Who knows. Estimates are just estimates based on conditions that are constantly changing.
That doesn't mean you don't make estimates. You have to for planning purposes. You have to make an informed best guess to predict what you are going to have to be ready for.
Businesses operate on reasonable estimates all day, every day. If you are not estimating, you are flying blind in pure reaction mode.
I'd wager we'll have two more "peaks" before we get a vaccine caused by multiple attempts of lifting quarantine. Probably Sept and Jan. Hopefully each will be less than the previous as people slowly learn the hard way to be careful and hopefully we will have developed some palliative treatments.
