Metro rail systems are emerging from the pandemic’s shadows, but businesses face long Covid 

Ridership numbers in some metros are inching towards pre-pandemic levels, while others are still struggling from Covid-induced capacity restrictions as well as the WFH shift and passenger hesitancy. Non-fare revenue in most metros has also taken a hit

In Lucknow, FM radio channels have been airing an unusual advertisement, wooing passengers back to metro rail travel, over the last few months. Across the country, metro rail public transport systems had been hit badly by the COVID-19 pandemic.

Over the last few months, however, some metros have been emerging from the shadow of COVID-19. In September and October, Lucknow Metro and Chennai Metro ferried around 70 percent to 90 percent of the passengers they had carried during the pre-pandemic period.

But, the Delhi Metro and Bengaluru Metro are still emerging from the pandemic slump, with traffic levels still at half the numbers recorded in pre-pandemic times. This is partly because of pandemic triggered rules, including physical distancing norms affecting capacity utilisation, continuation of the work-from-home (WFH) model by many employers, and people preferring to use private vehicles due to the fear of coming into close contact with virus carriers.

Even those using public transport systems may be opting for open window modes such as buses or pooled cabs or private car pools with known people as the virus is known to be highly transmissible in closed spaces, feel experts.

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.
