The World Health Organization chief on Wednesday said a nearly 90% drop in recent COVID-19 deaths globally compared to nine months ago provides “cause for optimism,” but still urged vigilance against the pandemic as variants continue to crop up.

Director-General Tedros Adhanom Ghebreyesus said that last week just over 9,400 deaths linked to the coronavirus were reported to the WHO. In February of this year, he said, weekly deaths had topped 75,000 globally.

“We have come a long way, and this is definitely cause for optimism. But we continue to call on all governments, communities and individuals to remain vigilant,” he said at a virtual news conference from the WHO's Geneva headquarters.

“Almost 10,000 deaths a week is 10,000 too many for a disease that can be prevented and treated.”

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.
