I found it all SO bizarre but highly amusing. My understanding of the timeline is:
Nicki tweets that her cousin's friend's testicles swelled after the vaccine, rendering him infertile and resulting in the cancellation of his upcoming wedding.
Prof Whitty is asked about this at the press conference. States it is highly irresponsible. Boris chips in by signposting to a Dr Nikki who is promoting the vaccine. (I thought Boris' response was very witty, excuse the pun, despite being very anti-Boris).
Nicki sends Boris an audio note, in a fake British accent, pretending she went to school with Margaret Thatcher. Claims to love Boris.
Laura K, Political Editor from the BBC, retweets. Nicki calls her 'dumbo'.
Piers weighs in (because, of course he does). Nicki repeatedly and seemingly accidentally calls him Pierce. Brilliant! An actual Dr Pierce then responds to her tweets.
It really made me giggle this evening. I definitely think Nicki will incentivise more and not less people to have the jab... because, well, she doesn't make refusers look good!
