An ideal vaccine should be safe, non-toxic, and capable of inducing long-lasting immunity with minimal side effects. It should also be affordable, easy to administer, and suitable for large-scale production. Edible vaccines align with these characteristics, offering a simplified vaccination process through oral delivery. They eliminate the need for needles, reduce costs associated with storage and transportation, and are easy to scale for mass production. Their ability to stimulate both systemic and mucosal immunity enhances their effectiveness against various diseases. By meeting these criteria, edible vaccines are poised to address global health challenges more efficiently than traditional methods.
