> The other issue is that like other vaccine skeptics if you have a particular issue with mRNA (which doesn’t make sense given you don’t know anything about vaccines, or the differences between mRNA vaccines or other vaccines or even how vaccines work) you could have taken a non-mRNA vaccine. The J&J vaccine was pulled pretty early due to the clotting issues and AZ was not available in the US. It was puzzling to me early on why they'd make a vaccine with a single protein (the case with both mRNA and viral vector vaccine). It seemed obvious a whole virus would have many more opportunities for your body to generate an immune response. Even more puzzling is why China and other countries haven't adopted mRNA vaccines. |

Why do you find this puzzling? What countries haven’t adopted mRNA vaccines and what do you mean by “adopted”?

And Johnson&Johnson is still available now in the US. They pulled it out of an abundance of caution and because there were other vaccines on the market. If Johnson & Johnson was the only vaccine on the market it wouldn’t have been pulled because of the risk of clotting.
-edit-
This also doesn’t take into account risk analysis. Extreme likelihood of contracting a highly contagious disease with unknown severity and unknown long-term effects versus the unlikelihood of a blood cloth from Johnson & Johnson’s COVID-19 vaccine. Obviously any casual analysis would show that you’d get the vaccine.

Why would this be puzzling? Can you share some scientific resources that describe the differences in using a “whole virus” versus “part of a virus” and how that affects vaccine effectiveness? I’d like to read the same materials you did.
