I love delicious figures!

These show changes in the relationship between symptom onset and viral load over time among SARS-CoV-2 variants (Fig.3) and the impact of vaccination on peak (lower) and length (shorter) of infectious virus or viral genetic material produced over time (Fig.4)

So I pleased to announce the conceptual spawn of FigTree: PearTree (acronym still to be finalised). If you want to dive right in it is hosted as a web app here: artic-network.github.io/peartree (click the β€œExample...” button for immediate candy and then click every button you can find).

The last part abt how measles disrupts immunity vs other infections is, imo, underappreciated (& mechanism was recently clarified). It's part of why measles vaccination was seen to help beyond just reducing measles complications - not getting measles reduces severity of subsequent infections too.

What Measles Did to My Family My mom always told me that measles was what made my sister sick. I was 8 when she finally explained the whole thing.

The return of measles will mean the return of SSPE.

Controversial Danish vaccine research group faces new allegations Researchers say they couldn’t find complete data for 10 trials that together enrolled tens of thousands of children in Guinea-Bissau

Have I ever mentioned how surreal it is to be an Editor-in-Chief of a journal called Vaccine right now?

It’s pretty wild, at least by typical academic journal editorial office standards.
