Answer:
GMOs can be used to produce cheaper, easier to administer, and safer vaccines
Step-by-step explanation:
Genetically modified organisms (GMOs) are organisms whose genomes have been altered in the laboratory by using genome engineering techniques. These GMOs have a fundamental role in clinical research and they have been increasingly used in the last decades for developing safer and cheaper vaccines. For example, genetically engineered hepatitis B vaccines have been developed with recombinant DNA techniques using genetically modified yeast (Saccharomyces cerevisiae). Moreover, GMO plants are nowadays also being used to develop consumable vaccines which can be orally administered to be absorbed and assimilated through digestion.
