We are pleased to announce that most of our staff members have been vaccinated, in accordance with the Ontario Ministry of Health. This will protect our staff and patients considerably from COVID-19 virus transmission.
The following facts put forward by the WHO will answer a few concerns generally raised regarding COVID vaccines.
The impact of COVID-19 vaccines on the pandemic will depend on several factors. These include the effectiveness of the vaccines; how quickly they are approved, manufactured, and delivered; the possible development of other variants and how many people get vaccinated
Whilst trials have shown several COVID-19 vaccines to have high levels of efficacy, like all other vaccines, COVID-19 vaccines will not be 100% effective. WHO is working to help ensure that approved vaccines are as effective as possible, so they can have the greatest impact on the pandemic.
The COVID-19 vaccines produce protection against the disease, as a result of developing an immune response to the SARS-Cov-2 virus. Developing immunity through vaccination means there is reduced risk of developing the illness and its consequences. This immunity helps you fight the virus if exposed.
Several different types of potential vaccines for COVID-19 are in development, including:
Inactivated or weakened virus vaccines, which use a form of the virus that has been inactivated or weakened so it doesn’t cause disease, but still generates an immune response.
Protein-based vaccines, which use harmless fragments of proteins or protein shells that mimic the COVID-19 virus to safely generate an immune response.
Viral vector vaccines, which use a safe virus that cannot cause disease but serves as a platform to produce coronavirus proteins to generate an immune response.
RNA and DNA vaccines, a cutting-edge approach that uses genetically engineered RNA or DNA to generate a protein that itself safely prompts an immune response.

The COVID-19 vaccines produce protection against the disease, as a result of developing an immune response to the SARS-Cov-2 virus. Developing immunity through vaccination means there is a reduced risk of developing the illness and its consequences. This immunity helps you fight the virus if exposed. Getting vaccinated may also protect people around you, because if you are protected from getting infected and from disease, you are less likely to infect someone else.
Currently, there is no evidence that any other vaccines, apart from those specifically designed for the SARS-Cov-2 virus, will protect against COVID-19.
Ensuring the safety and quality of vaccines is one of WHO’s highest priorities. WHO works closely with national authorities to ensure that global norms and standards are developed and implemented to assess the quality, safety and efficacy of vaccines.
There are many strict protections in place to help ensure that COVID-19 vaccines are safe. Like all vaccines, COVID-19 vaccines are going through a rigorous, multi-stage testing process, including large (phase III) trials that involve tens of thousands of people. These trials are specifically designed to identify any common side effects or other safety concerns.
