Serious question: are there 'pandemics' we don't hear about because the virus doesn't hurt us? Are those outbreaks also studied?

If you mean animal flus that didn’t cross over to humans then certainly. Some of them are in wild animals where we might not casually notice a drop unrelated to our activity, or in farm animals where the heavy use of antibiotics reduces the spread within some farms.
