Richard Doerflinger By Richard Doerflinger • Catholic News Service • Posted June 4, 2021 The COVID-19 pandemic has killed hundreds of thousands of Americans and isolated us from each other as authorities struggle to prevent infections. As vaccinations increase, we see fewer new cases, and a welcome relaxation of some precautions — especially for those who are vaccinated. That raises its own issues. Some predict a two-class society: the privileged who are vaccinated and can resume normal activities, and second-class citizens who must still wear masks and distance themselves from others. That is especially troubling to Catholics who refuse vaccines because of their connection with fetal tissue from abortion.
