Masking should be encouraged b/c both vaccinated & unvaccinated can spread Delta to other unvaccinated persons, who are quickly filling up hospitals. There’s nothing wrong w/ decreasing transmission while encouraging vaccination. #GetVaccinated #MOLeg #MaskUp

If you haven’t already done so, get vaccinated.

Wear a damn mask.
