The goal of this project is to better understand the relationship between tobacco/nicotine and cannabis using behavioral economics during a tobacco/nicotine quit attempt. All participants will receive tobacco/nicotine cessation treatment (smoking and/or vaping treatment) for 12 weeks. To qualify, participants must be between the ages of 18-25 and use tobacco products (smoke cigarettes and/or vape nicotine) and use cannabis (in any form). Participants do not need to be interested in quitting cannabis/marijuana to qualify. This study is being conducted by the Medical University of South Carolina. All procedures are conducted remotely and there is no in-person visits are needed.

Infants and young children are at increased risk for respiratory syncytial virus (RSV) infections because of their maturing immune system and lack of prior exposure to RSV. A genetically stable live-attenuated RSV vaccine (from the US National Institutes of Health) has been shown to be safe and immunogenic in RSV-seronegative children in Phase I studies. A Phase II study is ongoing to evaluate vaccine virus transmissibility to close contacts of study participants (VAD00014 study). Study VAD00004 will be initiated as part of the Phase III development of the RSVt vaccine. The objective of this study is RSVt clinical efficacy, while also further investigating the safety and immunogenicity of the RSVt vaccine in a global context. Vaccine efficacy against lower respiratory tract disease (LRTD) and upper respiratory tract disease (URTD) will be assessed separately, which will provide evidence of protection against RSV respiratory disease if efficacy against both LRTD and URTD is demonstrated.

The purpose of this research is to assess a group-based telehealth parenting program for child ages 2-6 years old with a neurodevelopmental diagnosis and behavior problems. Families will complete an online intake assessment, 6 group-based telehealth PCIT sessions, and an online post intervention assessment. Families will be compensated for their time.
