Regulatory approval for a universal flu vaccine by 2028
Research into universal influenza vaccines has accelerated, focusing on conserved viral regions and novel platforms. Clinical trials are progressing, but demonstrating broad, durable efficacy across strains and seasons is challenging.
Regulatory approval requires robust phase 3 results and clear real-world effectiveness. Manufacturing scale and safety data are additional gating factors that may slow timelines even if clinical efficacy looks promising.
My prediction: I expect regulators will not grant full approval for a truly universal adult flu vaccine by March 15, 2028; however, conditional or strain-broadening approvals for next-generation candidates could appear in that window.
