Häufig Gestellte Fragen

1Is Pfizer Bivalent Approved In Canada?

the Pfizer bivalent vaccine is not yet licensed in Canada and when it will be available is unknown; once it is available, the Department of Health and Wellness will communicate this publicly.

2Are Covid-19 Vaccines Effective?

COVID-19 vaccines authorised for use in the EU/EEA have been very effective at preventing severe disease, hospitalisation and death.
In general, benefits of COVID-19 vaccines may include:
– preventing SARS-CoV-2 infection in vaccinated individuals
– reducing disease severity, if vaccinated individuals are infected
– preventing death in vaccinated individuals
– reducing the number of people infected in populations with adequate vaccine uptake
– reducing virus transmission in populations with adequate vaccine uptake.

3What Is Herd Immunity In Terms Of Covid-19?

Herd immunity’, also known as ‘population immunity’, is the indirect protection from an infectious disease that happens when a population is immune either through vaccination or immunity developed through previous infection. WHO supports achieving ‘herd immunity’ through vaccination, not by allowing a disease to spread through any segment of the population, as this would result in unnecessary cases and deaths.

4Is Covid-19 Vaccination Still Necessary, Even After Getting Infected With The Virus And Recovering?

Evidence is growing that vaccination after infection strengthens protection and further reduces the risk of reinfection. Therefore, COVID-19 vaccination is generally recommended for the eligible population, including those who have recovered from the disease.

5Will Covid-19 Vaccines Stop The Pandemic?

It is likely that SARS-CoV-2, the virus that causes COVID-19, will continue to circulate and evolve. It is not possible to predict how infectious or severe new variants of the virus will be. It is therefore very important to achieve and maintain high vaccination coverage across all communities and population groups, at national and international levels. Vaccination remains a key component of the multi-layered approach needed to reduce the impact of SARS-CoV-2.

6How Do We Achieve Herd Immunity Against Covid-19?

To safely achieve herd immunity against COVID-19, a substantial proportion of a population would need to be vaccinated, lowering the overall amount of virus able to spread in the whole population.
