Some who are hesitant to get vaccinated point to the fact that the vaccines remain under emergency-use authorization rather than full approval. It’s vital for Democratic and Republican leaders to explain clearly and repeatedly that the F.D.A. held these vaccines to such high standards that the only real difference is that full approval requires steps like analyzing longer-term safety and efficacy data, and inspecting manufacturing facilities. Hundreds of millions of doses of these vaccines have now been given to Americans over the past year, providing us with some of the most robust real-world evidence of their safety and efficacy that we’ve ever had for new vaccines. A vast majority of adverse events with the vaccines occur in the first 42 days or so…

[W]e did not predict the politicization of vaccines that has led so many Republicans to hold back. As of mid-July, 43 percent of Republicans said that they have not been vaccinated and definitely or probably wouldn’t be, versus 10 percent of Democrats, according to a poll from The Associated Press-NORC Center for Public Affairs Research. I’m glad former President Trump got vaccinated, but it would have been even better for him to have done so on national television so that his supporters could see how much trust and confidence he has in what is arguably one of his greatest accomplishments.

The vaccines could be a victory lap for the Republican Party, and I call upon all party leaders and conservatives to double down on encouraging vaccination. Party leaders like Gov. Ron DeSantis of Florida are making clear that vaccines save lives. Sean Hannity of Fox News is now telling viewers to “please take Covid seriously.” Representative Steve Scalise of Louisiana shared a photo of himself recently getting vaccinated. I urge more of this from trusted voices on the right.
