Do publications for ST1 applications need to be in the chosen/related specialty to count towards points for application?

Hello!

I'm currently in medical school and am trying to plan ahead with regards to research modules and intercalation. I am interested in applying for cardiothoracic surgery later down the line and was wondering if I will need to have publications in this field at the point of applying for ST1? I have had 6 publications including 1 first-author paper but none have been within this field of medicine. They have all been in immunology.

I'm not quite sure whether my previous publications will contribute any points when I make an application in the future or if I will need very specific research publications in cardiothoracic surgery or something related?
