President Donald Trump declared a US national emergency over the quickly spreading coronavirus on Friday, opening the door to more government aid to combat a pathogen that has infected more than 138,000 people worldwide and left over 5,000 dead.

The impact of the coronavirus on everyday life deepened around the world. It was detected for the first time in several countries, with the World Health Organization (WHO) calling Europe the pandemic's current epicentre. More schools and businesses closed, the global sporting calendar was left in tatters, and people faced greater restrictions on where they could go.

"To unleash the full power of the federal government to this effort today, I am officially declaring a national emergency - two very big words," Trump said in remarks at the White House Rose Garden, adding that the US situation could worsen and "the next eight weeks are critical."

Trump, whose action makes available $50 billion in federal aid to states and localities, had faced criticism from some experts for being slow and ineffective in his response to the crisis and playing down the threat.

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.
