Just for information, I had Pandremix on Monday. From the GSK leaflet:

This vaccine complies with the WHO recommendation and EU decision for the pandemic.

The vaccine contains and 'adjuvant' AS03 to stimulate a better response. This adjuvant contains squalene (10.69 milligrams), DL-alpha-tocopherol (11.86 milligrams) and polysorboate 80 (4.86 milligrams

As far as pregnancy/breastfeeding, it says tell your doctor who will decide if you can be given Pandremix if pregnant, but that it can be used during breastfeeding.
