The Russian Ministry of Health announced yesterday that doctors at the National Medical Research Center for Radiology administered the country’s first domestically developed personalized mRNA-based cancer vaccine. The patient who received the vaccine is a 60-year-old melanoma patient.
Neooncovac, is the first domestically developed personalized mRNA-based cancer vaccine.

According to Doolly, his therapeutic vaccine, created using the patient’s unique tumor-specific mutations and molecular-genetic characteristics, works as an individualized anti-tumor treatment by encoding neoantigens into mRNA delivered via lipid nanoparticles. It trains the immune system to mount a targeted T-cell response against cancer cells while aiming to minimize harm to healthy tissue.
Neooncovac is authorized for adult patients with inoperable or metastatic cutaneous melanoma, often alongside immunotherapy.
Other countries have been looking into using artificial intelligence in order to create and test cancer vaccines.

mRNA “Vaccines” Facing Backlash?
Personalized cancer vaccines differ fundamentally from conventional preventive vaccines. They serve as therapeutic vaccines designed to treat existing disease by harnessing the patient’s immune system. The approach relies on identifying neoantigens—unique proteins generated by tumor-specific mutations present only in cancer cells. –Doolly
After the injection, the mRNA in the vaccine instructs the patient’s cells to produce neoantigens, then presents them to the immune system. This stimulates a targeted T-cell response and broader immune response, training the body to recognize and eliminate cancer cells bearing the same mutations. Because the vaccine focuses on patient-specific alterations, it aims to minimize effects on healthy tissue while potentially creating long-term immune memory against recurrence.
Russian researchers built on expertise gained from prior mRNA work, including platforms developed during the COVID-19 response.
Who Is At Fault When Americans Distrust COVID “Vaccines?” Russia, Of Course!
Many still don’t trust mRNA vaccines after the rushed COVID-19 injections were all but forced on the public. Perhaps if the science goes in a more favorable direction, people will start to actually trust thsoe who are right now, only making money off of ailments and sicknesses.
