Coronavirus pandemic| As schools shift classes online, a lot to learn and unlearn, for teachers, students & parents

Schools have tried to ensure that academic continuity is maintained through virtual classes, but technical glitches, unstructured lessons, lower engagement and connectivity issues are concerns.

Thirty-six-year-old Ravi Rajan’s two children have been attending classes over a virtual platform since March 30. The children, 11-year-old Sharan and six-year-old Tanvi are able to attend e-school only on alternate days. Reason? Rajan only has one laptop which is used for his office work as well. The result is that the children’s attendance will be impacted.

“These are not small sessions but regular school lessons from 8am to 2pm. We don’t have the infrastructure to enable both the children to attend e-school at the same time. Due to this, they will miss out on the classes and will find it tough to catch up when school reopens,” Rajan said.

Amidst the Coronavirus (COVID-19) outbreak that has led to a lockdown leading to schools temporarily shutting down, the new academic year has begun across these institutions on a digital mode. While some schools have begun full-fledged e-classes, the rest have sent assignments to be completed on the computer/laptop.

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.
