How personalised mRNA vaccines are fighting melanoma

Merck and Moderna reported positive Phase 3 trial results for their personalized mRNA vaccine, intismeran autogene (mRNA-4157), combined with pembrolizumab, showing longer recurrence-free survival in high-risk melanoma patients. The vaccine is tailored to each patient's tumor mutations. Detailed data and regulatory review are pending. Accessibility in regions like India may be challenging due to high costs and infrastructure needs.
