A Collapse Foretold: How Brazil’s COVID-19 Outbreak Overwhelmed Hospitals

More than a year into the pandemic, deaths in Brazil are at their peak and highly contagious variants of the coronavirus are sweeping the nation, enabled by political dysfunction, widespread complacency and conspiracy theories. The country, whose leader, President Jair Bolsonaro, has played down the threat of the virus, is now reporting more new cases and deaths per day than any other country in the world.

The patients began arriving at hospitals in Porto Alegre far sicker and younger than before. Funeral homes were experiencing a steady uptick in business, while exhausted doctors and nurses pleaded in February for a lockdown to save lives.

But Sebastião Melo, Porto Alegre’s mayor, argued there was a greater imperative.

“Put your life on the line so that we can save the economy,” Melo appealed to his constituents in late February.

Now Porto Alegre, a prosperous city in southern Brazil, is at the heart of a stunning breakdown of the country’s health care system — a crisis foretold.

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.
