Coronavirus lockdown: How can schools reopen safely? UN agencies, World Bank lay down guidelines

According to the guidelines framed by UNESCO, UNICEF, World Bank and the World Food Programme, the best interests of children and overall public health considerations, based on an assessment of the associated benefits and risks to education, public health and socio-economic factor, must be central to national and local authorities' decisions to reopen schools.

Warning that widespread closures of educational facilities present an unprecedented risk to children's education and well-being, the UN agencies have laid down guidelines for reopening of schools that have been closed in most parts of the world due to the COVID-19 outbreak.

According to the guidelines framed by UNESCO, UNICEF, World Bank and the World Food Programme, the best interests of children and overall public health considerations, based on an assessment of the associated benefits and risks to education, public health and socio-economic factor, must be central to national and local authorities' decisions to reopen schools.

The guidelines note that while there is not enough evidence yet to measure the impact of school closures on the disease transmission rates, the adverse effects of school closures on children's safety and learning are well documented. Gains made in increasing access to children's education in recent decades risk being lost and, in the worse cases, reversed completely.

As per UNESCO estimates, over 154 crore students are severely impacted by closure of educational institutions across the world amid the COVID-19 outbreak.

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.
