Techniques in Infectious Diseases International Publisher of Science, Technology and Medicine Is The Time Coming for Plant- Made Vaccines?

Vaccines have significantly improved human health since their introduction in the last century. They are the most potential weapons to fight the majority of infectious diseases, which are responsible of more than 45 % of the total deaths in developing countries [1]. Traditional vaccines are made of a live attenuated or killed pathogen, and either injected or given orally. There are other two categories of vaccines, subunit vaccines and nucleic acid vaccines, being the choice of producing one of them related to factors such as pathogenesis, immunobiology, and epidemiology of the disease [2]. The considerable extension in time of the vaccine production process, its high cost, the stringent conservation conditions required, the need to provide immunization to a high world population with marked differences in packaging, storage, and delivery capacities, and the emerging and re-emerging outbreaks needing a fast response from the pharmaceutical industry have triggered the search for ne
