Shortly after checking on with ZMA; Miami Center we began getting comm interference on 126.52.  The voice appeared to be a recording outlining information / disinformation about the COVID-19 vaccine (it may have been a live reading; but the cadence made it seem like a recording).  We notified Center; who in-turn seemed to boost their output power which momentarily helped. Within minutes the recording was again dominating the frequency. Comms were barely readable; frequency changes had to be read back multiple times by several aircraft. The interference signal seemed to be strongest as we passed 30 NM east of TPA on Q118 heading north.  Once we were switched to ZJX; JAX Center we had no more problems.
Air carrier Captain reported hearing non-aviation information on a ZMA 126.52 frequency interfering with regular communications.
