Trump's vaccine separation order may limit access, not expand choice
A sociologist studying Colorado parents finds separating MMR shots could reduce vaccine access despite intent to offer flexibility.
What to know
- Trump's August 2026 executive order calls for separating MMR vaccine components based on unsubstantiated claims that combined vaccines are dangerous.
- CDC and scientific evidence show no benefit to separating the vaccine; the combined version has a long safety record since 1971.
- Separating shots may reduce access for families struggling with costs and clinic visits, contrary to the order's stated goal of expanding parental choice.
- Colorado's measles vaccination rate of 87.7% in kindergarteners falls below the 95% threshold needed for community immunity, ranking sixth-lowest nationally.
“No published scientific evidence shows any benefit in separating the combination MMR vaccine into three individual shots, according to the CDC.”

Colorado measles vaccination rate falls below herd immunity threshold
During the 2025-26 school year, about 87.7% of Colorado kindergartners had received both measles shots, giving Colorado the sixth-lowest vaccination rate in the country. This falls far below the 95% threshold needed to achieve community-wide immunity against measles.

Separating MMR vaccines into individual shots sounds like giving parents more choice, but it could actually limit access for families already struggling with healthcare costs and getting to a clinic.

background
CDC confirms no scientific benefit to separating MMR vaccine — According to Reich's analysis, the CDC has found no published scientific evidence showing any benefit in separating the combined MMR vaccine into three individual shots. The vaccine has been given in combination since 1971 and became the only option around 2008, with evidence the combination may even yield a stronger immune response.

Sociologist: separation order could reduce vaccine access — Jennifer Reich, a University of Colorado Denver sociology professor who has spent nearly two decades studying vaccine decisions, published analysis finding that separating MMR components may actually limit parents' access to vaccines. While the order sounds like expanded choice, it could create barriers for families facing healthcare costs and clinic logistics.

background
Trump signs vaccine separation executive order — President Donald Trump signed an executive order on vaccines that calls for measles, mumps, and rubella vaccine components to be given separately rather than in combination. Trump claimed at the signing that combined MMR vaccines could be "quite lethal" and that separate shots would be "not at all lethal but just very effective."
