I'm definitely over 60. I could have got the Astrazeneca vaccine last week here in Sibulan, but passed. Both the J&J and the AZ are viral vectors that pierce the cell nucleus and deposit DNA. The Sinovac actually uses "deactivated" corona virus, and it's now being shown that the spikes themselves are actually highly toxic and can damage organs and can cross the blood brain barrier. I wouldn't take any of those and am holding out for eventual availability of Pfizer or Moderna. In my very humble opinion I think the new mRNA technology is the way to go for the highest safety and effectiveness.
Not sure what you are asking for a source on? I assume you must understand already how the DNA viral vectors of AZ and Sinovac work, so you must be asking for sources on the other items. There is so much published information on this now, a request for sources is a bit surprising. But, here are a few: https://www.biorxiv.org/content/10.1101/2021.01.11.425914v1.full https://scitechdaily.com/covid-19-i...-attacks-vascular-system-on-a-cellular-level/ https://www.pnas.org/content/117/41/25254 https://www.technologynetworks.com/...vidence-that-covid-19-enters-the-brain-344136

Here's answers on the spike protein: https://blogs.sciencemag.org/pipeline/archives/2021/05/04/spike-protein-behavior
I agree the new mRNA is best, but I'm a realist, and it's very likely I won't be able to get either one here. After my AZ is done, or if it's ever done, I'll look for one for a boost. Right now best would be to find one near the end of July and I'd mix n match.
Your post was reported as misinformation by a user. I didn't really see anything wrong with it myself. Now that the sources are out there perhaps the user that reported it can inform us on what the objection to the content was.
The comments in that paper relate to the mRNA vaccines. Those vaccines do not generate free intact spike proteins in the body. But, the sinovac uses a deactivated actual corona virus as the carrier of the DNA strand. That vaccine was developed at a time when they were not aware of the toxicity of the spike protein by itself. The argument for sinovac is that the studies that found virus protein toxicity exposed animal subjects to much higher concentration levels that what is in the vaccine. Still, as long as there are other options available I would prefer to not inject actual covid spike proteins at any level.
