Not According To Microbiologists
Or you could just stay current witth science news to learn otherwise. Scientists believe bacteria can survive millions of years in a frozen state. That and the spread in travel times from Mars to Earth for meteorites were taken into account in the scientific asessment of this possibility.
And Jo it would take a lot more than a million years for "space flu" to migrate from somewhere else to our solar system as the leading Marslife phobiest and the panspermia champion support. The fact that they push this space flu theory to this day despite decades of rejection and many flu outbreak containments based on accepted medical theory says a lot about their ability to assess reality.
