Laboratory response to COVID-19

MIT Lincoln Laboratory is closely monitoring the COVID-19 pandemic and will communicate the appropriate responses, adapt Laboratory policies as needed, and provide resources for the Laboratory community to stay safe. This is a rapidly evolving situation and protecting the health and safety of the MIT community is paramount. We encourage employees to continue to visit the COVID-19 Pandemic website on our intranet. 

COVID-19 control and prevention protocols

Lincoln Laboratory complies with Centers for Disease Control and Prevention, Department of Defense, Commonwealth of Massachusetts, and MIT Medical guidance on infection control and prevention. We expect our employees, visitors, and contractors to comply with this guidance.

At this time, masks are optional. However, individuals must wear a mask on MIT shuttles, at MIT Medical, and for five days after returning to work from isolation or quarantine. Masks are recommended for individuals who are unvaccinated or have health concerns.

The Laboratory has taken aggressive steps to enhance workplace sanitization, including frequent wipe-down of commonly touched surfaces, increased custodial services, increased disinfection of common spaces, and distribution of supplies to areas throughout the facility.

Lincoln Laboratory conducts internal contact tracing if (a) an employee tests positive, (b) an employee exhibits COVID-19 symptoms, or (c) an employee has had close contact with others and is unwell. Contact tracing identifies people, facilities, and parts/materials that may have been exposed to the coronavirus. All close contacts are asked to self-isolate, and all identified rooms, areas, and materials used by the ill person are sanitized or isolated as appropriate.

  • Vaccination

To safeguard our health and well-being, MIT Lincoln Laboratory requires COVID-19 vaccination for all employees and subcontractors. Individuals may request exemption from the vaccine requirement for medical or religious reason.

Laboratory field sites

Lincoln Laboratory’s priority is protecting the health and safety of all employees. Personnel at all field sites and offices staffed by Laboratory personnel should follow the advisories and directives issued to Laboratory personnel in Massachusetts and available at the COVID-19 Pandemic website on our intranet. Also, personnel at field sites and offices should monitor the guidance and policies provided by public health agencies of the states in which they are located.

Visitor information

  • Visitors to the Laboratory are advised to wear a mask if they are unvaccinated or have health concerns.
  • Visitors to the Laboratory should comply with the CDC's recommendations for travel.

Medical information

  • When and How to Self-Report

If you (or a member of your household) are experiencing COVID-19-like symptoms (fever, sore throat, new cough, new nasal congestion or new runny nose not related to seasonal allergies, muscle aches, new loss of smell, shortness of breath), or if you have had close, sustained contact with someone diagnosed with COVID-19, even if you are fully vaccinated, you should:

  • Stay at home and self-isolate until advised otherwise
  • Self-report to [email protected] and wait for reply
  • Use the MIT COVID Pass Self-Attestation App to report any symptoms
  • If your medical provider is not MIT Medical, contact your medical provider for guidance

Please Note: Your medical professional (including MIT Medical) will not share health information with the Laboratory, so it is important that you contact your supervisor and/or HR to report that you are self-isolating.
