Coronavirus is a contagious respiratory illness that can be spread through droplets in the air, such as when an infected person coughs or sneezes.
It causes mild to severe symptoms and affects people of all ages.
Nasal sprays are a common treatment option for the common cold and help alleviate symptoms as well as reduce duration of illness.
How would it work as a vaccine?
Nasal sprays are often used to help relieve the symptoms of a cold, such as, sore throat, fever, and congestion. They contain medication that is inhaled through your nose.
The medicine in the spray helps reduce inflammation in your sinuses. Reducing inflammation can help alleviate some of the pain caused by a cold or flu virus.
Medicine in the nasal spray is able to kill the virus before it can cross into other areas of the respiratory system.
A nasal spray blocks the entry of viruses, stopping them from proliferating in the nasal cavity, which reduces their load.
So, if you contract a virus, it will lower the amount of the virus in your body. This makes you less likely to infect others and helps slow its spread.
On the other hand, if you have not contracted the disease, a nasal spray meant to kill the virus may act as a form of chemical protection.
