Research: Nasal vaccine is 100 percent effective

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.

Many pharmaceutical companies, including Bharat Biotech and Canada-based Senotize, are trialling nasal vaccines.

In addition, Russia has tested the nasal spray version of the Kovid-19 vaccine.
