UCAS Applications and Personal Statment

For EPQ on my UCAS application what do I name it as? It's about consequences of outbreaks/epidemics like lessons learnt - I've put it as biology on UCAS but is there a better subject/title? it just looks weird having 2 'biology's on my appliciation to me.

Also I am struggling with writing my personal statement and plus unsure of what direction to go on my application. I am applying to biomedical science at 2 unis and the other 2 I am applying to Immunology (+microbiology at one). How do I structure my application without specialsing too much into immunology? I do biology, chemistry and maths + epq.
