The development of novel smallpox vaccines using multi - vaccine platforms (i.e., use common vaccine vectors, manufacturing ingredients, and processes) would improve the capacity for rapid vaccine production in response to a smallpox event and reduce the need for stockpiling in the SNS at current levels. ‒ “Given the lack of commercially available orthopoxvirus diagnostics, vaccines, and therapeutics, planning for logistics and supply chain management considerations is critical.

Pneumonia, 2. Muscular weakness, and 3. Hypertension/Angina/Coronary Artery Disease ‒ Two TNX - 102 SL participants experienced an SAE ▪ 1. Renal carcinoma deemed not related to study drug ▪ 2.

Together these studies provide preliminary evidence that TNX - 102 SL is well - tolerated and may promote recovery from PTSD via a pharmacodynamic facilitation of sleep - dependent emotional memory processing
