Trends suggest we may be in for a second round of this winter’s COVID-19 wave after the initial peak in early January. Flu levels increased this week, too, likely due to more influenza B spread. Read this week's full COVID-19 trends report: bit.ly/4tgFVqY

I remain a tremendous fan of @cp-cell.bsky.social and @cp-cellreports.bsky.social, where I spent 7+ exciting years reading immunology, vaccine and infectious disease work, and lots of other things. Big thanks for all I learned there and pride for all we accomplished together. 🤓🫶

Just imagining how much better it would be if ALL news stories about vaccine-preventable illnesses were illustrated with pictures of people with the disease, not pictures of needle injections. If you must show something that people will find scary & unpleasant, make it the disease, not the cure.

I'm also tired of people using needle shots on stories like this.
