In the United States, an innovative vaccine has been developed that can protect against several coronaviruses at once, Medical Xpress reports.
Amesh Adala, Senior Research Fellow at Johns Hopkins Center for Health Security in Baltimore, recounts the study’s findings:
“Other coronaviruses cause about 25% of common colds and also pose a serious threat of emerging infectious diseases. The ability to eliminate coronaviruses as a biological threat would be a great advantage, and a generic vaccine would be the best tool for that. “
The cost of an experimental dose of a unique drug does not exceed $ 1, which is incomparable, for example, with the cost of Pfizer and Moderna vaccines, which are used in the United States. At the same time, its effectiveness has already shown itself. In animal studies, the vaccine coped well with two types of coronaviruses – SARS-CoV-2 and the one that causes epidemic diarrhea in pigs. She did not protect from the disease, but activated the immune system when infected and helped to avoid severe symptoms.
The principle of action of the new vaccine is based on its following part of the SARS-CoV-2 spike protein, a “viral fusion peptide” that is essentially universal among coronaviruses.
