The Mohawk Council of Akwesasne’s Department of Health (DOH) is providing the community with an update on the COVID-19 vaccine’s efficacy, and effectiveness against Variants of Concern (VOCs). 

mRNA vaccines (Moderna and Pfizer) have an estimated efficacy of 94-95% 14 days after full vaccination (having received both doses). Studies are ongoing to gauge the exact effectiveness of the vaccines to the variants of COVID-19, however, trials have shown the vaccines are highly effective against infection and illness. 

According to the National Advisory Committee on Immunization of Canada (NACI), the effectiveness of the Moderna and Pfizer vaccines against Variants of Concern (VOCs) continues to evolve. There is evidence that both Pfizer and Moderna have proven effective against the UK variant (B.1.1.7), the India variant (B.1.167.2), and the South Africa variant (B.1.351). Data is currently limited regarding the vaccines and their effectiveness against the Brazil variant (P.1 and P.2). 

After six months of being fully vaccinated, a study on the Pfizer and Moderna COVID-19 vaccines has shown to have a 91.3% or greater efficacy against the COVID-19 virus, and 100% effective against severe disease. At this time, it is not known if a third booster, or annual inoculation will be required.  

It is still possible to become COVID-19 positive even after being fully vaccinated, but these cases have been rare. It is still highly recommended that you wear a mask and practice physical distancing when out in public, and adhere to public health guidelines. 

If you have any questions about the COVID-19 vaccines, or to register for the community vaccine clinics, please call the Community Health Program at 613-575-2341 ext. 3220.
