Dr Julian Lewis: How many separate covid vaccines are undergoing trials at present in the United Kingdom, and what is the planned duration of the trial period for each?

[The Secretary of State for Health and Social Care (Matt Hancock): There are three vaccine trials under way in the UK: the AstraZeneca trial, which is frequently discussed; the Imperial College trial; and a trial of the Novavax vaccine. The period of the trial is dependent on the clinical results and on the data. Of course, of those three, the AstraZeneca trial is the most advanced and is in phase 3 trials. We are closely in contact with all of them to ensure that they get the support they need.]
