Des Moines Register: More than half of all Iowans oppose a new federal effort to pressure millions of American workers into accepting COVID shots, a new Des Moines Register/Mediacom Iowa Poll shows. The new poll comes in the wake of President Joe Biden’s announcement that the federal government will require large employers to mandate COVID vaccinations or test unvaccinated workers weekly. Just 45% of Iowa adults favor the new federal plan, 52% oppose it and 2% are unsure, the Iowa Poll finds.
