Compared with the beginning of the year and with 2020, there was an observable dip in the volume of misinformation in May and June. (Zignal’s research isn’t an accounting of every single piece of misinformation out there, but the spiking of certain topics can be a rough gauge of which themes are most frequently used as vehicles for misinformation.)

The vast majority of people testing positive for the virus in recent weeks, and nearly all of those hospitalized from the coronavirus, were unvaccinated. Public health experts, as well as doctors and nurses treating the patients, say misinformation is leading to some of the vaccine hesitancy.
