Research by the Japanese medical community has found that the neutralizing antibodies produced by the human body through vaccination with COVID-19 vaccines have only about 1/7 of the protection against Mu mutants compared to the original strain. But experts also say that vaccination still has advantages and is not completely ineffective.
The COVID-19 Mu variant was first discovered in Colombia, South America, and Japan has confirmed two cases in airport quarantine since June this year.
Japan’s TBS TV station reported that a research team composed of Associate Professor Sato Yoshi from the Institute of Medical Sciences of the University of Tokyo, Japan, and others, found that compared with the original virus strain, the protective power of the antibody against Mu variant is only about 1/7, when they studied the neutralizing antibody that inhibits the activity of the virus through vaccination.
But Sato also emphasized that in addition to triggering neutralizing antibodies, vaccines can also improve “immune system memory” and “cellular immunity”, so it’s not that vaccination is completely useless.
