New method places inactivated viruses directly into mice’s gums



Summary

A novel method directly applies inactivated viruses to mice’s gums, offering a potentially efficient and less invasive way to trigger immune responses. Unlike traditional injections, this “gum immunization” allows for quicker immune cell activation and antibody production. Researchers found this method effective in inducing both local and systemic immunity, protecting the mice from subsequent viral challenges. This approach holds promise for developing more accessible and effective vaccines, particularly against viruses that enter through mucosal surfaces, like those affecting the respiratory or digestive systems. This technique could simplify vaccine administration and improve protection against various infectious diseases.
