mRNA burst onto the scene with COVID-19 vaccines, proving it could be designed in weeks and scaled massively.Source 1Source 5 Now, experts eye **universal flu vaccines** using mRNA to target conserved virus parts, dodging yearly strain updates.Source 6

Unlike traditional shots, mRNA instructs cells to produce proteins mimicking flu antigens, training broad immunity.Source 2 In 2026, trials expand to combo vaccines with microneedle patches for easier delivery.Source 2

This evolution promises fewer shots and better variant protection, vital as flu mutates relentlessly.Source 6
