The “Covid-19” injection, made by the German biopharmaceutical company CureVac, showed complete protection against the Corona virus variant in South Africa, according to the results of a study conducted on mice.
The researchers said that the mice infected with the “Covid” virus, which were vaccinated, showed “strong antibody responses” and developed complete protection against the virus, with a survival rate of 100%.
The animals were deliberately exposed to the “Covid” strain B.1.351 – known as the South African variant – in addition to the original form of the virus as part of the preclinical infection study.
German researchers gave mice two doses of the CureVac vaccine based on mRNA, a difference of 28 days, and found that it was “effective” to prevent and reduce the reproduction of the virus in animals.
The study, which was published in a pre-print format, used ACE2 transgenic mice, which are common in Covid-19 vaccine research because they show similar responses to humans when infected with the virus.
CureVac’s chief scientific officer, Igor Splausky, said the risk of infection with coronavirus variants such as B.1.351, poses a major threat to global immunization efforts.
“As far as we know, this is the first study to challenge a genetically modified mouse model of a serious disease that shows complete protection against one of the most threatening viruses,” he said.
