My Sims are Sick Constantly

iirc Slice of Life introduces a lot of the sicknesses caused as I use it too and I had noticed as well. You should try vaccinating them as that'll prevent the sickness for a decent amount of time and it'll boost positive moodlets. I think you can prevent sicknesses from occurring too if they're too bothersome for you.

I've noticed this too in the past couple of days! Maybe the 'Rona has spread into the Sims universe?

Are vaccinations part of the mod, or is it possible to get vaccinations with the vanilla game?

Vaccinations are part of the mod.

Vaccinations huh? Thanks for the info. I’ll do that.

Re: Slice of life, you can also remove that particular system by deleting the Sickness system folder from the Slice of Life folder. I did that because I didn't want to deal with that level of reality in my game.

I have noticed this yesterday. All my sims in all households got sick, either with headaches or stomach or others...
And i don't have slice of life or mccc.

My sims are getting sick constantly, as well. I do have Slice of Life, but I have always removed the sickness system because it seemed to make sims sick too often. I feel like I'm playing with it in!

My pets always get so sick. So annoying. My sims have been getting sick too, so I always keep medicine in their inventories now

My sims have been sick a little more than usual as well and I don’t use the Slice of Life mod.
