− If you are not immunocompromised, you should receive your first booster dose at least
two months after the primary dose. It is recommended to receive an mRNA vaccine (Pfizer,
Moderna) for the first booster dose. Additionally, if you are 50 years and older, you should
receive a second booster dose using an mRNA vaccine (Pfizer, Moderna) at least four
months after your first booster. If you are 18 through 49 years, you may receive a second
booster dose using an mRNA vaccine (Pfizer, Moderna) at least four months after your first
booster (Johnson & Johnson cannot be used for the second booster dose).
Do minors need consent to receive vaccinations?
Yes. Minors ages 5 through 17 will need a parent or legal guardian consent to be vaccinated.
How will I know which brand of vaccine I received?
You will receive a COVID-19 Vaccination Record Card which will tell you which brand of vaccine you
received and when you are due for a next dose, if required. It is important to keep this card.
What can I do if I lose my COVID-19 Vaccination Record Card, it is damaged, or if I did not
receive a COVID-19 Vaccination Record Card?
Michiganders, ages 18 years and older, can access and download their immunization records from
the Michigan Care Improvement Registry (MCIR) on their computer or smartphone. Visit
Michigan.gov/MiImmsPortal to get started. If an immunization record can’t be found,
immunization records can be requested from a physician’s office or local health department.
− If you did not receive a COVID-19 Vaccination Record Card, contact the facility where you
were vaccinated and request either a completed card or a print-out from the Michigan Care
Improvement Registry (MCIR) if it was administered in Michigan, be given or sent to you.
Both are official vaccination records.
What is the difference between an mRNA vaccine and an adenovirus vaccine?
COVID-19 vaccines help our bodies develop immunity to the virus that causes COVID-19 without
us having to get the illness. Different types of vaccines work in different ways to offer protection,
but with all types of vaccines, the body is left with knowing how to fight the virus in the future.
Neither vaccine uses a live virus – you cannot get COVID-19 from a COVID-19 vaccine.
− mRNA vaccines give instructions to your cells to make a harmless piece of spike
protein from SARS-CoV-2 – the virus that causes COVID-19. Recognizing that the piece of
protein doesn’t belong there, your immune system builds antibodies and activates T-cells
to destroy it. In the future, your cells remember how to destroy the protein, protecting you
from the virus. View: How mRNA vaccines work.
− Adenovirus vaccine is a type of vector vaccine. This vaccine uses adenovirus (the
virus that causes the common cold) to deliver instructions about COVID-19 to your
cells through a piece of spike protein. Your immune system then builds antibodies and
activates T-cells to destroy it. In the future, your cells remember how to destroy the
protein, protecting you from the virus. View: How Adenovirus-based vaccines work.
