Shares of Hindustan Aeronautics Limited (HAL) rose over 2 percent on September 7 after the company said it assembled and tested gas turbines that were used in recently commissioned aircraft carrier, IAC-1 Vikrant.

“HAL is proud to be associated with India's first indigenously designed and built aircraft carrier, IAC-1 Vikrant which was commissioned recently as INS Vikrant by the Prime Minister at Kochi,” the company said in an exchange filing. “IAC is powered by four General Electric LM2500 Gas Turbines supplied by HAL.”

According to the company these gas turbines were assembled and tested at HAL's dedicated facility at Bangalore.

“HAL carried out critical activities towards readiness of IAC for basin trials. HAL's team was actively involved in the integration of the power plant to the IAC and was onboard IAC for all sea trials in the absence of foreign OEM representatives contributing substantially to the Make-in-India concept,” Hindustan Aeronautics said.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
