Israel, the world's earliest vaccinator, has reported that its effectiveness in preventing infection has dropped to about 60 percent in six months and 40 percent in seven months. There are also reports that 60% of inpatients in the country are vaccinated. As a result, the country has already started its third inoculation. However, "repeated immunity with the same antigen has resulted in an increase in the number of deaths in animal studies from the fifth time; nearly half of them die after 7 to 8 repetitions," says Yasufumi Murakami, professor emeritus
at Tokyo University of Science. Now that there are only "vaccines" other than lifestyle, "murak antibodies
(Mulak antibodies)" that are considered effective against multiple mutant strains have been developed and may be marketed in the near future. This "Mulac Antibody" is an antibody jointly developed by DD Supply Co., Ltd. and a research team led by Professor Emeritus Yasufumi Murakami (Ph.D. in Pharmacy, Graduate School of Pharmaceutical Sciences, The University of Tokyo) and Representative Director of Tailor-Made Medical Research. Last year, Professor Murakami's team began developing a new corona diagnostic kit in collaboration with Alfresa Pharma, and succeeded in creating a new coronavirus antigen rapid test kit to replace PCR testing. The kit was launched by the company in March this year with approval from the Ministry of Health, Labour and Welfare. It was widely reported that this inspection kit shortened the judgment, which had previously been 15 minutes, to 5 minutes. Delta strains, which are currently spreading worldwide, are likely to shift from conventional PCR methods to antigen rapid diagnostic methods because the amount of viruses produced by infected people is much higher than conventional (1,000 times that of conventional methods). In fact, it has been reported that the U.S. will stop diagnosing with PCR from 2022. Prof. Murakami's explanation at the media briefing held on September 9 will be introduced below. Prof. Murakami contributed to the "third and subsequent additional inoculations." See article 1 related article. ■ Delta "before" and "after" changed the world Until the emergence of delta strains, vaccines have certainly been the trump card for pandemic convergence. However, with the advent of Delta stock, things have changed. Research has found that delta strains have a powerful infection power of 1 to 8 people, and their ability to spread viral infections is equivalent, whether in inoculated or non-inoculated. Mutations occur randomly, but as vaccination progresses, vaccine-resistant mutant viruses are "selected". Viruses are largely grouped into DNA type and RNA type, but coronavirus is an RNA type virus. Dna-type viruses have a mechanism to correct dna replication errors that have resulted in the process of proliferation, so it can be said that there are fewer mutations in genes compared to RNA viruses.
