I sure hope not, because such an event could kill millions or even billions.

Unfortunately, humans are involved. I say YES!

I think:

1) Biology is too complex and too "evolvy" too be targeted on 1 person or group of people

2) There aren't a lot of mad scientists who want to destroy world

So at most there will be secret developments

Would sars-cov2 have counted?

@lukres no, as it was never intended as a weapon or used in an attack

@TheWabiSabi Not that we know, at least

@mariopasquato true

What is the resolution criteria?

@Cytokine let's say:

• Used in an attack and killed at least 1 person

• Compount was unknown before

@SjoerdSpendel Does it have to be a deliberate attack or would accidental release/exposure count. And would a modified version of a prior/natural vector count.

@Cytokine both yes. But I needs to a new modified version. So the modification needs to be new.
