What Can You Do Once You’re Vaccinated?

Americans have entered a new phase of the pandemic where a large number of them are vaccinated but most are not. That leads to a big question: What can you do after you’re fully vaccinated? The Centers for Disease Control and Prevention recently issued new guidelines, and other experts have weighed in with their thoughts.
But when it comes to what you personally should or shouldn’t do, you will need to do your own risk assessment. I spoke to experts to develop a science-backed framework for post-vaccination decision-making. Here are important factors to keep in mind that, when paired with your own appetite for risk, can help you navigate this next stage of the pandemic.
What are you doing?
These questions do not take into account every possible factor relating to risk of infection, but they’re a place to start. How long an activity is and how ventilated the space will be play the biggest roles in safety. Even if you don’t know the ventilation system used in an indoor space, you can see if there’s an attempt to increase it, such as opening doors and windows.
Public health officials use 15 minutes as the threshold of exposure to determine if someone is at risk for infection. We chose one hour to represent a moderately high risk.
Whom will you be with?
New C.D.C data suggests that the authorized Covid-19 vaccines reduce the risk of getting and spreading the coronavirus. There is still a small chance after vaccination that you can get the virus and spread it.
Who is in your circle?
Young children cannot receive the vaccines yet, but they also are less likely to require hospitalization or die from Covid-19, unless they have an underlying condition or are high risk. They can still spread the virus, though. People with immune-compromising conditions (like cancer, H.I.V., organ transplants, etc.) can receive the vaccines, but scientists don’t yet know how well the vaccines protect them.
Where do you live or where will you be?
The C.D.C defines a high transmission rate of the coronavirus as 100 total cases per 100,000 people. Your county has a total of cases per 100,000 over the past seven days, giving it a risk rating
Test positivity refers to the proportion of tests in your community coming back positive. Your county has a test positivity rate of
The transmission rates where you live and where you’re headed are helpful data points, though not the whole story. Other people may be traveling from areas with different rates, and transmission and test positivity rates more broadly depend on testing availability and frequency. Regardless, knowing the rates offers a rough benchmark for thinking about the infection risk within the community.
Your own health
All the vaccines authorized by the F.D.A. have been found to protect against death from Covid-19, and from severe disease and hospitalization. Still, the risk of infection is not zero.
How comfortable are you with the risk in these five areas?
Now comes the tricky part: You have to weigh this knowledge against your own personal tolerance for risk. Are you a big risk taker or more conservative? It probably depends on the particular situation.
Only you can determine this risk-benefit calculation: Is a given activity worth the levels of risk based on the questions above? Are the risks primarily to you, or do they extend to others you care about? Some people may find that the activity is generally low risk, but having just one high-risk, unvaccinated person in their circle might dissuade them from participating. Is this a once-in-a-lifetime experience? Some events, like weddings, for example, will never happen again. Others, like travel to a foreign country, are easier to delay.
As has been the case since the pandemic began, be prepared to change your plans if the situation or science changes. As time goes on, for example, researchers will learn more about how long immunity from the vaccines last, and how effective the vaccines are against new variants that arise. In the meantime, as you come to understand the biggest factors that make any situation more or less safe, as well as your own personal risk threshold, post-vaccination decision making becomes easier — and life more enjoyable.
