Where We Are with Vaccines and Treatments for COVID-19

With confirmed COVID-19 cases worldwide surpassing 9 million and continuing to grow, scientists are pushing forward with efforts to develop vaccines and treatments to slow the pandemic and lessen the disease’s damage.

Some of the earliest treatments will likely be drugs that are already approved for other conditions, or have been tested on other viruses.

“People are looking into whether existing antivirals might work or whether new drugs could be developed to try to tackle the virus,” said Dr. Bruce Y. Lee, a professor at the CUNY Graduate School of Public Health & Health Policy.

As of May 8, two medicationsTrusted Source had received emergency use authorization (EUA) from the Food and Drug Administration (FDA): the antiviral remdesivir and a drug used to sedate people on a ventilator.

The FDA issued an EUA in March for the antimalaria drugs chloroquine and hydroxychloroquine, but later revoked itTrusted Source after studies showed that they’re unlikely to be effective in treating COVID-19.

An EUA allows doctors to use these drugs to treat people with COVID-19 even before the medications have gone through the formal FDA approval process.

These drugs are still being tested in clinical trials to see whether they’re effective against COVID-19. This step is needed to make sure the medications are safe for this particular use and what the proper dosage should be.

It could be months before treatments are available that are known to work against COVID-19. It could be even longer for a vaccine.

But there are still other tools we can use to reduce the damage done by the new coronavirus, also known as SARS-CoV-2.

“Even though technological advances allow us to do certain things more quickly,” Lee told Healthline, “we still have to rely on social distancing, contact tracing, self-isolation, and other measures.”
