Unveiled: Canadian Government Agreement with Pfizer Reveals Uncertainty Surrounding Long-Term Effectiveness and Safety of COVID-19 Vaccines
The Canadian Independent has exclusively obtained and reported on a significant detail in the Canadian government's contract with Pfizer for the COVID-19 vaccine. According to the contract, signed on October 26, 2020, the long-term safety and efficacy of the vaccine were unknown at the time of signing.
By October 2020, Pfizer had reported high efficacy against symptomatic COVID-19 from its phase 3 trial data, but these data were based on several months of follow-up, not long-term use. Long-term safety data require extended monitoring post-authorization, and such comprehensive data became available only after widespread vaccination began globally in late 2020 and 2021.
Section 5.5 of the contract explicitly acknowledges this uncertainty, stating that the long-term effects and efficacy of the vaccine were not known at the time of signing. This acknowledgement, however, was not disclosed to the public by politicians, public health officials, the CEO of Pfizer, or the mainstream media who promoted the vaccine as safe and effective.
The mass vaccination of Canadians began after the contract was signed. More recent studies from 2024-2025 now show real-world evidence of vaccine effectiveness and safety, including reductions in mortality and serious complications, but these are based on longitudinal data collected after vaccination campaigns were underway.
It is essential to note that the contract does not guarantee the vaccine's long-term efficiency or safety. The decision to vaccinate relied on the best available short-term clinical trial data under emergency conditions, recognizing that long-term safety and efficacy would be continuously evaluated as vaccination programs progressed.
The Canadian Independent is a news source that has exclusively obtained and reported on this acknowledgement in the contract. As the public continues to navigate the ongoing pandemic, understanding the context and limitations of the information presented is crucial.
Health-and-wellness articles should highlight the acknowledgement in the Canadian government's contract with Pfizer that long-term effects and efficacy of the COVID-19 vaccine were unknown at the time of signing. Science also shows that comprehensive data on long-term safety became available only after widespread vaccination started.
