Covid-19 Updates

June 30, 2021

The Institute campus remains partially reopen with access restricted to IAS Faculty, Members and Staff only. At this time, our academic campus is not open to non-essential visitors, members of the public, or family members, including children.

The Health Screening Form must be completed each morning before coming to campus and approved by the IAS Covid-19 Response Team. 

Fully vaccinated individuals at IAS:

  • Do not need to wear masks outdoors; indoors when in their offices, alone or with others who are fully vaccinated; or indoors in public spaces (hallways, activities building, libraries, laundry).
  • Do not need to quarantine after having close contact with someone with Covid-19, as long as they remain asymptomatic.
  • Do not need to quarantine or get tested before/after domestic travel unless otherwise required by their destination.

Unvaccinated individuals at IAS:

  • Are required to wear masks indoors and outdoors.
  • Must adhere to the six-foot social distancing guidelines.
  • Do need to quarantine after having close contact with someone with Covid-19.

For more information on risk for vaccinated versus unvaccinated individuals, the CDC has guidance on “Choosing Safer Activities.”


Masks are required on planes, trains, buses, and other forms of public transportation traveling into, within, or out of the United States and in U.S. transportation hubs such as airports and stations.

New Jersey’s domestic travel advisory is no longer in effect. 
New Jersey residents returning home and travelers visiting the state do not need to quarantine, but should follow travel guidance from the CDC, the NJ Department of Health, and local health and safety protocols of their travel destination. At this time, the CDC still recommends delaying travel until you are fully vaccinated and that unvaccinated individuals get tested 1–3 days before their trip, 3–5 days after travel, and stay home and self-quarantine for 7 days after travel.

International Travel
The CDC has travel restrictions to the United States from certain countries. All air passengers arriving in the United States from a foreign country are required to get tested for Covid-19 no more than 3 days before their flight departs and to present the negative result, or documentation of having recovered from Covid-19, to the airline before boarding the flight.

In addition, with specific exceptions, foreign nationals who have been in any of the following countries during the past 14 days may NOT enter the United States: India, China, Iran, countries in the European Schengen Area, the United Kingdom, the Republic of Ireland, Brazil, and South Africa. For a full list of exceptions, refer to the CDC's update on travelers prohibited from entry.

IAS is no longer requiring the completion of a Travel Questionnaire, and academically related travel can resume in accordance with current guidelines.

We have created a series of Return-to-Campus guides as a resource for the IAS community to help navigate returning to IAS during the partial reopening. The guides feature more in-depth information than shown on the website, and should be consulted before coming to campus. All current and future guides may be found at this link.
