What are the 'four concerns you don't have to worry about' regarding the new corona vaccine?

The new coronavirus vaccine developed by Pfizer, BioNTech, and Moderna has already been vaccinated in the United States and Europe, and it is expected

that vaccination will begin in Japan with priority given to healthcare professionals from late February . On the other hand, various concerns about vaccines have been raised, and Associate Professor Archa Fox of the University of Western Australia explains 'four concerns that you do not have to worry about' regarding the new coronavirus vaccine.

The new coronavirus vaccine that has already been inoculated is an mRNA vaccine that uses messenger RNA that has information that can be translated into protein in the body. This is the first mRNA vaccine for humans, and some people have expressed the following concerns on SNS etc.

◆ 1: Isn't the vaccine entering people's DNA and changing the genome?
The genome is the genetic information required for cells to function and is stored on DNA in humans. Because RNA and DNA are different types of molecules, it is not possible for RNA to become part of the genome when vaccinated with the mRNA.

Mr. Fox explained the reason why the concern that 'inoculation with mRNA vaccine may rewrite the genome?' Was raised by synthesizing DNA from his own RNA using reverse transcriptase and incorporating it into the DNA of the host cell. He pointed out that the proliferating retrovirus may have originated. It is true that retroviruses can insert their own RNA information into the DNA of host cells, but since the new coronavirus is not a retrovirus and the new coronavirus vaccine is a virus-free vaccine, DNA cannot be rewritten. There is none.

◆ 2: Isn't the human body connected to the Internet by vaccination?
The mRNA contained in the vaccine developed by Pfizer, BioNTech, and Moderna is coated with lipid droplets, which makes it easier for the mRNA to enter cells. Meanwhile, some companies developing RNA vaccines are looking for ways to slowly disperse the vaccine in cells by wrapping it in hydrogel .

One conspiracy theory is that 'hydrogels have been used to create electronic implants that connect the human body to the Internet,' which is linked to the mRNA vaccine and 'vaccination connects the human body to the Internet.' The theory was born. The existing mRNA vaccine does not use hydrogel, and even if hydrogel is used, there is no danger that the human body will be connected to the Internet by vaccination.

◆ 3: Does vaccination cause autoimmune diseases?
Autoimmune diseases such as arthritis and multiple sclerosis are chronic diseases in which the immune system attacks its cells. Fox points out that there is no evidence that mRNA vaccines can cause autoimmune diseases, and that mRNA is so short-lived in the cell that it is unlikely to cause a chronic autoimmune response. In addition, contrary to the concern that 'inoculation of mRNA vaccine may cause autoimmune disease', mRNA vaccine is

seen as a promising method for treating autoimmune disease.

◆ 4: Isn't vaccination causing infertility?
On Twitter, the theory that 'antibodies to the new coronaviruscross-react and the immune system attacks proteins in the placenta and becomes infertile' is being discussed. The basis for this theory is that the spike protein targeted by the new coronavirus vaccine and the syncytin-1 protein found in the human placenta have similar amino acid sequences.

However, the similar region between the spike protein of the new coronavirus and syncitin-1 is very short, and it seems that it is equivalent to 3 to 4 amino acids at most, and the human immune system ignores this degree of similarity. Fox pointed out that if syncytin-1 cross-reacts with the new coronavirus peplomer, many women will become infertile simply by being infected with the various cold- causing viruses.

The immunity obtained by vaccination with the new coronavirus vaccine is expected to last for at least 8 months , and Moderna has developed a corresponding vaccine for British variants that may have high infectivity and lethality. I have announced that .

Vaccination is very important for many people, as some studies have shown that coronavirus infections reduce life expectancy in the United States by more than a year.

Research results show that the average life expectancy in the United States will be shortened by more than a year due to the influence of the new corona --GIGAZINE
