  • Pfizer clinical trial data reveals the company’s Covid vaccine has a 12% efficacy rate, reads the headline on what seems to be a screenshot of an article by the Canadian news website Global News, circulating on social media since May 2022. It shows a generic photo of a row of Covid-19 vaccines with the Pfizer logo behind them. Text below reads: Despite claims from Pfizer CEO Albert Bourla and countless public health officials that the efficacy of the vaccine was nearly 100%, the findings of the company’s clinical trial data show it was less than 12%. The Pfizer-BioNTech Covid vaccine is used in at least 179 countries . In South Africa, about 27.7 million doses of the vaccine – first, second and booster shot – have been administered. But did Global News really publish an article revealing that Pfizer’s own data found its vaccine had an efficacy rate of less than 12%? We investigated. Article ‘never published on our site’ A Google search for the screenshot's headline returned no Global News articles. We searched the site itself and again came up empty . What we did find was a Global News article from November 2020 with the headline: Pfizer says final results show coronavirus vaccine is 95% effective, no safety concerns. A Global News spokesperson told Reuters that the site had not published the article. We can confirm that the headline and caption in question were never published on our site and they are falsely associated with the Global News brand. The screenshot is fake. But what about the claim about the Pfizer-BioNTech vaccine’s efficacy? Efficacy of 95% – but booster shot still needed The Pfizer BioNTech vaccine against Covid-19 has an efficacy of 95% against symptomatic Sars-Cov-2 infection, the World Health Organization (WHO) says. Sars-Cov-2 is the coronavirus that causes Covid-19. The vaccine is proven safe, the WHO says, and significantly reduces Covid hospitalisations and deaths. In February the US Food and Drug Administration gave emergency authorisation for the Pfizer-BioNTech vaccine to be given to children aged six month to under four years. The jab has an efficacy rate of 80.3% in this age group. Yale University in the US explains that while the two-dose vaccine does have an efficacy rate of 95%, its protection wanes over time. So it’s important that adults get a third booster shot, which brings the immune system back to robust level, the university says. (en)
