US pharmaceutical company Modena announced the results of a study on the 25th (local time) that its novel coronavirus infection (Corona 19) vaccine can also be effective for mutant viruses. However, the immune effect against the mutant virus, which was first discovered in South Africa, was relatively low, and additional clinical trials were started to improve it.
According to Reuters and AFP News, Modena announced that it will begin clinical trial research on the South African mutant virus. This is an experiment to find a way to enhance the immune effect of modder or vaccine against mutant viruses by increasing the number of vaccinations from two to three.
Stephen Bangsel Modena, CEO, said, “The latest research data has given us confidence that Modena vaccines are immune to the newly discovered mutant virus.” As a result of the study, the modal or vaccine immunity effect against the British mutant virus was not different from that of the existing Corona 19 virus.
However, in the case of the South African mutant virus, the amount of neutralizing antibodies that can prevent it has decreased to a sixth level. This means that the vaccine’s immune effect decreases. That’s why Moderna has been working on further work to enhance this effect. “We are conducting a clinical trial to introduce an additional’booster vaccine’ against the South African mutant virus,” said CEO Bangsell. It is explained that it will make a’booster vaccine’ that helps boost immunity against mutant viruses through additional vaccination after the first vaccination by appropriately modifying the existing vaccine.
Moderna plans to release the results of a study on mutations in South Africa and the United Kingdom conducted with the National Institutes of Health (NIH) in the near future so that the entire scientific community can analyze it.
