Covid winter boosters, new vaccines and why side effects may be different

Everybody aged over 50 is invited for a winter booster jab along with frontline health workers and younger people who are at risk due to health conditions.

If you are getting a winter booster you may be offered a different jab to the variety you have had before. This time, the AstraZeneca (Oxford) vaccine is not being used, only vaccines by Moderna (Spikevax) and Pfizer are offered, or Norovax to a small number who can not have either of those jabs.

The type of Moderna of Pfizer vaccine may be different too. The UK has approved 'bivalent' or 'dual' vaccines from both Moderna and Pfizer, which are half a dose of the vaccines previously used mixed with half a dose of a vaccine that targets Omicron strains. These will be offered to some, while others will get the previous vaccines used in earlier booster jab rounds.
