African trident bat (IMAGE) Johns Hopkins Medicine Caption A photo of an African trident bat, one of the species that harbors a coronavirus with a peptide (protein fragment) similar to one found on the spike protein of SARS-CoV-2, the cause of COVID-19. Johns Hopkins Medicine researchers have shown that people vaccinated against COVID-19 might also produce an immune response to such peptides on a number of bat coronaviruses, considered to be a prime threat for future “jumps” of animal-to-human viral diseases.
