The first couple episodes of the season weren't perfect but very excited and were very excellent at ramping up the tension. However, it all comes to a halt in this episode. The episode turns into an ad for vaccinations and uses it extremely poorly and just as a brief intermission from what's been building in the early part of this season. I don't hate social commentary, I think it can be very important for the audience but only if it's done right. This episode did not do it right; social commentary has to be subtle, it can't be thrown in the face of the viewer in the most obvious way possible. And when you have every character in the show asking each other if they have been vaccinated at least 5 times each, it's pretty easy to understand what the writers were trying to get at. It's disappointing that such a promising show has turned into shoveling the writers opinions and beliefs down the audiences throats. I hope the show will pick back up after this disappointing intermission of an episode.
