Before and After your COVID-19 Vaccine

The COVID-19 vaccine should be given alone and apart from other vaccines. Other vaccines should be scheduled 14 days before or 28 days after the COVID-19 vaccine. The health care provider at the clinic will ask you to reschedule your appointment if have received another vaccine in the past 14 days of your appointment.

Thank you for getting vaccinated at a Niagara Region Public Health COVID-19 vaccine clinic! Getting vaccinated will protect you against severe COVID-19 illness and hospitalization.

Once you arrive, you will be asked to provide consent. Read the Ministry of Health documents for your age group and this page so that you'll be ready to provide consent at the clinic:

Before you leave for your vaccine

  • Screen yourself for symptoms of COVID-19 (see Step 2: Screening under "At the clinic"). If you booked an appointment and you're feeling unwell on the day of your appointment, cancel and book a COVID-19 test.
  • Take any regular medication
  • Make sure to eat before coming to the vaccination clinic to prevent feeling faint or dizzy while being vaccinated
  • Wear a loose-fitting top or a t-shirt
  • Dress for the weather, as you may need to wait outside

What to bring

  • If you booked an appointment, the booking appointment confirmation number you received when you made your appointment
  • Your green health card. You can still get vaccinated if you don't have a health card. Bring another government-issued photo identification with you.
  • A mask
  • A screenshot or photo of your screening results if you complete screening before the onsite screening
  • Youth can bring an object with them to get their mind off the needle. For example, a mobile device, fidget spinner or book. They can also bring a person with them for support, such as a family member.

For more information, read the Ministry of Health documents about what you need to know before your COVID-19 vaccine appointment for your age group:

At the clinic

Step 1: Arrival

Upon arrival, let the outdoor clinic staff know if you have an appointment or if you're a "walk-in".

Step 2: Screening

Each person entering the vaccination clinic must complete an individual screen. You have three options to complete the screening.

  • Option 1: Before you line up. Answer the questions online and take a screenshot, or picture on your mobile if using a desktop computer, of the results page for each person who is entering the clinic. You will need to show your results at the screening desk.
  • Option 2: In the lineup. Follow the instructions for self-screening on the 'Get Screened for COVID-19' sign outside the clinic using your smartphone. Remember to take a screenshot of the results page for each person who is entering the clinic. You will need to show your results at the screening desk.
  • Option 3: At the screening desk. If you don't have a screenshot of your results, clinic staff will ask you the screening questions for COVID-19.

You will be given a handout to read with information about the vaccine. The handout will also have a list of questions the health care provider will ask you in Step 5.

If you're told not to enter the vaccination clinic because you're at increased risk of COVID-19 transmission, you will need to defer your vaccination. If you booked an appointment, you can reschedule.

Step 3: Check-in

You will be called to a registration desk where your green health card will be scanned.

Step 4: Vaccination

You will be directed to a table to get your COVID-19 vaccination.

Public Health plans to have both mRNA vaccines at our clinics. You will be offered the same mRNA vaccine that you got at your first appointment. This means you can choose which vaccine you get at the clinic, while supplies last.

If you have fainted, or became dizzy with previous vaccinations or procedures, or if you have a high level of fear about injections, tell the health care provider so that appropriate supports can be offered.

If the health care provider at the vaccination clinic advised you to defer your COVID-19 vaccination, you will need to defer your vaccination. If you booked an appointment, you can reschedule.

Step 5: Waiting area

You will sit in our waiting area for 15 minutes after getting vaccinated. Sit on a chair that has papers on the seat. This means your chair has been cleaned and disinfected. Make sure the sticker you're given is visible. Don't put your coat or sweater on top of the sticker.

Step 6: Check-out

You will receive proof of vaccination that you can take with you.

Save the selfie

Wanting to get a COVID-19 vaccination selfie? Tag us on social @NRPublicHealth using #StickItToCOVID and #VaccinateNiagara. We just ask that you wait until you're outside of the clinic space to take your picture. Other people at the clinic may not want to be in your photo. Please respect each other’s privacy and don't take photos or videos in the clinic space.

After getting your COVID-19 vaccine

For more information on what to expect in the days after vaccination, read the Ministry of Health's After Your COVID-19 Vaccine document.

It takes 14 days to start getting immunity from your vaccine. After that time, your risk of getting COVID-19 is much lower. If you do get COVID-19, the vaccine can prevent severe illness and death.

The only long-term impact of the vaccine is immune memory against COVID-19. This is because your body breaks down and gets rid of the mRNA as soon as it's finished using the mRNA's instructions. Once the mRNA breaks down, your body doesn't have the ability to produce more.

Learn more from Dr. Hirji about what to expect after your first dose. You are fully vaccinated 14 days after receiving the full series of a vaccine authorized in Canada.

Full vaccination is the greatest protection you can have against COVID-19 and its variants. Using multiple layers of prevention provides the additional protection, especially if you cannot avoid closed spaces, crowded places and close contact. Find out how to keep healthy and prevent the spread of COVID-19 after vaccination.
