US Immigration from Philippines

We completed an approximately six year process from K1 -> AOS -> ROC -> Citizenship back in mid-August this year. I updated our timeline back then, but I just felt the need to log in and take a moment to give thanks, so:

Thank you so much to VisaJourney and its community! We seriously could not have done this without you.

This is quite possibly the most useful and active forum on the internet. Anytime we had a question, the answer could be found here and/or we could ask it ourselves and get a solid answer. Those answers always came back same day, if not within seconds or minutes from posting. Even the most obscure issues are solved here in a moments notice. You've helped us save thousands of dollars avoiding the use of an immigration lawyer, and rescued us from millions of headaches or bouts of anxiety. The knowledge here far exceeds anything that could've been paid for professionally, and all of it.. at no cost to us.

The end-result: I get to be together with my wife, every day, and for the rest of my life. Plus, she now has all of the same rights as any other American citizen, and soon... her passport will arrive in the mail and we can finally travel to places we've only ever dreamed of seeing.

I feel like the best way to continue giving thanks is to stick around and help other members of the community with the knowledge we've learned along the way from our experiences and from you.

Once again, and with the utmost appreciation and regard for all of you here, thank you! I wish you all the best in your own visa journey and in your lives moving forward beyond it.

Reading through --> USCIS Immigration Vaccination Requirements it lists 8 different vaccines, but when you look at the I-693 it has more on there. If I go to https://www.cdc.gov/vaccines/ link from the same instructions and answer the questions I just get MMR, TDap and the flu vaccines are needed.

I know she has to have documentation to show she got certain vaccines but what are all the vaccines that my wife will need before she is allowed to come here on her visa once we get it? I would like to get this taken care of now and make sure she is all set so we don't have to worry about it later.

So who do I follow? The requirements page here, the I-693, or the CDC?

Title says it all... When do I start the I-864? Do they tell you when to do it or do I just do it now? Can this be filed online as well, I can't seem to find it online only in PDF form?

I hope this is the correct forum for this post.

I reviewed some sites that said it was possible to submit a 13A visa application form on the Embassy to the Philippines site. My embassy would be the one located in Washington, DC. I see an Immigrant Visa form but very little instructions. On the Los Angeles Embassy site, they have an entire page with instructions specific to 13A. So my questions are:

1. Can you submit a 13A form in the US to a US Embassy (vs. having to be in the Philippines)?
2. Is there a reason why the Washington DC Embassy does not offer that information?

I've reached out to the embassy directly as well, but thought I would ask this audience, which always seems to have the answers.

Thanks so much for any help you can provide.
