Israel's Defense Minister Naftali Bennett claimed on Monday that the country's Defense Biological Institute has made the coronavirus vaccine. He said that the institute has achieved great success in preparing antibodies to coronavirus. Defense Minister Bennett stated that the phase of development of the coronavirus vaccine is now complete and researchers are preparing for its patent and mass production.
However, on the other side, leading health experts have warned scientists may not be able to develop a vaccine against the coronavirus disease (Covid-19) at all and pointed that it has happened before in case of HIV and dengue among others, a report has said.
More than 100 vaccines are currently under pre-clinical trials and a couple of those have entered the human trial stage—at Oxford University in England made from a chimpanzee virus and in the US for a different vaccine produced by Moderna.
“There are some viruses that we still do not have vaccines against,” Dr David Nabarro, a professor of global health at Imperial College London, was quoted as saying by CNN on Sunday.
“We can’t make an absolute assumption that a vaccine will appear at all, or if it does appear, whether it will pass all the tests of efficacy and safety,” Nabarro, who also serves as a special envoy to the World Health Organization (WHO) on Covid-19, said.
Most experts are confident that a Covid-19 vaccine will eventually be developed because unlike previous diseases like HIV and malaria, the coronavirus does not mutate rapidly.
