Worldwide COVID-19 death toll tops a staggering 3 million

Worldwide, deaths are on the rise again, running at around 12,000 per day on average, and new cases are climbing too, eclipsing 700,000 a day.

The global death toll from the coronavirus topped a staggering 3 million people Saturday amid repeated setbacks in the worldwide vaccination campaign and a deepening crisis in places such as Brazil, India and France.

The number of lives lost, as compiled by Johns Hopkins University, is about equal to the population of Kyiv, Ukraine; Caracas, Venezuela; or metropolitan Lisbon, Portugal. It is bigger than Chicago (2.7 million) and equivalent to Philadelphia and Dallas combined.

And the true number is believed to be significantly higher because of possible government concealment and the many cases overlooked in the early stages of the outbreak that began in Wuhan, China, at the end of 2019.

When the world back in January passed the bleak threshold of 2 million deaths, immunization drives had just started in Europe and the United States. Today, they are underway in more than 190 countries, though progress in bringing the virus under control varies widely.

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.
