Can the Covid Vaccine Protect Me Against Virus Variants?

Vaccines do a good job of protecting us from coronavirus, but fear and confusion about the rise of variants have muddled the message. Here are answers to common questions.

The news about coronavirus variants can sound like a horror movie, with references to a “double-mutant” virus, “vaccine-evading” variants and even an “Eek” mutation. One headline warned ominously: “The devil is already here.”

While it’s true that the virus variants are a significant public health concern, the unrelenting focus on each new variant has created undue alarm and a false impression that vaccines don’t protect us against the various variants that continue to emerge.

“I use the term ‘scariants,’” said Dr. Eric Topol, professor of molecular medicine at Scripps Research in La Jolla, Calif., referring to much of the media coverage of the variants. “Even my wife was saying, ‘What about this double mutant?’ It drives me nuts. People are scared unnecessarily. If you’re fully vaccinated, two weeks post dose, you shouldn’t have to worry about variants at all.”

Viruses are constantly changing, and new variants have been emerging and circulating around the world throughout the pandemic. Some mutations don’t matter, but others can make things much worse by creating a variant that spreads faster or makes people sicker. While the rise of more infectious variants has caused cases of Covid-19 to surge around the world, the risk is primarily to the unvaccinated, for whom there is great concern. While vaccination efforts are well underway in the United States and many other developed countries, huge swaths of the world’s population remain vulnerable, with some countries yet to report having administered a single dose.
