They're not. You are looking at average efficacy against Influenza A, which is 43%. The efficacy versus Influenza B is 73%. Combined, these provide an "overall" protection of roughly 48%, because this year, there are more cases of A than B.

It's difficult to project the overall spread or transmission rate of a particular Flu virus ahead of time. Human's move around in fairly predictable patterns at the macro level, but are very hard to pin down individually over the course of any particular season. A total efficacy of 48% is pretty good actually, as the vaccine is designed to provide some protection against multiple Influenza strains. Sometimes, as was the case during the 2014-15 season, the vaccine is not a good match for the actual spread of influenza in the wild. That year, the vaccine was only about 19% effective.

Has anyone ever thought that maybe the Flu Shots being doled out each year are what's responsible for all of the mutations, with each year seemingly more intense and widespread than the previous year?
I'm no immunologist or backgrounded in science but what exactly would trigger a virus to mutate to something new each and every year and why is the strain only valid for a single year?

#..if we can map a human genome we can surely figure out the biology of a virus that sure-as-rain, shows up around the same time, each and every year.

I'm turning 49 this year. Never had the jab. Never had the flu
