Nasal Vaccine Produces Successful Result in Mice – Somag News
It was observed that the nasal vaccine developed against Covid-19 prevented infection in mice as part of the study conducted by scientists at the Washington University School of Medicine. In the next stage, it is aimed to test the vaccine first on monkeys and then on humans.
The new type of coronavirus, which has spread all over the world and has become a pandemic, continues to negatively affect life in many regions. While the epidemic continues to spread day by day, studies for the vaccine that can counter the virus continue all over the world. Finally, scientists from Washington University School of Medicine tested the nasal vaccine developed on mice.
As part of the vaccine study, details of which were published in Cell magazine, the team placed the pointed protein, which Covid-19 used to capture cells for the vaccine, into the adenovirus, known to cause upper respiratory infections, and changed the adenovirus in a way that would not make it sick.
The adenovirus, which was rendered harmless after the procedures, carried the pointed protein into the nose, allowing the body to develop an immune defense against the new type of coronavirus.
The nasal vaccine had positive results on mice:
The developed vaccine was administered to mice in the laboratory environment by nasal and intramuscular injections. Immune response that prevented pneumonia was obtained in the vaccination by injection, but the infection could not be prevented in the nose and lungs. On the other hand, it was observed that one dose of nasal vaccine prevented infection in both the lower and upper respiratory tract.
Stating that they were surprised and happy when they saw a strong immune response in the cells of the inner wall of the nose and upper respiratory tract, team leader Michael S. Diamond said, “These mice were well protected from the disease. In some mice, we saw evidence of sterilizing immunity with no signs of infection after challenging the virus,” said team leader Michael S. Diamond.
Diamond added that they will begin studies to test the nasal vaccine first on monkeys after mice and then on humans as quickly as possible.

Alberta Health Services (AHS) has confirmed a case of measles in Edmonton, and is advising the public that the individual was out in public while infectious.
Measles is an extremely contagious disease that is spread easily through the air, and can only be prevented through immunization.
AHS says individuals who were in the following locations during the specified dates and times, may have been exposed to measles.
- April 16
- Edmonton International Airport, international arrivals and baggage claim area — between 3:20 p.m. and 6 p.m.
- April 20
- Stollery Children’s Hospital Emergency Department — between 5 a.m. to 3 p.m.
- April 22
- 66th Medical Clinic (13635 66 St NW Edmonton) — between 12:15 p.m. to 3:30 p.m.
- Pharmacy 66 (13637 66 St NW Edmonton) — between 12:15 p.m. to 3:30 p.m.
- April 23
- Stollery Children’s Hospital Emergency Department — between 4:40 a.m. to 9:33 a.m.
AHS says anyone who attended those locations during those times is at risk of developing measles if they’ve not had two documented doses of measles-containing vaccine.
Those who have not had two doses, who are pregnant, under one year of age, or have a weakened immune system are at greatest risk of getting measles and should contact Health Link at 1-877-720-0707.
Symptoms
Symptoms of measles include a fever of 38.3° C or higher, cough, runny nose, and/or red eyes, a red blotchy rash that appears three to seven days after fever starts, beginning behind the ears and on the face and spreading down the body and then to the arms and legs.
If you have any of these symptoms stay home and call Health Link.
In Alberta, measles vaccine is offered, free of charge, through Alberta’s publicly funded immunization program. Children in Alberta typically receive their first dose of measles vaccine at 12 months of age, and their second dose at 18 months of age.
