With AstraZeneca's announcement today of positive high-level results from an interim analysis of clinical trials of their vaccine candidate AZD1222, I felt compelled to post the picture above that highlights the differences between vaccines and antibody therapy.

This may lead to confusion when discussing them on this forum so it will be important to specify which AstraZeneca product is being discussed.
I've added just a few of the antibody therapy and vaccine candidates to the figure. There are plenty more in the pipeline around the world!
