What is the difference between the Corona Virus vaccine and the influenza vaccine? November 10, 21:01
Vaccines for the virus of respiratory infections are considered difficult to develop, and only influenza vaccines are currently put to practical use.
According to the Ministry of Health, Labour and Welfare, in the case of influenza vaccines, although there is no function to completely suppress the infection, it is that the effect of preventing the onset to some extent or be severe by inoculation can be expected.
A domestic study found that 34% to 55% of elderly people aged 65 and over had the effect of preventing 82% of deaths.
Some studies have also reduced the risk of vaccines in children under the age of six by about 60 percent.
Corona Virus Vaccines
On the other hand, vaccines for many new coronaviruses are being developed using completely different technologies than conventional influenza vaccines, so it is not known in detail how effective they can be expected.
Influenza vaccines are produced by chemical treatment to increase the actual virus and prevent it from infecting it.
Pfizer is developing a vaccine using a gene called “mRNA”.
By administering “mRNA” with information about the new coronavirus, it acts like a blueprint in the body, and it makes a part of the virus which becomes a mark of immunity.
According to Tetsuo Nakayama, a professor at Kitasato University who is familiar with vaccine development, this vaccine is administered by wrapped in a grain of lipids, which could lead to the production of antibodies more efficiently.
