenovirus, rhinovirus, parainfluenza and others.

This is a short series about a recent breakthrough on the road to developing a much sought-after broadly neutralizing vaccine against all influenza A viruses. If successful, it may act as a ...

Influenza A viruses continue to cause seasonal outbreaks year in and year out. Developing a broadly neutralizing vaccine effective against all subtypes has proven challenging. Here, I explain why ...

For over-65s, adjuvanted influenza vaccines – which include an immune-stimulant to encourage a stronger immune response – are recommended over standard influenza vaccine.

An influenza vaccine administered through the nose and constructed with nanoparticles that enhance immune response offers strong protection against different influenza virus strains, according to ...

Moderna has given out the first doses of an mRNA-based influenza vaccine to participants in an early-phase clinical trial, the company announced Wednesday. Moderna ultimately plans to test the ...

Second, the flu vaccine has to combat several influenza viruses which mutate whereas the COVID-19 vaccine targets just one virus.

A better understanding of the immune response to influenza is driving development of vaccines that protect against many strains of the virus.

Flu virus mutates so quickly that one year’s vaccine won’t work on the next year’s common strains. But rational design – a new way to create vaccines – might pave the way for more ...
