TYLER, Texas, April 8, 2020 (LifeSiteNews) Bishop Joseph Strickland of Tyler, Texas said he will refuse a potential vaccine for the coronavirus if it is made using tissue from aborted children. In a tweet, he expressed his sadness over the fact that even with Covid-19 we are still debating the use of aborted fetal tissue for medical research.
