The outbreak of new pandemics all over the world has risen to a global scale, pushing the demand for efficacious vaccines to soar, thereby viral vector and mRNA technology-driven vaccines. Nevertheless, these shots display poor stability, which makes the cold-chain storage and transportation facilities a prerequisite. It is a very large challenge in low- and medium-income countries with irregular electricity supply. In this case, a very high percentage of vaccines are useless because of temperature changes and incorrect storage conditions, which is materialized by the money loss and imperfection of immunization. In order to solve these problems, freeze-drying has developed into a new approach to improve the stability of vaccines by depriving them of biological activity and thus extending their shelf life. This method provides a solution to degradation, pH shifts, freeze-thaw cycles, and so on, using stabilizers like sugars and polymers, which are the main stabilizers of the vaccine’s architecture during the lyophilization process. Additionally, the use of cryoprotectants protects the sensitive formulation of peptides and proteins. The upcoming technologies in vaccine development foresee the invention of thermostable freeze-dried vaccines that are cold-chain friendly, and thus, their transportation will be uncomplicated, ultimately enabling easier distribution and access. The road of vaccine production in combination with new delivery methods, such as microneedle patches, is anticipated to revamp vaccine accessibility and administration mechanics in autopiloted production lines. The universality of freeze-dried vaccines can be useful not only in the military but also in veterinary and biodefense fields; thus, the vaccines can counteract zoonotic diseases and bioterrorism. On the whole, the technical progress of vaccine freeze-drying provides immense possibilities for the improvement of global healthcare for infectious diseases and for the effectiveness of immunization strategies.
