As Retroandbeyond, a Master's is still an option.
I know there is at least one university which does a MSc in Pharmaceutical science which only require a 2:2.
Unfortunately, getting a 2:2, especially at this time, is bad news. It will make things more difficult and you may have to settle for less. But try not to worry, concentrate on getting as much experience anywhere you can in anything that relates to where you want to go. Look for volunteer internships in anything related to science or even marketing, and you may find a way in through business experience.
