Exposure After Vaccination

Vaccinations are one of the best protections against COVID-19, especially for our most vulnerable populations. Here are the Wyoming Department of Health’s most recent guidelines on what to do if you’ve been exposed to COVID-19 after being vaccinated. Vaccinated persons with an exposure to someone with confirmed or suspected COVID19 are not required to quarantine if they meet all of the following criteria:

  • Are fully vaccinated (it has been at least 2 weeks following receipt of the second dose in a 2-dose series)
  • Are within 3 months following receipt of the last dose in the series
  • Have remained asymptomatic since the current COVID-19 exposure
  • Individuals who meet the above criteria should still monitor themselves for symptoms for 14 days after exposure and isolate and seek medical attention if symptoms develop
  • If it has been longer than 3 months since the vaccine series was completed, vaccinated persons must quarantine after exposure (similar to current guidance around immunity following infection)
  • CDC and WDH continue to recommend fully vaccinated healthcare providers do not work for 14 days after an exposure, given the potential consequences of transmitting COVID-19 within a healthcare setting. However, this updated quarantine guidance for fully vaccinated persons can be considered if needed to alleviate staffing shortages. Fully vaccinated healthcare providers do not need quarantine outside of work.
  • CDC recommends vaccinated inpatients and residents in healthcare settings should continue to quarantine after an exposure due to the high risk and severe consequences of transmission in these settings. WDH will follow this guidance but will continue to evaluate whether quarantine procedures can be relaxed in residential settings.
  • Vaccinated persons should continue to follow current guidance to protect themselves and others, including wearing a mask, staying at least 6 feet away from others, avoiding crowds, avoiding poorly ventilated spaces, covering coughs and sneezes, washing hands often, following CDC travel guidance, and following any applicable workplace or school guidance, including guidance related to personal protective equipment use or SARS-CoV-2 testing.
