He had his cake and ate it too. Took credit for the rapid development of the vaccine while playing on ignorance and superstition.
AI Overview
No, Donald Trump was not against the COVID-19 vaccine. He played a key role in its development through Operation Warp Speed, a program he launched in 2020 to accelerate vaccine creation and distribution. His administration also worked to ensure coverage and access to the vaccines for Americans, including seniors.  Trump himself received the vaccine and has publicly touted it as a success, stating in September 2025 that the vaccines “work. They just pure and simple work. They’re not controversial at all,” while emphasizing they should be used to prevent transmission and protect others. 
That said, his stance has included nuances and shifts over time:
• He has consistently opposed vaccine mandates, such as prohibiting federal funding for them in schools. 
• In more recent statements (e.g., September 2025), he has occasionally questioned their effectiveness and demanded pharmaceutical companies provide proof to “clear up this MESS,” while acknowledging that many view them as a “miracle that saved Millions of lives” but noting others disagree.  This skepticism appears tied to internal administration debates, including those involving figures like Robert F. Kennedy Jr., but Trump later reaffirmed support for the vaccines amid criticism of restrictions on access. 
Overall, Trump’s position has been supportive of the vaccine itself—taking credit for its rapid development—while criticizing mandates, boosters in some contexts, and calling for transparency on efficacy data.
