How far can health secretary Robert F. Kennedy Jr. go in remaking public health policy in his image? Could he, say, call on Americans to maximize their exposure to measles in a bid to reach herd immunity? The Department of Justice seems to think so. In defending the health secretary’s changes to the childhood vaccine schedule and to the federal vaccine advisory committee in federal court on Wednesday, government lawyers said that Kennedy and other health officials have broad discretion to issue such guidance — and to choose the kinds of evidence to consider and the experts to consult. (Oza, 3/4)

In other vaccine news —

Scientists from institutions across the US have now developed a strikingly "universal" vaccine, which has protected mice against a range of viruses, bacteria, and even allergies. The new GLA-3M-052-LS+OVA vaccine can be delivered as a nasal spray. Three doses protected mice from infection from SARS-CoV-2 and other coronaviruses for three months, and reduced the viral load in their lungs 700-fold, compared to unvaccinated mice. (Irving, 3/4)

On the spread of flu and measles —

Now that SARS-CoV-2 is no longer a novel virus sweeping through a population with little immunity, covid and influenza illnesses are becoming more similar, with a key difference: Coronavirus circulates year-round and ticks up in the summer, when flu is gone. Does that mean flu is now the woe of the winter, and covid is the scourge of the summer? It’s complicated and too soon to say. “We don’t know where covid is going. I really don’t think we know what is the next season going to look like,” said Manisha Juthani, Connecticut’s top public health official and president of the Association of State and Territorial Health Officials.
