The unprecedented onset of COVID-19 brought an unexpected storm in the lives of people all around the globe. The pandemic not only affected the jobs and social life of the people but also took a great toll on the lives of people, resulting in the death of lakhs of people in India.

Medical researchers around the world extensively worked for developing vaccines for the deadly coronavirus. India at present produces two locally developed vaccines for coronavirus: Covaxin and Covishield.

Covaxin is a product of Bharat Biotech, while Covishield is a product of Serum Institute of India. Both vaccines require two doses.

The government of India further approved for the use of Sputnik V vaccine, supplied by Russia. Unlike Covaxin and Covishield, the Sputnik V vaccine is a single dose vaccine. This vaccine is also locally being produced for fastening the vaccination drive.

Now, a new vaccine is in the process of developing- the nasal vaccine.

Prime Minister Narendra Modi on 07th June 2021, Monday said that researchers are working on the nasal vaccine, and hopefully it would turn out to be successful, which would further increase the pace of vaccination drive in the country.

What is a Nasal Vaccine?

As the name suggests, the nasal vaccine is a vaccine given through a person’s nose. It does not require to be injected in the body by a needle unlike the existing vaccines. It is a spray that is pumped via nostrils which would travel through the nasal passage and directly work upon the microbes that might have travelled through air.

As it is found out that the coronavirus commonly enters the body through the nose affecting the respiratory tract and lungs, damaging the respiratory system. The nasal vaccine would intercept the virus, helping combat the virus and prevent it from multiplication. It would also build a much widespread immune system against the coronavirus.

Currently, vaccination drive is going on for the people above the age of 18 years. The children below the age of 18 years are still left to be vaccinated. Which again is a matter of great concern as the old aged and the children are more vulnerable to coronavirus. The existing vaccines are not suitable for the children and hence the kids are left to be vaccinated.

Experts say, if the nasal vaccine turns out to successful, it would be safe to use nasal vaccine on children. It would also much easy to be administered in kids as it would not require insertion of needle on the skin, which children often resists because of the pain caused.

The nasal vaccine would be a single dose requirement unlike the existing vaccines. It is also expected to have no after affects like pain, fever or cold, as with the existing vaccines. The nasal vaccine could be self-administered with any medical help as it has a simple process of spraying the vaccine into the nostrils.

The self-assistance aspect of nasal vaccine would also reduce the crowd which is often seen for getting the present vaccines because of the que people have to stand in.
