USC researchers announced Monday they’ve developed a new method to counter emergent mutations of the coronavirus and hasten vaccine development.<\/p>\n
Using artificial intelligence — A1 — the research team at the USC Viterbi School of Engineering developed a method to speed the analysis of vaccines and zero in on the best potential preventive medical therapy.<\/p>\n
The method is easily adaptable to analyze potential mutations of the virus, ensuring the best possible vaccines are quickly identified — solutions that give humans a big advantage over the evolving contagion, according to Paul Bogdan, associate professor of electrical and computer engineering at USC Viterbi and corresponding author of the study.\u00a0The machine-learning model can accomplish vaccine design cycles that once took months or years in a matter of seconds and minutes, Bogdan said.<\/p>\n
“This AI framework, applied to the specifics of this virus, can provide vaccine candidates within seconds and move them to clinical trials quickly to achieve preventive medical therapies without compromising safety,” he said. “Moreover, this can be adapted to help us stay ahead of the coronavirus as it mutates around the world.”<\/p>\n
When applied to SARS-CoV-2 — the virus that causes COVID-19 — the computer model quickly eliminated 95% of the compounds that could have possibly treated the pathogen and pinpointed the best options, according to the researchers, whose findings appear in Nature Research’s Scientific Reports.<\/p>\n
The AI-assisted method predicted 26 potential vaccines that would work against the coronavirus. From those, the scientists identified the best 11 from which to construct a multi-epitope vaccine, which can attack the spike proteins that the coronavirus uses to bind and penetrate a host cell.\u00a0Vaccines target the region — or epitope — of the contagion to disrupt the spike protein, neutralizing the ability of the virus to replicate.<\/p>\n
The engineers can construct a new multi-epitope vaccine for a new virus in less than a minute and validate its quality within an hour, according to Bogdan. By contrast, current processes to control the virus require growing the pathogen in the lab, deactivating it and injecting the virus that caused a disease. The process is time-consuming and takes more than one year.<\/p>\n
The method is especially useful during this stage of the pandemic as the coronavirus begins to mutate in populations around the world, according to USC. Some scientists are concerned that the mutations may minimize the effectiveness of vaccines by Pfizer and Moderna, which are now being distributed.<\/p>\n
Recent variants of the virus that have emerged in the United Kingdom, South Africa and Brazil seem to spread more easily, which scientists say will rapidly lead to many more cases, deaths and hospitalizations.<\/p>\n
Bogdan said that if SARS-CoV-2 becomes uncontrollable by current vaccines, or if new vaccines are needed to deal with other emerging viruses, then USC’s AI-assisted method can be used to design other preventive mechanisms quickly.<\/p>\n
For example, the USC scientists used only one B-cell epitope and one T- cell epitope, whereas applying a bigger dataset and more possible combinations can develop a more comprehensive and quicker vaccine design tool. The study estimates the method can perform accurate predictions with over 700,000 different proteins in the dataset.<\/p>\n
