The remarkable global effort to produce a range of Covid-19 vaccines in parallel with developing new treatments – many of which are adapting proven medications for other diseases – is gathering pace. Likewise, there are already treatments emerging that will act as a bridge to getting a vaccine in place. Those conducting vaccine trials are “chasing the disease around the world”; notably in Brazil and the US. China is using a vaccine developed with CanSino Biologics on army personnel though little is known about the type of vaccine involved and extent of deployment. T cell responses have been detected in most Covid-19 patients, and first-in-human vaccine trials have reported potent T cell activation.
