We predicted and identified four neutralizing epitopes of HAdV-14 hexon.
The epitopes A14R2 and A14R4 were incorporated into the hexon of HAdV-3.
The antisera against the chimeric viruses can neutralize both HAdV-14 and HAdV-3.
The chimeric viruses could be HAdV-3/HAdV-14 bivalent vaccine candidates.
