Important to remember that there is already a vaccine for h5n1. It would need to be updated if it mutates to a point where human to human infections are consistent. It should be faster to get something out than it took for covid.

We cant predict when or even if a process like evolution will produce a certain result. The US and other countries will obviously let it rip so stay safe if it does.
