The GOP congressman and dentist, who is also a member of the Republican Doctors Caucus which advocates for people to receive the Covid-19 vaccine, said he had been fully vaccinated since December.
“I felt better, but I also felt worse,” Babin said, adding that he had started a “treatment regimen” on the advice of his doctors.
Babin, who represents the 36th congressional district of Texas encompassing parts of northeast Houston on the Louisiana border, is among dozens of federal lawmakers who have said they tested positive during the coronavirus pandemic.
Four senators also contracted the virus after being vaccinated.
