The Centers for Disease Control and Prevention released new guidelines Monday on gatherings for vaccinated people and households, loosening some of the precautions for households where everyone has been inoculated, NBC News reports.

Stressing that people should continue to take precautions even after getting the vaccine, the CDC guidelines provide for the ability of people in households where all adults have been vaccinated to visit with household that have one or more people who have not been vaccinated.  Fully vaccinated groups can gather in small numbers in indoor settings.

If no one in the unvaccinated household is at high risk for severe COVID, the gatherings can take place indoors and without masks; however, if any person is at high risk, the CDC recommends staying outside, social distancing and wearing masks.

“This guidance represents a first step toward returning to everyday activities,” the CDC said in a media statement.   “For example, fully vaccinated grandparents can visit indoors with their unvaccinated healthy daughter and her healthy children without wearing masks or physical distancing, provided none of the unvaccinated family members are at risk of severe COVID-19.”

The revised guidelines allow families to gather, two households at a time to minimize risks to those people unvaccinated.

The public health recommendations suggest to continue to avoid large groups of unmasked people and groups from multiple households.  It suggests that, because the vaccine is not deemed 100% effect, people who develop symptoms of COVID should immediate isolate and seek medical help.
