Tips for a comfortable vaccination experience

Some people may experience pain or discomfort from vaccination because of the needle. But there are a number of techniques you can use to make the vaccination more comfortable and limit pain or discomfort.

Some helpful strategies include:

Possible side effects and reactions

After getting vaccinated, it's common and normal to have temporary side effects. These can last a few hours to a few days after vaccination.

This is the body's natural response, as it's working hard to build protection against the disease.

Common vaccine side effects may include:

Symptoms at the injection site, such as: Flu-like symptoms, such as:
  • redness
  • soreness
  • swelling
  • chills
  • fatigue
  • joint pain
  • headache
  • mild fever
  • muscle aches

Managing common side effects at home

You can take medicine after your vaccination to help with any pain or to lower a fever. Ask your health care provider what they recommend to manage symptoms.

You can also:

Allergic reactions

Allergic (anaphylactic) reactions are very rare. Symptoms of an allergic reaction include:

Call 911 right away if you develop any serious symptoms after vaccination or symptoms that could be an allergic reaction.

Reporting a possible serious reaction

You should also report any serious reactions or side effects to your health care provider. Reported allergic reactions and side effects to COVID-19 vaccines are published weekly:

After getting vaccinated

The person vaccinating you will let you know where to wait and for how long after vaccination. The usual wait time is about 15 minutes or more. This allows time for you to be watched for possible reactions or side effects. Let someone know if you're experiencing any symptoms following vaccination.

After vaccination, ask for a record of any vaccines you receive.

Most COVID-19 vaccines require 2 doses. While current evidence shows good effectiveness after 1 dose, a second dose is essential for longer-lasting and optimal protection. For your second dose, return at the time advised by your health care provider.

Continuing public health measures

It isn't yet known whether the spread of COVID-19 can be stopped by vaccination alone. Because of this, it's essential that everyone continue to follow public health measures to help stop the spread of COVID-19 in our communities.

As more vaccines are given, some of the more restrictive public health measures can be lifted. Learn more about life after vaccination.


Starting July 5, 2021, there will be some exemptions for people who are eligible to enter Canada, who also meet specific conditions for fully vaccinated travellers.
