Had the over-65 autumn booster this morning - was given the Moderna bivalent.
Had expected side effects the following day with AZ1, AZ2, and Pfizer and I expect I shall feel the same, tomorrow, with this new Moderna bivalent (sore arm, chilly, headachy, coming down with flu feeling) but expect to be feeling better by Friday.
There is also a Pfizer bivalent has been recently approved:

A second, “bivalent” vaccine has today been approved as a booster by the Medicines and Healthcare products Regulatory Agency (MHRA) after it was found to meet the UK regulator’s standards of safety, quality and effectiveness.
The updated booster vaccine made by Pfizer/BioNTech, targeting two coronavirus variants, has been approved for use in individuals aged 12 years and above. This decision has been endorsed by the Commission on Human Medicines, after a careful review of the evidence.
In each dose of the booster vaccine, ‘Comirnaty bivalent Original/Omicron’, half of the vaccine (15 micrograms) targets the original virus strain and the other half (15 micrograms) targets Omicron (BA.1) etc.
