Advancements in DNA vaccines against COVID-19
The coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continues to spread globally. The total number of infections has reached 109.88 million globally with 61.88 million reported as recovered.
The rapid spread of the pathogen and the increasing number of cases highlight the need for an effective and safe vaccine. As vaccination efforts roll out in many countries, new types of vaccines, like deoxyribonucleic acid (DNA) vaccines, are under research..
Researchers at the Department of Pharmacy, Pelotas, Rio Grande do Sul, in Brazil, explained the functionality and efficacy of DNA vaccines in pandemic scenarios. They also provided a summary of the DNA vaccines being tested in clinical trials.
