Former President Donald Trump and Health Secretary Robert F. Kennedy Jr. reignited controversy over COVID-19 vaccines this week, raising questions about transparency and effectiveness.
Kennedy, speaking on The Megyn Kelly Show, argued that mRNA vaccines such as Pfizer and Moderna show “negative efficacy” after seven months and accused public health agencies of using a “statistical trick” by counting early post-vaccination deaths as occurring among the unvaccinated.
Robert F Kennedy: "It's a trick".

One of the "little tricks" Big Pharma worked together with the government on.
Put any negative effects people had from mRNA 'vaccines' into the "unvaccinated" group. This hid vaccine injuries, deaths and gave the appearance the unvaccinated… pic.twitter.com/uD97xcbesU
In a recent interview, concerns were raised about the early effectiveness of COVID-19 vaccines such as Pfizer and Moderna. According to the claims, the vaccines are ineffective during the first six weeks after the initial dose, a period in which infection and death rates reportedly increase. Because official data do not classify individuals as “vaccinated” until two weeks after the second shot, any deaths occurring in that six-week window are attributed to the unvaccinated group — a practice described as a “statistical trick.”
The remarks further argued that while the vaccines provide noticeable immunity in the first one to two months, their protection declines rapidly. By the seventh month, effectiveness is said to drop into “negative efficacy,” meaning vaccinated individuals could become more likely to contract COVID-19 than those who never received the shots.
The claim suggests that this trend is consistent across multiple countries worldwide, though no peer-reviewed studies have confirmed this interpretation.Trump, once the chief advocate of Operation Warp Speed, echoed skepticism in a post on his Truth Social platform, demanding that pharmaceutical companies release full trial data. “I have been shown information from Pfizer, and others, that is extraordinary, but they never seem to show those results to the public,” Trump wrote, adding that the success or failure of the COVID response must be clarified “NOW.”
The shift is striking given Trump’s earlier praise of vaccines, and it comes amid turmoil at the Centers for Disease Control and Prevention. Reports of leadership shakeups within the agency coincide with Kennedy’s long-standing vaccine skepticism, despite scientific consensus that COVID-19 vaccines have prevented millions of deaths worldwide.
While calls for Nuremberg-style trials have surfaced among critics, no peer-reviewed studies support claims of mass vaccine-related deaths. Still, ongoing disputes over data transparency—highlighted by earlier delays in the release of Pfizer’s trial records—continue to fuel public distrust and political division over the pandemic’s legacy.
