Doctors now believe herd immunity from COVID-19 could be possible by the spring.
It comes after the FDA gave full approval to Pfizer’s vaccine.
Health officials hope the approval will convince more people to get vaccinated.
They also hope Pfizer’s approval will be the final push companies need to make COVID-19 vaccines a requirement for employees.
Corporations like CVS, Goldman Sachs and Walt Disney World are now requiring vaccinations.
In Ohio, state legislators are debating whether to make it illegal for employers to mandate any and all vaccines.
Ohio Governor Mike DeWine opposes the legislation.
