The new CDC guidelines are a reflection of just how good the Covid-19 vaccines are

The Covid-19 vaccines available in the US are highly effective against the virus. Until recently, though, that wasn’t reflected in CDC recommendations for how vaccinated people could act.

Before the update, the CDC rules said that vaccinated people do not need to quarantine for 14 days after an exposure to the virus. But that was the only difference between the CDC guidance for vaccinated people and their guidance for those who weren’t.

For weeks, experts have been expressing frustration that the CDC guidelines don’t share more that vaccinated people can do. “Advising people that they must do nothing differently after vaccination — not even in the privacy of their homes — creates the misimpression that vaccines offer little benefit at all. Vaccines provide a true reduction of risk, not a false sense of security,” epidemiologist Julia Marcus argued in the Atlantic.

“CDC’s continuing delay in issuing guidance for what vaccinated people can do illustrates a broader problem: Public health has chosen caution over celebration” when it comes to the Covid-19 vaccines,” Leana Wen of George Washington University’s School of Public Health argued Friday on Twitter and in the Washington Post. “If this doesn’t change, Americans could be dissuaded from being vaccinated, and our country might never achieve the goal of herd immunity.”

Among those experts, the new guidelines were greeted with relief. “CDC totally gets it right,” Ashish Jha of the Brown University School of Public Health responded. “Vaccinated people can hang with other vaccinated people. Vaccinated grandparents can hug unvaccinated grandkids. Broader public health measures should remain for now because lots of high risk folks are not yet vaccinated.”

The new guidelines don’t encourage the full return to normalcy that we all long for just yet. But the reassurance that vaccinated people can invite other vaccinated people over for unmasked indoor hangouts, spend time with unvaccinated family members if they’re not at elevated risk, and expect more guidance as more data comes in represents a light at the end of the tunnel for many Americans desperate to hear that they can have their lives back. And it reflects the science, which points to the vaccines being highly effective at reducing risk to the vaccinated person and risk to others.

Covid-19 vaccinations are increasing, with several record days last week and estimates from the Biden administration that the vaccines will be available to all adults by the end of May (90 million doses have been given so far, with exact eligibility criteria varying by state). As more and more Americans join the ranks of the vaccinated, these guidelines are encouraging evidence that a return to normalcy really is just around the corner — and worth waiting for.
