DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

mRNA COVID-19 vaccines are highly effective among front liners, CDC study shows

The study, published in CDC's Morbidity and Mortality Weekly Report (MMWR), highlights the efficacy of mRNA vaccines in protecting against SARS-CoV-2 infection.
