While multiple pharmaceutical companies across the globe are working towards a coronavirus vaccine, there are only a handful which have managed to reach advanced stages of trials. Moderna, which is entering Phase III of its trials in July for its mRNA-based vaccine, is optimistic of receiving FDA approval.
Even the World Health Organisation (WHO) has identified the candidates developed by Oxford University - AstraZeneca and Moderna Inc as front-runners. Moderna has also signed a deal with Catalent for large-scale manufacturing of its vaccine candidate. Catalent will provide vial filling and packaging capacity as well as additional workforce required for 24X7 manufacturing operations. Catalent is already in partnership with Johnson and Johnson as well as AstraZeneca.
While the general opinion of most experts and pharmaceutical companies is that a corona vaccine would be ready by mid-2021, researchers are still hoping for a 2020 breakthrough. The WHO, however, said that they are expecting a COVID vaccine by no sooner than a year.
Johnson and Johnson, Sanofi, Inovio, Sinovac, CanSino are some of the other companies to have made significant progress.

It has received approval from the National Medical Products Administration for clinical trials.
A COVID vaccine developed in Canada's Alberta is moving forward with human trials this summer. Led by University of Alberta researcher Dr John Lewis, Entos Pharmaceuticals has selected two vaccine prototypes for testing in people.
