The risks could be higher, but maybe our data is not yet there.

Just as a side note, the risks (and gains) are different, maybe I really don't want a child accidentally, but I don't consider the coronavirus too dangerous to me (it's just a hypothetical, this hypothetical person could be wrong, but in the end we all operate on incomplete data)

In this pandemic, inaction costs lives. The logical and ethical thing to do is evaluate the cost/benefit and choose the path that kills fewer people. You wouldn't say "we should exit the burning house one at a time in case we get hit by a meteor outside, caution here is the logical and ethical thing"; you're making the same kind of logical error, just with a less-absurd difference between the risk of the two options we need to choose between.
