Union Health Minister unveils world’s first intranasal COVID19 vaccine, iNNCOVACC

Union Health Minister Dr. Mansukh Mandaviya on 26 January unveiled world’s first intranasal COVID-19 vaccine, iNNCOVACC in New Delhi.

An overview of the news

  • The vaccine was launched in the presence of Dr. Jitendra Singh, Union Minister of State for Science and Technology (Independent Charge).

  • It is developed by Bharat Biotech International Limited (BBIL) in collaboration with Biotechnology Industry Research Assistance (BIRAC).

  • An initial manufacturing capacity of several million doses per year of the vaccine has been established, to be scaled up to one billion doses as needed.

  • iNCOVACC has been priced at Rs 325 per dose.

  • On September 9, 2022, Bharat Biotech's iNCOVACC, the world's first nasal COVID-19 vaccine, was approved for emergency use in adults.

  • On November 28, 2022, Bharat Biotech announced that the vaccine has been approved for restricted emergency use in adults.

About iNCOVACC Vaccine

  • Bharat Biotech's intranasal COVID-19 vaccine is a recombinant replicating adenovirus vectored vaccine.

  • A recombinant vaccine means that it has been manufactured using bacterial cells or yeast cells or parts of a virus to introduce viral proteins into the host.

  • It removes critical parts of the genome of SARS-CoV-2, so that the viral vector can no longer replicate.

  • Phase I, II and III clinical trials of the vaccine have yielded successful results.

  • The vaccine will be given intranasally through drops in the nose, a system that has been designed and developed to be cost-effective in low- and middle-income countries.

  • The maximum temperature range for storage and distribution of iNCOVACC is two to eight degrees Celsius.

Working of iNCOVACC

  • An intranasal vaccine stimulates a broad immune response by producing a wide range of antibodies including neutralising Immunoglobulin G (IgG) and mucosal Immunoglobulin A (IgA). 

  • The vaccine also initiates T cell responses. 

  • When the iNCOVACC vaccine is given to an individual, the immune cells in the body express the immobilized spike protein.

  • As a result, the body starts producing antibodies against the spike protein of SARS-CoV-2.

  • After a person is exposed to SARS-CoV-2, the immune system will block Covid-19 infection in both the upper and lower respiratory tract due to the presence of antibodies.

  • Therefore, iNCOVACC has the potential to block SARS-CoV-2 and prevent the transmission of Covid-19.

  • LHS 475b

  • It is roughly the same size as Earth, with a diameter of 99% that of Earth.

  • It is a celestial, rocky planet located approximately 41 light-years away from Earth in the constellation Octane.

  • It differs from Earth in two respects, first that it completes one orbit in only two days and secondly it is hundreds of degrees hotter than Earth.

  • It is closer to Earth than any other planet in our solar system.

  • It orbits very close to a red dwarf star and completes a complete orbit in just two days.

  • Exoplanet:

  • Exoplanets are planets that orbit other stars and are away from our solar system. The first confirmation of the detection of an exoplanet was in the year 1992.

  • According to NASA, more than 5,000 exoplanets have been discovered so far.

  • Scientists believe that there are more planets than stars because at least one planet orbits each star.

  • Exoplanets come in different sizes. They can be large and gaseous like Jupiter and small and rocky like Earth. There is also variation in their temperature, which can range from extremely hot (Boiling Hot) to extremely cold (Freezing Cold).

What is Doppler Weather Radar?

  • It is a special type of radar that uses the Doppler effect to generate velocity data about objects at a distance.

  • It is designed to improve accuracy in long range weather forecasting and monitoring using a parabolic dish antenna and a foam sandwich spherical radome.

What is Radar (Radio Detection and Ranging)?

  • It is a device that uses electromagnetic waves in the microwave region to detect the location, height, intensity, and speed of moving and non-moving objects.

What is the Doppler effect?

  • It refers to the change in wave frequency during the relative motion between a wave source and its observer. 

  • It was discovered by Johann Doppler, who described it as a process of increasing or decreasing the luminosity of stars depending on the relative motion of the star.
