I interviewed med school applicants about their work experience & also had the stress of finding my own DC work experience when she applied to study medicine.
St. John's Ambulance is still taking volunteers, I hope.
Many hospitals are still running work experience programmes (eg Leeds) -- you need to search & search for this in your area.
Things I have seen on applications that were as close as applicants could get include: volunteering with vulnerable people such as care home visitor, helping activity groups for disabled kids, community service roles, shop work, caring for vulnerable family members.
What's important is that whatever similar enough experience the applicant can get, that they can talk about how this experience had overlap experiences with the day to day aspects of being a health professional. Eg., if all they could do was wash someone's hair as a Saturday job, they still had to deal with a human body & keeping a random stranger happy, listening to their needs & preferences, all in 10 minute repeat repeat bursts all day long.
Keep looking & trying & asking around to get her types of WE, but rest assured, many students have only managed very limited WE in last few years.
