Currently there are three Covid-19 vaccines:Pfizer-BioNTech, The University of Oxford and Astra-Zeneca and Moderna.

Each require two does and full vaccination does not occur until about a week after the second injection.

According to the blurb attached to the video, "BBC health correspondent Laura Foster looks at how much immunity they give, how they prevent infection and which one is better.(2m 39s)" 

I was bothered by the use of the term "better" and her basis for saying this--the evidence, that is. Well, she doesn't (thank goodness). In the end she says that they are not "up against one another" with all playing key roles in ending the pandemic. Otherwise, why would they have been approved? 

I wonder whether an editor wrote this blurb. My guess is yes.
