Reading the OP honing in on Scorpio with immune diseases - I thought to add the natal chart (AA rated for correct time) of child star and later Teen starlet,
Annette Funicello.
Annette started out on
the original Walt Disney "Mouseketeers Club" which use to be on TV in the 1950s, practically everyday. For those of us born in the same era, we'd gather around the TV and anxiously await another episode of the children's show.
When she entered her teenager years, she became very popular especially in the California era of surfing movies, such as "Beach Blanket Bingo" and other teenage flicks in which she starred. She once said, " Mr. Disney asked me to not wear a bikini " reminding her she had her "image" at stake.
I think they negotiated and she wore a two piece which wasn't so bare as others that were available then.
The teenage male stars all fell in love with Annette, from Paul Anka, a famous singer & song writer from Canada, to Frankie Avalon, the U.S. singing star.
Annette was also very serious about her religion she grew up in, being Roman Catholic. It must have been a terrible time for her to divorce when she did, her 1st husband Frank Girardi, another Italian American like she was, who also was in movie business as a talent agent.
They stayed married long enough to have 3 children born to them; and the kids were older when they divorced.
Her 2nd husband was older and was her coach for horseback riding, teaching her and also taking care of her own horses she owned.
He ended up being 1,000% devoted to Annette, taking care of all her physical needs even during the dark days, just him with one Mexican lady took care of Annette until her death.
Annette as you'll see was a Scorpio Sun- perhaps the IMMUNE SYSTEM was depleted and we'll be able to learn more about MS (Multiple Sclerosis) by study of her chart.
I have an astrologer friend who has M.S. and like Annette came down with it around the same age in her life. Like Annette, she too had 3 children - and like Annette, she is now graduated to the wheelchair 100% of the time. It is rapidly depleting her energies, and being a Sun in Leo, a bit of an extrovert, it is very very sad to see or hear about especially knowing from Annette how it may end up for her too.
This bio is not correct - (if anyone wants to inform them), Annette did NOT have children with her 2nd husband. Her only children born to her were with the first husband, and that totaled 3 of them.
I've noticed many errors lately which is sad on Astro.com which used to be a stickler for accuracy.
Anyway,
Glen Hold (the 2nd husband) may have had 3 of his own before marrying Annette. He was much older then she was. Following her life as I did or tried to do as she went through these terrible times, including her home in Beverly Hills with Glen, "catching on Fire" and the M.S. already known about - must have been horrendous times for them.

The former Disney Mouseketeer has been in declining health with multiple sclerosis, according to City News Service.
Forty-five firefighters were sent to 3100 block of N. Fond Dr. at 7:21 a.m., and put out the fire in 24 minutes, Erik Scott of the Los Angeles Fire Department said.
Since the fire was in 2011, and she died in 2013 - I forgot just how short a period, she was in the new home they moved to.
