Covid 19 vaccine
Are you curious about the COVID 19 vaccine and what they include? Here's everything you need to know about the new vaccines and why it's important to get vaccinated.
The Covid 19 Vaccine protects people from the virus and other pathogens by fostering immunity. A Covid vaccine introduces a less harmful version of the germ, or something designed to appear or function like it, into a person’s body. The immune system creates antibodies against that germ, keeping the person from becoming ill if they come in contact with it again.
Among specific age groups, the Canadian Health Ministry has authorized COVID 19 vaccines for emergency use (COVID-19). Johns Hopkins Medicine considers all licensed COVID 19 vaccine to be highly successful in preventing life-threatening diseases, hospitalization, and death from COVID-19.
Canadian Approved Vaccines
The vaccine is recommended for people aged 12 years and older. Its safety and efficacy in persons under the age of 12 have yet to be determined.
Clinical trials showed that beginning 2 weeks after the second dose, the Moderna Spikevax®COVID vaccine was:
- In a trial of COVID-19 participants aged 18 and above, the efficacy was 96.1% in protecting COVID-19 infection.
- The vaccine prevented 100% of infections among trial participants 12 to 17 years old.
This immunization needs two doses for optimum protection.
Based on the results of clinical trials, Health Canada has authorized a dosing schedule of two doses one month apart.
Individuals age 18 and older who have completed their primary immunization series should get a booster dose of the Moderna Spikevax®COVID-19 vaccine six months after getting the rest of their vaccines.
When a person’s vaccination is due, the province or territory in which they live determines when they receive it.
Healthcare providers and policy makers should carefully consider the latest data and take public health recommendations into account while making those decisions.
The immunization is appropriate for those aged 12 and older. There hasn’t been enough evidence to determine whether it’s safe and effective in youngsters younger than 12 years of age.
This vaccine needs two doses to provide the greatest protection.
According to Health Canada’s dose regimen, which was established on the basis of clinical trial evidence, 2 doses are given 21 days apart.
Individuals 18 years of age and older who have already received the standard series may receive a booster dose of the Pfizer-BioNTech Comirnaty® COVID-19 vaccine.
The province or territory in which you reside determines when you get your doses of the vaccine.
The AstraZeneca Vaxzevria® COVID-19 vaccine is licensed for use in Canada under the Interim Order establishing a framework for importing, selling, and advertising drugs that are intended to be used with COVID-19. After September 16, 2021, Canadians will continue to have access to AstraZeneca Vaxzev
For optimal protection, this shot needs two doses.
Based on evidence from clinical trials, the dosing regimen recommended by Health Canada is to administer the two doses 4 to 12 weeks apart.
When getting the vaccine, your province or territory specifies when people should get their first and second doses.
Conformity to these policies is guided by public health guidelines and the most up-to-date evidence.
The vaccination is only intended for individuals over the age of 18. Its safety and efficacy in youngsters under the age of 18 have yet to be determined.
Clinical trials revealed that the Janssen COVID-19 vaccine was 66% effective in preventing COVID-19 disease after two weeks following the single dose.
A single injection is all that is required.
mRNA Vaccines
mRNA vaccines are a new generation of immunization. They do not utilize live viruses to induce an immune response. Instead, they instruct your cells to manufacture a protein that will stimulate an immune response. Your body produces antibodies as a result of the activation of these proteins. If the actual virus does enter your system in the future, these antibodies may help you.
mRNA vaccines have been the subject of research for quite some time. They’ve been researched for their use in flu, zika, rabies and cytomegalovirus (CMV), among other things. mRNA has also been used to stimulate the immune system to attack cancer cells.
The quick development of mRNA vaccines is due, in part, to the fact that they are produced in a laboratory using resources that are readily accessible. After completion, large-scale clinical trials are performed to demonstrate that the vaccine is both safe and effective.
Viral Vector Base vaccines
These vaccines are harmless viruses (in this case, the adenovirus) that is used as a delivery system in these vaccines.
Adenoviruses are viruses that cause the common cold. There are many different types, including ones that infect humans and species that infect other animals. These viruses have been used by researchers for decades to deliver protein-making instructions.
