I accidentally got infected with the wrong virus and I took the cure but it didn't work. Should it have, or will that not do anything for me?

i believe that cures released will only work on the specific skins from the year it was released in. i don't think that there is a cure this year, i think you just have to wait the skin out and save it in the wardrobe.

edit: yeah looks like the antilovirus was for 2012 infections. :c

That's because the Subetan populace has found themselves no longer in need of cures since we've discovered the ability to completely remove our skin and wear skin suits like any other outfit. ^_^

Basically, I'm saying that curing is as easy as going into your Wardrobe, heading towards the beta wardrobe, and clicking the "Skins" tab. It should take you here and then select the "None" option.

I think the beta skins option only works once your virus has been concluded. I'm still in the low stage infection of an infection (Carchari) and it shows me as having no skin selected - basically, I'm already wearing "None". Unless it shows me as uninfected a few moments after posting this when the cache updates, I'm not seeing any change for trying that.

The Bottled Antilovirus will cure all skins now (except 2015)

There's no cure for 2015, so you'll need to wait until you hit the last stage and change your skin to None in the beta wardrobe.
