Why is "durable resistance against mutations" so important? Creating such a vaccine can combat a large number of coronaviruses, including the coronavirus disease 2019 virus. The all-purpose vaccine is as eye-catching as the Holy Grail, especially now that the threat of new mutant strains in the world has overwhelmed the new crown vaccine arsenal.

Core Secret: Research on universal vaccines has had only limited success over the years, but they still attract new investment and interest from researchers. .

• The National Public Television of the United States once reported that the Warat Deli Army Research Institute is developing an all-in-one coronavirus vaccine that was in the phase 1 clinical trial phase in April.

• Fauci, director of the Institute of Infectious Diseases of America, said in a statement: "The scientific community is making progress in promoting global health."
