Example:

> A principal benefit of the nucleic-acid-based approach to limiting the spread of infection is that genetic constructs introduced into the body would process quickly and not integrate into an individual’s genome. Similarly, the antibodies produced in response to treatment would only be present in the body for weeks to months. This is consistent with DARPA's intent to safely deliver transient immunity, halting the spread of disease by creating a firewall, and buying time for longer-term medical responses to be developed and deployed.
