According to the report of Financial Express, research on animals has found that, unlike single-dose and traditional vaccines, the Kovid-19 vaccine, which is taken through the nose by spray, has 100 percent effectiveness in terms of immunity and spread.
Researchers found that a single dose of the nasal vaccine provided 100 percent efficacy against Kovid-19 in mice and prevented the transmission of the virus from animal to animal.
The findings of the research, led by a joint team from the universities of Georgia and Iowa, were published in the journal Science Advances.
The fact that the vaccine, which is administered only as a single dose, can be stored at normal refrigerator temperature for up to 3 months is considered as a great improvement in storage.
On the other hand, administering the vaccine through the nose makes vaccination more reasonable, especially for people with a fear of needles.
The study concluded that the vaccine was successful in generating cellular immunity and regional immunity involving antibodies.
