The psychological effect of aerospace, marine and submarine long-term missions

Background: Vaccination is one of the most efficient ways of prevention and immunization against infectious agents. This article aimed to review the importance of recombinant vaccines for immunizing against biological agents in army forcesMaterials and methods: This study was performed by searching through the internal and external websites and textbooks of military medicinesResults: Killed or attenuated pathogens and inactivated toxins all are normally used for vaccination. But some complications have been seen due to existence of different antigens in their compound. On the other hand there are many newfound infectious agents we don rsquo;t have any efficient vaccine for them. For this reason it rsquo;s necessary to utilize the new technologies for recombinant vaccines.Conclusion: Various applications of recombinant vaccines not only in public health but also in military medicine play an important roles and development in this field can cause a great prosperity in personnel rsquo;s health status.
