Vaccines against COVID-19

Marcel Giguère, pharmacist

Since Covid-19 vaccination has already or will soon begin in senior residences (RPPs), I think it is appropriate to provide an update on the effectiveness and safety of these vaccines.

Treatments:
Few treatments exist against the Covid-19 virus and these are, to date, not very effective or difficult to access. Controlling the inflammatory reaction with a cortisone derivative is currently the most widely used treatment to reduce mortality, with some success. Colchicine, an old anti-gout drug, may also help reduce complications, but not prevent the disease.

Covid-19 Vaccines:
But the only hope to stop this pandemic is through the acquisition of a collective immunity where 70% and more of the population would be vaccinated against this virus. Just as the polio virus was almost eliminated from the planet by mass vaccination of the population,   COVID-19 CAN ALSO BE ELIMINATED BY VACCINATION!

There are currently 2 vaccines against Covid-19 approved by Health Canada: the one from Pfizer and the one from Moderna. These 2 vaccines require 2 doses to be injected: the first dose ensures immunity and the second, long-term effectiveness. Other vaccines will also soon be approved, including the Johnson & Johnson vaccine, which will require only one dose to be effective.

Efficiency:
More than 70,000 people have participated in the clinical studies of the 2 vaccines approved by Health Canada and their effectiveness has been evaluated around 95%! It should be noted that, to be effective, we must count on a period of approximately 14 days after the injection of the first dose. It was also noted that those who were still infected by the virus, despite their vaccination, generally had a less severe infection than those not vaccinated.

Effects:
The main side effects are minor. More than 50% of people vaccinated will have arm pain; between 10-50% of people will have headaches, joint pain, diarrhea or swollen glands under the arms. As for severe allergic reactions, they occur in only 4 out of every 100,000 people and the vaccination centers are equipped to treat these people on the spot, so there is no reason to worry about receiving these vaccines.

If you have any questions about your eligibility for these vaccines or about their effectiveness or safety, don't hesitate to discuss them with your pharmacist: he or she will be able to advise you well. Finally, we can see the light at the end of the tunnel with the Covid-19 vaccination.

 

Conclusion:

Information regarding the Quebec Covid-19 vaccination process is constantly evolving. It is now confirmed that you must be a Quebec resident aged 70 years and older to book an appointment for the Covid-19 vaccination. You can start making an appointment by going to https://www.quebec.ca/vaccincovid or by calling 1-877-644-4545.

Route of administration:

COVID-19 vaccines are administered as an intramuscular (IM) injection into the deltoid muscle (Comment: The vaccines mentioned here are Pfizer-BioNTech's Covid-19 vaccine and Moderna COVID-19 vaccine).

Intramuscular (IM) injections

The deltoid muscle of the arm is the preferred injection site in adolescents and adults (unless muscle mass is not adequate, in which case the anterolateral thigh may be used).
