The number of new coronavirus cases and deaths reported globally fell everywhere except the Middle East and Southeast Asia last week, according to a World Health Organization weekly report released Wednesday.

In its latest weekly update on the pandemic, the U.N. health agency said confirmed cases dropped 12% to more than 3 million and reported deaths declined 22% to about 7,600.

WHO Director-General Tedros Adhanom Ghebreyesus described the continuing decline of COVID-19, which peaked in January, as a very encouraging trend.

Still, he warned that the pandemic was not yet over and urged caution, even as many countries have dropped their coronavirus protocols and segued into trying to live with the virus.

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.
