Trump's Vaccine Plan Hit with Reality Check: No Standalone Vaccines Available

President Donald Trump's latest health plan aimed at separating measles, mumps, and rubella vaccines has hit a significant hurdle. The administration wants to replace the combined MMR vaccine with three separate injections once individual products become available in the United States.

However, medical experts and manufacturers say bringing those products to market would likely take years, even if companies decided to pursue them. Merck stopped producing standalone measles, mumps, and rubella vaccines in 2008, leaving only combination MMR vaccines available.

Both Merck and GSK currently manufacture the combined vaccine used across the country, and they pointed out that there is no scientific evidence supporting the separation of the vaccines. They also warned that creating standalone versions would be a lengthy process, taking potentially as many as 10 years to meet safety and efficacy requirements for FDA approval and then begin manufacturing and commercialization.

Experts agree with this timeline, saying developing three separate vaccines would involve far more than changing existing production lines. Each vaccine would require independent testing, regulatory approval, and manufacturing capacity before becoming available.
