The United States on Sunday entered one of the most critical weeks so far in the coronavirus crisis, with government officials warning that the death toll in places such as New York, Michigan and Louisiana was a sign of trouble to come in other states.

Still, governors of eight states resisted issuing stay-at-home orders aimed at slowing the spread of the respiratory disease, and some churches held large Palm Sunday services in defiance of such orders in their states.

New York, the hardest-hit state, reported on Sunday that for the first time in a week, deaths had fallen slightly from the day before, but there were still nearly 600 new fatalities and more than 7,300 new cases. Places such as Pennsylvania, Colorado and Washington, D.C., are starting to see rising deaths.

"This is going to be the hardest and the saddest week of most Americans' lives, quite frankly. This is going to be our Pearl Harbor moment, our 9/11 moment, only it's not going to be localized," U.S. Surgeon General Jerome Adams warned on Fox News on Sunday. "It's going to be happening all over the country. And I want America to understand that."

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.
