<h1>NUS Aquaculture Oral Vaccine for Nervous Necrosis Virus 2026</h1> <h2>Disease and research result</h2> <p>NUS researchers reported on <strong>29 June 2026</strong> an oral-vaccine approach that protected farmed fish against nervous necrosis virus (NNV), a disease that can cause major losses in aquaculture. The work addresses disease management in fish farming and is research evidence, not a declaration that NNV has been eliminated from Singapore farms.

An oral delivery method could make vaccination easier to administer at farm scale than individually handling fish, but the announcement does not establish regulatory approval, commercial availability, universal protection across species or a defined deployment date.

It does not by itself change Singapore aquaculture licensing, food-safety rules or vaccination requirements, and it is not a human vaccine or clinical-health intervention.
