Acting CDC Director Jim O'Neill is calling for the measles, mumps and rubella vaccine to be split into three separate shots. It comes as the CDC approves new guidelines for updated COVID vaccines.

Washington

The acting director of the CDC has suggested splitting the combined measles, mumps, and rubella (MMR) vaccine into three separate shots. Medical experts, including Dr. Selene Gounder, have expressed concerns about this proposal, noting there is no high-quality evidence that separate shots would be safer or more effective. They also highlighted logistical challenges, such as the lack of single-disease vaccines in the United States and the increased burden on families and healthcare providers.

Additionally, the CDC has updated its COVID-19 vaccine guidelines, moving away from recommending annual boosters for everyone. The new approach focuses on individual risk assessment. Experts warn this could impact insurance coverage and vaccine availability, especially since a significant portion of Americans do not have a primary care provider to guide them on vaccination decisions.

The significance of splitting up the MMR vaccine into separate shots

Today, the acting director of the CDC called for upending how children have been protected against measles, mumps, and rubella for the last 50 years. Jim O'Neill said he was calling for the MMR vaccine to be split into three separate shots. This comes as the CDC finally approved new guidelines for updated COVID vaccines. Joining me now, CBS medical contributor, Dr. Selene Gounder. Okay, Dr. Gounder, let's start with the MMR vaccine. Split them up. What does that mean? Is there an upside or a downside to that? So MMR, it stands for measles, mumps, and rubella. The short answer to whether it makes sense to split up these vaccines is no. And I think it's important to note that the acting CDC director is not a doctor, not a healthcare worker, not a scientist, he's a lawyer, but there is no high quality data to show that this would be safer or more effective than what we already do now. It would mean more appointments, more needle sticks for kids and fewer kids completing the full series. And on top of that, we actually don't have these vaccines, these single disease vaccines here in the United States. So it's just not a logistically feasible kind of thing to be doing. Wow, all right. I wanna make sure I don't lose you on COVID. So what's the new guidance? What was said about COVID? So we're moving away from the recommendation everybody needs a booster every winter. So it's instead of a blanket approach, it's more of a individualized risk-based approach. The catch here is that insurance coverage is also contingent on these recommendations. So some insurance companies could decide no longer to cover COVID vaccinations. And then retail pharmacies may not order as much vaccine for everybody who would normally perhaps want a vaccine. And finally, a third of Americans don't have a primary care provider, so may not even know if they have underlying conditions that put them at higher risk for severe COVID. So because you're supposed to talk to a doctor, if you don't go to your doctor. If you're one in three Americans who doesn't have a doctor to talk to about this, I don't quite know how you're gonna get that information.
