Are you willing to get the Covid vaccine when offered?

Polls that only measure the people who volunteer to take it are not scientific and should not be used for anything other than entertainment purposes.

I'm not a doctor, but i did take several detailed classes on polling in college, and know that any poll that is open to a large group, but only measures those who volunteer to take the poll isn't really useful.

Sure, you might think that the biases should even out, but that isn't how it usually ends up working in reality.

That Medscape poll might accurately reflect the general population of people was trying to measure, but if it does it is only through coincidence.
