Can I give my cat her vaccine orally instead of intra-nasally as directed?

She sneezed out all of the last one I gave her 2 weeks ago. I used to have a really big dog kennel business but caring for cats is alot different. My old Himalayan didnt sneeze or react at all when he got his intra nasal vaccine. I have to save money by giving my own vaccines and they dont sell the shots anymore. Anyone know if I can give it orally ? Its going to the same place after all..( nose vs. mouth)
