What Canadians Should Know About Each Authorize Covid-19 Vaccine?

The COVID-19 vaccine is used for protection against the SARS-CoV-2 virus (also known as COVID-19). COVID-19 is a new coronavirus strain that has triggered a worldwide pandemic. The virus is a cause respiratory sickness that produces an infection in the lungs and airways.

There are two types of COVID-19 vaccines approved in Canada.

  • mRNA vaccines
  • Viral vector-based vaccines

mRNA vaccine

mRNA Vaccines

The Pfizer-BioNTech and Moderna vaccines are mRNA vaccines.

mRNA vaccines contain messenger RNA (mRNA), which instructs your cells to produce a protein (called a spike protein). It is a spike protein similar to the one found on the surface of the COVID-19 virus. Because the protein isn't ordinarily found in your cells, your immune system reacts by producing antibodies against it. These antibodies will defend you and fight the virus; if you become exposed to the COVID-19 virus.

Viral vector-based vaccines

A virus that isn't COVID-19 is used in viral vector-based vaccinations to deliver information about the virus that causes COVID-19. This virus does not transmit COVID-19. It teaches your cells how to create a spike protein like the one found on the COVID-19 virus's surface. Your immune system produces antibodies against this protein as a result of this protein. These antibodies will defend you and fight the virus if you become exposed to the COVID-19 virus.

Who can take the COVID-19 vaccine?

  • Moderna: 18+
  • Pfizer: 12+
  • AstraZeneca: 18+
  • Janssen: 18+

How many doses of each COVID-19 vaccine are required? 

  • Moderna: two
  • Pfizer: two
  • AstraZeneca: two
  • Janssen: one

Can a pregnant or breastfeeding woman get the COVID-19 Vaccine? 

Yes,  pregnant or breastfeeding women must go for the COVID-19 vaccine. COVID-19 has a higher risk of making a woman sick if she is pregnant. It will reduce the chances of becoming seriously ill from the virus.  If you're pregnant or planning to become pregnant, you should get an mRNA COVID-19 vaccine. It is the safest type of COVID-19 vaccine to receive during pregnancy.

Are there any side effects of the COVID-19 Vaccine?

  • redness, swelling, itching, or feeling sore at the site of injection
  • headache
  • feeling tired or unwell
  • swollen lymph nodes
  • fever or chills
  • feeling nausea, vomiting, or diarrhoea
  • body aches or painful joints


Each of the vaccines has been found to fight coronavirus effectively. All don't offer the same level of protection, however. However, Canadians should be confident that each of the approved vaccines will cut the clutches of COVID 19 and protect them against the worst results of the virus. So all these vaccines are good in the areas where we genuinely look at preventing severe illness, preventing hospitalizations and, of course, preventing death.
