On par in what what? Should someone expect them to be less effective as a first shot? If done two has a different vector, what makes the two shots less effective? Would a AZ followed by a JJ work as well as two mrna? Theres a certain level of "we dont have data to prove it" but that isnt the same thing as "we expect this to be less effective." If the specific protein creates less immunity, or towards a variant, they do have time to modify it as well. There is a difference between the technology being inferior, and this implementation being inferior. It's bad faith to downplay the benefits of viral vector shots, with regard to logistics and handling.
