World's first synthetic, non-biologic flu vaccine that can be given as a pill has been developed, reveals a new study.
The tablet does not need refrigeration, which makes it easier to transport and suitable for developing countries with warm climates.
Scientists at the University of Cardiff produced the pill by creating synthetic "mirror image" versions of protein molecules.
Scientists claim that this new pill could herald a "revolution in vaccine delivery."
The research was published in the Journal of Clinical Investigation, and has been confined to a proof-of-concept laboratory study.
However, it might take many more years before a non-biological pill vaccine is tested on patients, revealed scientists.
