Who do you think you are kidding? Either you only have the attention span to read 2 paragraphs of an article, or you think if you just lie and only copy the part of the article which is being corrected, no one else will notice?
The European regulations we adopted during our time in the trade bloc are still in effect until the end of 2020.
That includes the rule that says vaccines generally must be authorised by the EMA instead of national regulators.
But as a UK government press release from 23 November 2020 states: “if a suitable COVID-19 vaccine candidate, […] becomes available before the end of the transition period, EU legislation which we have implemented via Regulation 174 of the Human Medicines Regulations allows the MHRA to temporarily authorise the supply of a medicine or vaccine, based on public health need.”
So even if we were still a member of the EU, the UK regulator would have been able to take this decision on its own because EU law already allows it. Incidentally, that legislation took effect in the UK in 2012, long before Brexit was on the cards.
I have seen some shit attempts to win an argument in my time on this forum, but copying and pasting half of an article specifically explaining why you are wrong is up there with the shittest.
