President Donald Trump assured Americans the risk from coronavirus remained "very low," and placed Vice President Mike Pence in charge of the U.S. response to the looming global health crisis.
At a White House briefing with his coronavirus task force, Trump said public health officials were preparing to do "whatever we have to" to deal with the outbreak.
He said he would accept whatever amount of emergency spending Congress decided to allocate, and was not immediately considering travel restrictions to and from countries such as South Korea and Italy that are dealing with outbreaks.
"The risk to the American people remains very low," Trump said, flanked by Pence and public health officials.
"We're ready to adapt and we're ready to do whatever we have to as the disease spreads, if it spreads," he said, adding the spread of the virus in the United States was not "inevitable."
Frequently Asked Questions
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.
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.
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.
"It probably will, it possibly will. It could be at a very small level, or it could be at a larger level. Whatever happens we‘re totally prepared," he said.
