Fresh speculation about President Vladimir Putin's health has reignited following Russia's announcement of a new cancer vaccine called Enteromix. The Kremlin has not confirmed any details about the president's medical condition, but discussions about potential treatments have put the spotlight on whether the Russian leader could be a candidate for this experimental therapy.
The vaccine was introduced publicly at the Eastern Economic Forum in Vladivostok in September 2025, where Russia's Federal Medical and Biological Agency (FMBA) described it as a major breakthrough in cancer treatment.
