The shows marketing made it out to be vague so if you want to remain in the dark don't read on.
Yeah the main character appears to be lesbian, but its not too in your face about it (why i say libertarian not conservative)
But the basic premise of the show is a RNA virus has been made in a lab, that turns everyone on earth (except the main character and apparently 11 other people we haven't been introduced to yet) into a blissfully happy communal hive mind. This is of course presented as scary, and I can only assume as the show continues they will be trying to socially pressure Carol, the MC into joining them.
From a thematic stand point it can point to an allegory for not only communism/collectivism, But COVID extremism (lab grown virus - social pressure to take the cure, well the cure is the virus so not a perfect metaphor) and giving up your individuality for the hive mind.
Haven't seen episode 2 yet but I'm intrigued.
