This is normal. Not all science is as clean and unambiguous as 1+1=2. There's often judgment and interpretation in science. And that's even before science starts getting turned into policy.

It's not our job to be virologists, it's not our job even to be scientists. It is our job to conceptually understand science well enough to know that disagreement between scientists does not imply that one of them is wrong, or that their "expertise" is suspect, or that they're motivated by culture wars.
