A vaccine effective against Zika virus is theoretically possible but may not be delivered anytime soon

Taylor-Robinson, Andrew W

Taylor-Robinson current deficit of knowledge relating to its epidemiology, pathology, and immunology is addressed. Current measures to combat the spread of infection rely on vector control programs, which evidently require improved operation and integrated management. A specific anti-Zika therapy does not exist, but in response to the ongoing epidemic research funds have been committed to develop a vaccine. While prior success in producing effective vaccines against closely related human viral pathogens provides a proof of principle for this approach, vaccine design and clinical testing can be laborious and the timescale long. In the short term, therefore, optimism regarding delivery of a Zika vaccine should be tempered by realism regarding a delivery date.
