Close to a dozen DNA vaccines against COVID-19 are in clinical trials globally, and at least as many again are in earlier stages of development. DNA vaccines are also being developed for many other diseases. 'If DNA vaccines prove to be successful, this is really the future of vaccinology' because they are easy to manufacture, says Shahid Jameel, a virologist at Ashoka University in Sonipat, India. The urgency of combating COVID-19 has fast-tracked the development of vaccines that use genetic technology, such as messenger RNA and DNA vaccines, says David Weiner, director of the Vaccine & Immunotherapy Center at the Wistar Institute in Philadelphia, Pennsylvania. RNA vaccines were quicker to show strong immune responses in clinical trials; they have now been delivered to hundreds of millions of people around the world. But DNA vaccines have a number of benefits, because they are easy to produce and the finished products are more stable than mRNA vaccines, which typically require storage at very low temperatures.
