Recommended Third Dose: If you have an immune system that is moderately to severely compromised, the CDC recommends you may receive an additional dose of mRNA COVID-19 vaccine if the second dose was received at least 28 days ago. People with moderately to severely compromised immune systems are especially vulnerable to COVID-19 and may not build the same level of immunity to the two-dose vaccine series compared to people who are not immunocompromised. This additional dose is intended to improve immunocompromised people’s response to their initial vaccine series.

Booster Dose: For individuals who received a Pfizer-BioNTech or Moderna COVID-19 vaccine, the following groups are eligible for a booster shot at 6 months or more after their initial series:

  • 65 years and older
  • Age 18+ who live in long-term care settings
  • Age 18+ who have underlying medical conditions
  • Age 18+ who work or live in high-risk settings

For the nearly 15 million people who got the Johnson & Johnson COVID-19 vaccine, booster shots are also recommended for those who are 18 and older and who were vaccinated two or more months ago.

Lyster is administering Moderna for Booster/Third Doses and scheduled appointments.
