Answer 1

Right option is (d) Cost, transportation, storage

Explanation: The disadvantages of recombinant protein or polypeptide vaccines are: their cost is very high and often prohibitive since they are produced by either bacterial fermentation or in animal cell cultures. They have to be stored at low temperatures. This makes their storage and transportation problematic.
