DMRC Managing Director Vikas Kumar on Wednesday travelled by metro in the Blue Line to take stock of overall compliance of Covid-appropriate behaviour by passengers, officials said.
He travelled from Barakhamba to R K Ashram and got down at all stations, including the busy Rajiv Chowk, and then travelled back on it, a senior official said.
Blue Line connects Dwarka Sector 21 in Delhi and Electronic City in Noida.
“Shri Vikas Kumar, MD/DMRC today travelled on the Blue Line to take stock of the overall compliance to Covid appropriate behaviour by passengers while travelling. He also inspected stations including Rajiv Chowk interchange. Covid protocols were being followed by the passengers,” the Delhi Metro Rail Corporation tweeted.
The Delhi government on April 22 had made masks mandatory at public places again with immediate effect, and imposed a fine of Rs 500 for any violation amid a rise in coronavirus cases.
Frequently Asked Questions
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.
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.
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.
