MRNA vaccines are a promising approach as the production process is simple safety profiles are better than those. In recent years great progress has been made into mRNA vaccine development especially in individualized tumor vaccines. Injected into a muscle vaccine molecules stay around for a while and immune cells can easily find them.

Needle-free delivery of vaccines should not only increase compliance but should also prove to be a safer and less traumatic method of vaccine delivery. For some vaccines a different delivery method is better. Other options are a shot under the skin subcutaneous a spray into the nose drops that are swallowed and more.
