I've lost count of how many times we've seen the same headline for different variants and relating to different underlying results, and this "less effective" headline always seems to get interpreted by people I talk to as "we'll be back to living like it's 2020 again pretty soon here" rather than the much more accurate "kinda sucks for us collectively but if you and all your close contacts get vaccinated (if!) then it's probably not enough additional risk that you should want to change your behavior".

I notice that I'm also curious what their methodology for coming up with these effectiveness numbers is, and even the "original" public source at https://www.ynet.co.il/news/article/rJQ1O5kp00 doesn't seem to make that clear.
