Yes, you can still be vaccinated if you don't have ID. Even though providing contact information may not be required to get a vaccine, staff at the vaccination site may still ask for ID. People who have ID can produce it, but those who can't show ID will not be turned away. You should bring an ID if you have one, to verify the name and eligibility information you submitted to the vaccination appointment system. Bring insurance information if you have insurance, and employment information in Connecticut if you work here but do not live in the state. You can still get the COVID-19 vaccine without insurance or an ID.
You do not need to pay, show ID, or have health insurance to get a booster.
You do not need to bring your CDC vaccine card or any proof of previous COVID-19 vaccine doses to get a booster. If you have your vaccine card it is helpful so that your booster dose can be added to it, but you do not need to show your CDC vaccination card to get your booster. You will be asked to self-attest that you meet eligibility requirements such as age, health conditions, or occupation.
There are no ID, or health insurance requirements. Your vaccinator may choose to look up your vaccine records to confirm the type of vaccine you received before.
