Nasal vaccines are the most accurate way to keep the COVID-19 infection at bay. It’s a way to boost immunity where the virus actually enters the body.
It has been found that nasal vaccines are far more effective to fight against COVID-19 infection. It’s because scientists believe vaccination given through nose will be more effective as compared to vaccine shots given intramuscularly.
At this time, most nasal vaccines are under the state of development mode. They are likely to be given as a booster dose.

Working of Traditional Vaccines
Currently, the masses are being vaccinated via intramuscular mode where the injection is given in the arm. The effect of the vaccine is such that it helps building up of antibodies.
The formation of antibodies then move to different body parts and due to this, such vaccines are found effective in fighting severe infection.
But these vaccines are failing against the sub variants of Omicron as the person has a chance to get re-infection.
It certainly induces the production of antibodies in the mucosal tissue which is the inner lining of the mouth, throat and nose. It’s the area from where the virus enters the body.
Working of Nasal Vaccines
Nasal vaccines are the most accurate way to keep the COVID-19 infection at bay. It’s a way to boost immunity where the virus actually enters the body.
When vaccines are given through the nasal path, it only only ensures the prevention of infection through the production of antibodies but also entering the body in the first place.
Most experts now believe that it could also help in the prevention of long COVID. It can also help to curb the transmission of coronavirus.
Core Benefits of Intranasal Vaccine
In order to fight COVID-19 infection, vaccination through the nasal route has been found most effective.
Another reason why it is recommended is because it is needle-free and non invasive which can be easily administered.
Nasal Vaccines Under Development
Currently, they are in the developmental stage in the US. Right now, there are two approaches of its development.
One is the production of a protein based nasal spray and the other one is the mRNA vaccine which is usually delivered into the nose.
Still A Long Way to Go
Although, it’s known that nasal vaccines can be more effective in combating the COVID-19 transmission, it will still take time to precisely develop such vaccines which are effective in eliminating the infection.
One crucial aspect is that nasal vaccines can always provide a stronger immunity to prevent the virus from infecting.
Another reason why nasal vaccines can prove a boon to handle the menace is to fight sub variants that pose an increased risk of infecting the masses.
