Public health measures work!

A brief aside in the latest YLE newsletter:
Interestingly, one specific strain of flu—called Yamagata influenza B—has gone extinct due to Covid-19 measures. This is incredible news because of two things:

  1. It wasn’t thought that we could eliminate a flu strain.
  2. This strain was notoriously difficult to predict for flu vaccine strain-selection purposes.
