Canada vaccine approval could be days away


CBC News shows that Health Canada has yet to approve a vaccine for Coronavirus COVID-19. But Minister of Intergovernmental Affairs Dominic LeBlanc, who also chairs the federal cabinet committee on COVID-19 response, says he expects those approvals to come shortly.

It will be interesting to see what the effects of the vaccine will be on people in the long term. Throughout human history, it seems that the average vaccine takes about 10-12 years to be developed.

You might have thought about what are the phases of a vaccine trial. Clinical trials in humans are classified into three phases: phase I, phase II and phase III and in certain countries formal regulatory approval is required to undertake any of these studies.

These are the 3 phases of vaccine development: Exploratory stage. Pre-clinical stage. Clinical development.

Vaccine trials may certainly take months or years to complete, since a sufficient time period must elapse for the subjects to react to the vaccine and develop the required antibodies.

Some vaccines are made by taking toxins and inactivating them with a chemical (the toxin, once inactivated, is called a toxoid). By inactivating the toxin, it no longer causes disease. The diphtheria, tetanus and pertussis vaccines are made this way.

Vaccines really give you immunity to a disease without you getting sick first. They are made using killed or weakened versions of the disease-causing germ or parts of the germ (called antigens). For some certain vaccines, genetic engineering is used to make the antigens used in the vaccine.

The history of vaccines and immunization began with the story of Edward Jenner, a country doctor living in Berkeley (Gloucestershire), England, who in 1796 performed the world's first vaccination.

Vaccines can be made of various things. Killed (inactivated) vaccines are made from a protein or other small pieces taken from a virus or bacteria. The whooping cough (pertussis) vaccine is an example. Toxoid vaccines contain a toxin or chemical made by the bacteria or virus.

A vaccine effectively works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria.

There are 5 main types of vaccines:
attenuated (live) vaccines
inactivated vaccines
toxoid vaccines
subunit vaccines
conjugate vaccines

It seems that aluminum-containing adjuvants are vaccine ingredients that have been used in vaccines since the 1930s. Small amounts of aluminum really are added to help the body build stronger immunity against the germ in the vaccine. Aluminum is actually one of the most common metals found in nature and is present in air, food, and water.

It seems that everyone will have access to a Coronavirus COVID-19 vaccine in Canada. A useful vaccine will be available to everyone. Because of the unprecedented global funding and collaboration, more than 150 vaccine candidates are being researched around the world at this time.

The Government of Canada is investing in made-in-Canada research and has already made advanced purchase agreements of many hundreds of millions of doses of the most promising vaccine candidates from around the whole world. Canadians should expect access to safe and effective vaccines as soon as they are ready.

The official duration of COVID-19 quarantine in Canada exists. The Government of Canada has put in place emergency measures to slow the introduction and spread of COVID-19 in Canada. You must quarantine for 14 days, provide contact information and monitor yourself for symptoms subject to any Order made under the Quarantine Act imposing isolation or quarantine requirements upon entry.

Canada is making efforts to decrease the Coronavirus Covid-19 Pandemic.
