A vaccine usually takes years, often decades, to develop, but scientists working on potential Coronavirus jabs are hoping to achieve the same huge amount of work in a few months. Neither the Moderna nor the Pfizer/BioNTech vaccines have passed final regulatory approval as yet – but they have different timetables. The Pfizer/BioNTech vaccine, if approved by regulators, will be rolled out sooner but the government still hasn’t promised a launch date. The Prime Minister said he “hoped” the NHS will be able to start distributing the vaccines to those who need it, perhaps even before Christmas. However, Health Secretary Matt Hancock warned that the “vast bulk” of any rollout of the Pfizer/BioNTech jab would be in the new year.
