A new study shows that fully vaccinated persons are half as likely as those who have not been vaccinated to contract the deadly delta variant. David's diagnosis is just one day after Rep. Ralph Norman (R.S.C.), who has been vaccinated, but opposed the Houses mask mandate announced his positive test.
