Deaths from disease are first in state in 35 years and just one day after Maryland declared outbreak in three counties

Two unvaccinated individuals have died of measles in Pennsylvania, state health officials announced on Tuesday. The deaths are the first in the state in 35 years and have been announced just one day after Maryland declared a measles outbreak in three counties.

Measles is one of the most contagious diseases known to medicine, and is preventable with a highly effective vaccine.

New CDC data shows MMR vaccination among kindergarteners declining slightly as non-medical exemptions climb to 4.2%

A week after Donald Trump made a series of misleading claims about vaccines – including that some injections look “like the size of a soda bottle” – the Centers for Disease Control and Prevention (CDC) released the latest data on national kindergarten vaccination rates.

CDC communications downplayed the changes – a three-sentence announcement said, “overall vaccination rates among kindergarteners remained high” – but medical experts immediately saw cause for concern in the trends.

The president’s empty advice that children should receive separate jabs against measles, mumps and rubella will only lead to less take-up by parents

Nobody wants to hurt a child. The howl of pain, the tears, the look of betrayed shock all make it very hard to deliver a cherished small person to the needle-wielding nurse. But that’s part of being a responsible parent. It becomes a lot tougher if mum or dad is being fed mixed and erroneous messages about the benefits and harms of vaccination.

Parents have to make a lot of decisions about what’s right for their child, from the school they should go to and the food they should eat to the hours they should spend on the phone or watching TV. In the US, Donald Trump wants them to add another: do they choose to give their children separate jabs against measles, mumps and rubella, involving six visits to the clinic, or should they opt for the combined MMR vaccine, which does the job in two? For decades, the vast majority of families have been taking the advice of doctors, accepting their assurance that the MMR vaccine is safe and very effective. But what are they to think when a US president announces that the triple jab could be “quite lethal” and signs an executive order advising states to offer separate vaccines?

Outgoing Louisiana senator Bill Cassidy, a medical doctor, voted to confirm anti-vaccine activist RFK Jr as health secretary before speaking out

The Republican senator Bill Cassidy – a medical doctor who voted to confirm anti-vaccine activist Robert F Kennedy as federal health secretary in early 2025 – on Sunday denounced Donald Trump’s “crazy, stupid” claims about the safety of the combined MMR vaccine for undermining faith in immunization.

When Trump recently ordered changes to the recommended childhood vaccination schedule, with Kennedy by his side, the president called for two shots of the combined measles, mumps and rubella vaccine to be scrapped in favor of two doses of three separate vaccines, claiming that the MMR shots are “sort of like a nuclear weapon” that could be “quite lethal”.
