I’m more concerned what happens when we bring some microbes from Mars.

  things that go to mars tend to stay there

    That's changing very soon. Perseverance's mission includes collecting and storing samples for a return mission. https://en.wikipedia.org/wiki/Mars_sample-return_mission https://en.wikipedia.org/wiki/Mars_sample-return_mission

      And also things that have gone to Mars in the past have blasted off chunks of Mars into Earth.

  Andromeda Strain makes a good story, but viruses and bacteria tend to evolve with their hosts and environment. It is unlikely that any virus or bacteria brought from mars would have a serious impact on humans or our environment. We probably aren't good hosts to something that's been evolving in martian conditions.

  Interesting, maybe they plan to never bring anything to Earth's surface .. maybe use ISS as an 'air gap'
