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. At this time, Lincoln Laboratory has extended its flexible work policy through the end of 2021.

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, the Laboratory requires mask wearing for all individuals, regardless of vaccination status. All individuals are also expected to maintain social distancing (six feet or more) whenever possible while on site at the Laboratory.

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 must agree to wear a mask and socially distance, regardless of vaccination status. Only visitors who have a valid COVID Visitor Pass will be able to enter Laboratory facilities. Visitors may access the COVID Visitor Pass app via The COVID Visitor Pass is good until midnight and requires an initial acknowledgement of compliance to access the Laboratory, a daily health attestation, and a vaccine status attestation. Visitors who are fully vaccinated must present proof of vaccination. Visitors who are not fully vaccinated must provide proof of a negative COVID test taken no more than three days before their visit.  

Please see the user guide for more information. 

The paper self-attestation form will be available to visitors, if required.  Visitors may bring a completed copy of the Visitor Screening Questionnaire with them (completed no more than 24 hours prior to their visit) or can complete the form on site.

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.

  • Self-Isolation and Medical Quarantine

If you meet the criteria for self-reporting, you should follow all recommended steps, including self-isolation or quarantine depending on your status:

  • For fully vaccinated individuals: If you are found to be COVID-positive, you must quarantine from the Laboratory for 10 days.
  • For fully vaccinated individuals who have had close contact with a COVID-positive person: You must test 3–5 days following a known exposure. You must self-isolate from the Laboratory until proof of negative test result is received.
  • For unvaccinated individuals: If you are found to be COVID-positive, you must quarantine for 14 days. You may return to the Laboratory on Day 15, pending no symptoms.
  • For unvaccinated individuals who have had close contact with a COVID-positive person:  You must test 3–5 days following a known exposure. You must self-isolate from the Laboratory for 10 days. You may return to the Laboratory on Day 11, pending no symptoms.
Testing is advised for fully vaccinated individuals who return from travel.

  • Do not come into work and avoid going out in public, to avoid spreading the disease further.  
  • Call your supervisor if you need to retrieve items from work, so that we can arrange for delivery.
  • Continue to work from home, if you feel well enough and are equipped.
Medical quarantine

If you have been diagnosed with presumptive or confirmed COVID-19
