The Chinese vaccine is not authorized in the US. Neither is the Atrazeneca, out of the UK and heavily used elsewhere. Both use the traditional vector.
The J&J vaccine uses the traditional vector, and is authorized for use in the US, and has been for months, with widespread news coverage. If the messenger RNA is a problem, get the J&J.
Actually the J&J and AstraZeneca are not traditional vaccines. They work on the same basic principle as Pfizer and Moderna except they use an adenovirus as the vector. They still “trick” your cells into producing the virus proteins.

The J&J is much more like traditional gene therapy than the mRNA vaccines as it’s delivered precisely the same way.
Both instruct cellular production of the targeted spike protein. The viral vector J&J by delivering DNA instructions straight to the cell nucleus to create the RNA instructions for the cytoplasm to produce the spike protein. mRNA skips that step entirely staying out of the nucleus.
