Exavir Bio's New Antibodies Against COVID-19 Armicron Variants
Exavir Bio has introduced XV-R012, a combination of XV-R013M and XV-R014 antibodies that target crucial epitopes in the SARS-CoV spike protein. These antibodies have shown significant potency in neutralizing various coronaviruses and current circulating variants. Exavir Bio's CEO, Dr. Torsten Momin-Rauer, expressed the continuous threat of COVID-19, especially for vulnerable populations like the elderly and immunocompromised individuals. The unique approach of targeting conserved epitopes with XV-R012 is expected to combat a wide range of COVID-19 variants, emphasizing the need for ongoing innovative solutions.
Inhalation vs. Skin Injection for TB Vaccine Delivery
The Jenner Institute at the University of Oxford is conducting a study comparing the efficacy of delivering the BCG TB vaccine through inhalation versus skin injection. The goal is to enhance immune stimulation by matching the natural route of TB infection, which is through inhalation. This study aims to improve vaccine responses, especially in high-risk groups like those with Type 2 diabetes who are more susceptible to TB. These efforts underscore the urgent need for more effective vaccines against TB, a leading cause of global mortality.
Evolution of SARS-CoV-2 Amacron Variants and Immune Response
A study from University College London reveals the evolving traits of SARS-CoV-2 Amacron variants in overcoming human innate immunity. The research highlights the virus's adaptive strategies to enhance human-to-human transmission while overcoming neutralizing antibodies. Understanding these evolutionary mechanisms sheds light on the virus's ability to infect individuals despite existing immunity from vaccinations or prior infections. The findings emphasize the continuous need for surveillance and development of countermeasures against evolving viral threats.
