COVID-19 Vaccine Frequently Asked Questions
You have questions about the vaccine, and we want to provide you with all the facts. Here are a few frequently asked questions about the COVID-19 vaccine.
How can we trust that the vaccine will be safe long term?
There is a rigorous testing process that happens before a vaccine gets approved, and safety is a key factor that is examined. Follow up studies are also conducted on vaccines to look at longer term effects. The vaccines currently approved for other diseases (e.g., flu, hepatitis B, etc) all have excellent safety profiles and the same standards apply to any COVID-19 vaccine used in Canada.
Do I have to get the vaccine now? I would rather wait a few more months to see what kinds of reactions other people experience after getting the vaccine?
While health care workers are among the first groups in Canada to be eligible to receive the vaccine, it’s important to remember that tens of thousands of people have already received the vaccine during the clinical trial phase. Trial participants reported relatively minor side effects such as fatigue, headache, chills, muscle pain, fever and joint pain, which generally resolved after a day.
How many people need to get the vaccine in order for it to be effective?
Generally speaking, a large number of people need to receive the vaccine in order to generate herd immunity, so that people who can’t get the vaccine (such as those with immunodeficiencies) still benefit from the protection. Researchers won’t know what the herd immunity threshold for this particular vaccine is until after vaccination and monitoring actually begins, but early predictions start at around 75%.
