First of all you are confusing two different infections. The STD form of chlamydia does not cause pneumonia in adults although it can cause babies born to infected mothers can get eye infections and pneumonia from chlamydia.
Chlamydophila pneumoniae

Next it has been well known for years and long before 2009 that the flu presented a higher risk of developing a secondary pneumonia infection. I dont know where you are getting 2009 from but it is simply not supported.
2009, if that year is correct, marks the pharma industry's push to inoculate and inoculation does provide a pathway of many laboratory life forms capable of squeezing through the opening at the end of that needle.
No. No. And No. You are not going to get pneumonia from getting a flu or any other type of shot, and not from laboratory life forms whatever that is supposed to mean.
The subject of all the pity generated by the designing press should have stayed in mexico. As eastexsteve mentions, The only way to not get the flu is to not ingest the virus into your system. Her lifestyle as the article indicates opened her to many opportunities of life destroying pneumonia, not just the flu. To me, she's just another example of culture clash. Except in her case, she's the one that paid dearly.
Neither you nor I know if she was a natural born American citizen or was an illegal alien or legal resident alien. For what it is worth however, just because she had a Mexican name doesnt mean she was a wetback. There are many Americans citizens of Mexican descent living in the SW who have been American citizens for many, many generations and many longer than a lot of my family who came to the US in the late 1800s and early 1900s from Wales and Germany. And FWIW my father was born in Norway in 1921 and came to the US as a young child and later served in the US Army during WWII even as he wasnt yet a naturalized citizen.
Hell in the neighborhood where I grew up in in Baltimore had a large Polish population. Lots of people with Polish surnames, some whose families immigrated in the late 1900s but some who have been here since before the American Revolution.
And I dont see anything in the article that would indicate that her lifestyle was in any way to blame for her illness, unless you have information about this woman that the rest of us dont. Yes, she was a single mom of two young kids but she also worked a full time job, sometimes working 6 days a week.
But would you not agree that sanitary hygiene and western civilizations general understanding of how diseases can be controlled and even manipulated has come a long way since then?
Better sanitation and understanding how diseases are transmitted certainly has progressed greatly since then as have the success of vaccination programs. However better sanitation as in modern sanitation systems doesnt prevent the spread of influenza. Although frequent hand washing helps.
Bless you.
