Vaccine companies searching for 1-shot dose of COVID-19 vaccine.

New vaccine technologies are, however, being developed -- ones that only need one shot, but generate a sustained, yet controlled, immune response.

For example, the Arcturus vaccine developed by Payne and his colleagues uses a special technique. The vaccine contains a small piece of genetic material, which not only instructs the body to produce a protein that will trigger an immune response, but also adds an extra packet of instructions that effectively helps turbocharge the amount of protein produced.
