The two mRNA vaccines—Pfizer and Moderna—had no impact on overall mortality a re-analysis of trial data shows. While they prevented some COVID-19 deaths this was offset by higher cardiovascular-related deaths for the vaccinated.

The jury is largely out on how big the cardiovascular fallout of the mRNA vaccines will be pending longer-term data on this very new and experimental vax technology.

Does it make sense to apply this mRNA technology to influenza vaccination?

As it stands, public trust in vaccination is far from high with flu vaccination rates for children falling over recent years.

On Vital Signs with Brendon Fallon, we ask how effective flu vaccines are and if mRNA tech is likely to enhance this or add new dangers.
