The answer, among Democrats across both chambers, is a 100% vaccination rate. For Republicans, it's a different story -- with at least 44.8% of House members vaccinated and at least 92% of senators. In a follow-up to a March House-wide survey and interviews with members, CNN has confirmed that 312 of the 431 members of the House -- just over 72% of the 431-member body -- have now received a Covid-19 vaccination. Of that, all 219 House Democrats have reported being vaccinated. Among the Republican conference, 95 of the 212 members -- 44.8% -- have said they are vaccinated. One hundred and twelve Republican offices did not respond to multiple CNN inquires.
