It has been two years since most of the world has been battling the deadly coronavirus pandemic. Cases have risen and fallen in countries but there is no indication yet that the infection will completely go away.

An exception is several pristine and remote islands that have managed to remained unaffected by coronavirus. The residents of those areas have nevertheless received vaccines against the infection.

Here is a list of countries/ territories that have zero COVID-19 cases, according to the World Health Organization:

Tuvalu: This island country in South Pacific comprises of nine thinly-populated islands. Nearly 50 people per 100 population have been fully-vaccinated against the coronavirus here.

The Federated States of Micronesia:  The country, spread across the Western Pacific, is made up of four island states. More than 38 people per hundred population in these islands are fully-vaccinated.

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.
