Hi Adianez,
While I’m not a doctor that is qualified to deal with medical issues that can depend on many things (medical history, correlations with other medical issues etc) … there is more about wool allergies in this topic and at the end of post #2 here and there is more about latex allergies in post #2 here.
Based on my research and on an “educated layman’s” opinion … I would consider the risk of developing an allergy to either one by sleeping on a mattress to be “very low”.
