AttenuBlock: Optimized Immunity
RSV and SARS-CoV-2 are both life-threatening respiratory viruses that inhibit the immune system. Meissa’s AttenuBlock platform generates vaccine candidates that are safe, highly attenuated and specifically optimized to induce a better immune response than natural infection.
For Life and Breath
Respiratory viruses infect people from infancy to old age. Meissa’s RSV and COVID-19 vaccine candidates are designed to prevent infection and disease by inducing mucosal IgA and serum neutralizing antibodies for a multi-pronged, durable immune response.
Live Attenuated Vaccines for RSV and COVID-19
Meissa Vaccines was founded with a mission to protect people everywhere from deadly respiratory viruses and a commitment to develop innovative technologies capable of delivering effective vaccines at a global scale. Meissa is developing live attenuated vaccine candidates against life threatening respiratory viruses, including respiratory syncytial virus (RSV), SARS-CoV-2 (COVID-19), and human metapneumovirus (hMPV). These vaccine candidates have been developed using the company’s proprietary AttenuBlock synthetic biology and codon deoptimization platform. Meissa’s vaccine candidates are formulated to be delivered as a single, intranasal, adjuvant-free, needle-free dose and are designed to prevent infection and disease and generate a strong, durable immune response.
