After Covaxin, India is going to get another indigenous vaccine soon. The government has also made an advance payment of 1500 crores to Hyderabad-based company Biologicals for the supply of its 30 crore doses. The Phase III trial of the 'Carbevax' vaccine is currently underway. This is the first corona vaccine made from spike protein which will be available at the cheapest prices in the country.
Know why the vaccine is important for the country and what is its specialty
CarboVax is a recombinant protein subunit vaccine. It is made of proteins found on the surface of the coronavirus. This spike protein is what helps the virus to enter the body's cells. After this, the virus starts spreading infection in the body by increasing its number.
Although it is not harmful if it just enters the body, our immune system starts developing antibodies considering it as a virus. Helps in preparing in this way, due to this our chances of falling seriously ill are greatly reduced.
Hepatitis B vaccine is made from this technology
For decades, this technology has been used to make hepatitis B vaccines. Carbavax will be the first vaccine to be made in this way. Novavax has also developed a protein-based vaccine, the use of which is awaiting approval.
low cost made
Vaccines that have been approved so far. They are based on mRNA (Pfizer, Moderna) viral vector (Covishield, Johnson & Johnson, Sputnik-V). or inactivated vaccines (Covaxin, Sinovac CoronaVac). Carbavax targets mRNA and only spike proteins like viral vaccines, but the approach is different. Two doses of Corbevax will also have to be given. Low-cost methods have been used to make it. Therefore it will be one of the cheapest vaccines.
