Don't want to be an alarmist here, but the two vaccines
getting great results and early approval are a different
technology. Both Pfizer and Moderna force the body to
reproduce the virus protein itself, and then the immune system
responds. The Oxford/AstraZeneca vaccine will be more conventional.
While still focusing on the capsule protein, the vector itself is a modified
chimpanzee virus. This might be why they can control the dose given
better.
RNA-messenger vaccines have only been used on animals to date, out of
fear that the genetic material would be incorporated into that of the
host. This does not seem to have happened so far.
