Nepal requests India to fast-track shipment of 10 lakh Covishield doses already paid for

As a deadly second wave of COVID-19 continues, Nepal has also requested ventilators, oxygen cylinders and medical supplies from India. Though Nepal has approved a Chinese vaccine, it is not recognised by the WHO and there are concerns over its safety and efficacy.

Nepal has requested India to fast-track the Covishield vaccine consignment it has already paid for, sources say. With new cases exploding over the past one week, Nepal has also requested crucial medical supplies, including ventilators, and a steady flow of oxygen from India.

COVID-19 cases are rising in the Himalayan nation after a double mutant variant of the virus which originated from India travelled across the porous border.

On February 20, Nepal received the first commercial shipment of 10 lakh doses of Covishield from the Serum Institute of India (SII). Sources say that an equal amount of doses is pending with SII and the country is not sure when it will receive it.

"This has held up vaccination of the critical segments of the population such as senior citizens and frontline workers," a diplomatic source 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.
