Mapping Los Angeles’ Unequal COVID-19 Surge

Not long after those first cases were found, experts began warning about how it would disproportionately hurt poorer people, whose jobs were likely to be deemed essential, and who were likely to be members of communities of color. But what’s been less discussed is the role of deeply rooted inequality — long magnified in California — in driving the rampant spread of the virus.

It’s been slightly more than a year since what we used to call the novel coronavirus was first detected in California.

Not long after those first cases were found, experts began warning about how it would disproportionately hurt poorer people, whose jobs were likely to be deemed essential, and who were likely to be members of communities of color.

But what’s been less discussed is the role of deeply rooted inequality — long magnified in California — in driving the rampant spread of the virus.

Over the weekend, my colleagues on The New York Times’ graphics desk and I published a piece looking at how that has played out in Los Angeles County, the epicenter of the pandemic in the United States, neighborhood by neighborhood.

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.
