The Economic Survey has warned that the new restrictions introduced across the globe due to the spread of the Omicron variant of coronavirus pose a threat to tourism as well as domestic passenger traffic in the near term."The trajectory of the tourism sector, especially international
tourism, remains uncertain,'' said the Economic Survey. ''The emergence of the Omicron variant and the consequential travel restrictions pose a threat to domestic passenger traffic in the near term,'' it added.
The travel restrictions in the early half of 2020-21 had halted the movement of Indian airlines and railways leading to a sharp fall in air and rail passenger traffic, noted the Economic Survey.
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.
