As Virus Resurges, G.O.P. Lawmakers Allow Vaccine Skepticism to Flourish

As the coronavirus’s Delta variant rips through conservative communities, most Republicans remain reluctant to confront vaccine misinformation and skepticism in their midst.

WASHINGTON — As the coronavirus surges in their states and districts, fanned by a more contagious variant exploiting paltry vaccination rates, many congressional Republicans have declined to push back against vaccine skeptics in their party who are sowing mistrust about the shots’ safety and effectiveness. Amid a widening partisan divide over coronavirus vaccination, most Republicans have either stoked or ignored the flood of misinformation reaching their constituents and instead focused their message about the vaccine on disparaging President Biden, characterizing his drive to inoculate Americans as politically motivated and heavy-handed. On Tuesday, Representative Steve Scalise of Louisiana, the No. 2 House Republican who said he had received his first Pfizer vaccine shot only on Sunday, blamed the hesitance on Mr. Biden and his criticism of Donald J. Trump’s vaccine drive last year. Senator Tommy Tuberville, Republican of Alabama, said skeptics would not get their shots until “this administration acknowledges the efforts of the last one.”
