Synthetic Chimeric Horsepox Virus ( scHPXV ) Vaccination Protects Macaques from Monkeypox* Presented as a poster at the American Society of Microbiology BioThreats Conference - January 29, 2020, Arlington, VA . ( https://content.equisolve.net/tonixpharma/media/10929ac27f4fb5f5204f5cf41d59a121.pdf ) No monkeypox lesions observed after monkeypox (MPXV) challenge in any of the eight animals vaccinated with TNX - 801 Legend : Cynomolgus macaques (4 per group), were vaccinated via scarification using a bifurcated needle. Two different doses of TNX - 801 ( scHPXV ) vaccine were tested (panel a and b); one dose of TNX - 1200 ( sVACV )(panel c); or vehicle (panel d). After monkeypox (MPXV) challenge, no lesions were seen in any of the 8 animals vaccinated with TNX - 801 (panel a and b). One animal in the TNX - 1200 arm died from unrelated causes, and two of three remaining a nimals showed lesions by Day 69 (panel c). All four vehicle vaccinated animals developed lesions (panel d.) Clinical signs of systemic monkeypox infections w ere seen in all 4 vehicle - vaccinated animals (panel d) by Day 69, but TNX - 801 and TNX - 1200 vaccinated animals were protected. In Panels a - d, blue symbols are male animals an d red are female. Methods : 4 of 4 animals in the 4x10 6 PFU dose, and 3 of 4 animals in the 5x10 5 PFU dose groups exhibited a “take” at Day 7 after a single vaccination. A take is a biomarker of protective immunity. In the TNX - 1200 ( sVACV ) arm only 1 of 4 animals exhibited a take after a single vaccination. The animals that did not present a take were revaccinated on Day 14: the one TNX - 801 animal was revaccinated with 5x10 5 PFU TNX - 801 and the 3 TNX - 1200 animals were revaccinated with 2.4x10 5 PFU TNX - 1200. All but one of the TNX - 1200 animals subsequently produced a take. Tolerability was comparable for TNX - 801 and TNX - 1200. a. b. C. d. TNX - 801 TNX - 801 TNX - 1200
