What is the COVID-19 Delta variant and how can I protect myself?  

By Bailey Smith

The COVID-19 Delta variant is more contagious than the original COVID-19 strain and can be spread by individuals who are fully vaccinated. Univera Healthcare Vice President of Medical Affairs for Commercial Products, Lisa Y. Harris, MD, shares the latest information on the Delta variant as of August 10, 2021.

Dr. Harris, what is the Delta variant? Is it true that it spreads more easily?

Viruses are constantly mutating or changing. This can lead to new versions of a virus that are known as variants. The Delta variant is a mutation of the COVID-19 virus and, from what experts know, is more contagious and spreads more easily than the original strain. It accounts for more than 80% of newly diagnosed cases in the U.S., according to the U.S. Centers for Disease Control (CDC).

How does the Delta variant affect those who are unvaccinated versus fully vaccinated?

Although more contagious, there is no data that suggests the Delta variant causes more serious symptoms than the original COVID-19 strain. The vast majority of people with serious symptoms are unvaccinated. For those who are fully vaccinated, we know that no vaccine grants 100 percent immunity so there will be some breakthrough cases, but the COVID-19 vaccines still greatly reduce the risk of major illness. Symptoms will be milder, and you are less likely to be hospitalized, if you are vaccinated. CDC data, as of August 2, shows that less than 1 percent of fully vaccinated Americans experience a breakthrough infection, and 97 percent of COVID-19 patients in hospitals are unvaccinated.

How can someone protect themselves from the Delta variant?

Getting a COVID-19 vaccine remains the safest way to protect yourself. If you’ve gotten the first shot of a two-shot regimen (those from Pfizer and Moderna), make sure to get the second shot since early evidence suggests this is especially important for protecting against the variants. If you are not vaccinated, get the vaccine. If you can, practice social distancing, wear a mask when near other people, and avoid indoor social gatherings. Even those who are fully vaccinated should consider wearing masks in areas of high transmission. People with a weakened immune system need to be even more careful. Regardless of your vaccination status, stay home and away from others if you’re feeling ill or have been exposed to COVID-19.

How can someone protect younger family members? 

Parents of children ages 12 and older should have their children vaccinated. Over 94,000 children were diagnosed with COVID at the beginning of August, according to the American Academy of Pediatrics, and hospitals nationwide are reporting more and more children in their pediatric COVID units. It is important to protect younger children for whom data will be submitted to the FDA in September for vaccine authorization. In the meantime, remember the three W’s, and make them a top priority. Wash hands, Wear a mask, and Watch your distance in public.
