Resolves Yes if, on the close date, the balance of evidence is that it is possible for one person to spread BCS3-L1 from one person's mouth to another, without doing any preparation beforehand, essentially just by kissing. I will resolve based on my own judgement of what the balance of evidence says. I will not bet.

For context: The FAQ document provided by Lantern bioworks says

Will this spread to everyone I kiss? It’s very unlikely in non-immunocompromised adults

So this would be a no by default. But if there is a confirmed instance of a mouth-to-mouth transmission which seems more credible than not, this would resolve YES.
