Perceptions of the safety of the J&J covid-19 vaccine...

..before CDC recommended a pause on shots:
Safe - 52%
Unsafe - 26%

...after CDC recommendation:
Safe - 37% (-15)
Unsafe - 39% (+13)

Unfortunately no, only J&J

What I'm super curious about is this chart...

If I take the Economist/YouGov poll, sale the J&J safe/unsafe question as a scale from -2 to 2, and then plot the trend over the course of the poll, there seems to be a large dip on Monday too. Any ideas?

Yes, and overall vaccine hesitancy still trended down in the same Economist/YouGov data this week

With no statistically significant differences pre- and post- J&J announcement

(for comparison's sake, here is the margin of error on the change in attitudes toward J&J)

man, manutral experiments are cool

Perceptions that the J&J vaccine is unsafe rose among Democrats, Republicans, and Independents after the CDC recommended pausing its use on Tuesday

But there are no statistically significant effects on hesitancy among each group
