Is their comment editing going on or did you reply to the wrong comment or is my app glitched? The comment you replied to seems to say:

That’s good to hear that even though the vaccine is targeting the last big Omicron variant (XBB.1.5) aka Kraken, that its still effective towards the new Eris variant as its similar enough.

Which obviously doesn’t make sense for your comment (which I assume was meant to be a reply to an anti-vaxxer or something)
