| New research: heat-resistant new crown vaccine formula is effective against mutant strains |
Xinhua News Agency, Canberra, July 16 (Reporter Yue Dongxing and Bai Xu) An international research team recently published a research report in the American Journal of Infectious Diseases.
Effectively fight against COVID-19 mutant strains
.
Researchers from the Commonwealth Scientific and Industrial Research Organization of Australia and the Indian Institute of Science have jointly designed a heat-resistant trimerized novel coronavirus receptor binding domain derivative
.
Animal experiments have shown that this new vaccine formula triggers a strong immune response in experimental mice, which can protect them from the new coronavirus infection, and the antibodies induced by the formula can also neutralize 4 mutant strains such as Delta and Alpha
Researchers said that most of the new crown vaccines need to be refrigerated to maintain their effectiveness.
For example, AstraZeneca vaccines need to be stored at 2 to 8 degrees Celsius, while Pfizer vaccines need to be specifically refrigerated at minus 70 degrees Celsius
.
The new vaccine formula is heat-resistant and can be used in remote and high-temperature areas where the cold chain conditions of the vaccine cannot be provided
Next, the researchers will also prepare for the clinical trial of the formula vaccine, which is expected to be carried out in India later this year
Focus on the new crown pneumonia epidemic
