The debate reflected an international difference of opinion on the closely related virus strains. The World Health Organization recently issued guidance that last year’s version remained OK but that vaccine-makers could also choose an update, while the European Medicines Agency preferred that newer LP.8.1 subtype.While demand for vaccinations has dropped, the Centers for Disease Control and Prevention estimates 30,000 to 50,000 adults have died from COVID-19 since October. The virus continues to cause “enormous burden” on the health care system, CDC’s Dr. Fiona Havers told panelists. Older adults count for most hospitalizations and deaths but COVID-19 also is “a major cause of pediatric hospitalization,” especially in children under 2 — many of whom had no underlying medical problems before their infections.

The strain decision normally isn’t the final word on recommendations about who should be vaccinated.The CDC’s own advisory panel meets in June to make recommendations about the fall shots. Among its options are keeping universal access or recommending vaccination for high-risk groups but still giving lower-risk people the choice in getting a shot.CDC staffers presented real-world data Thursday showing that getting a booster last fall offered added protection even in people who had been infected and previously vaccinated. Company studies reached the same conclusion — including one by Moderna that compared medical records of about 900,000 people.

And not just to the roster — but “between the ears,” too.

Using the defending Stanley Cup champion Florida Panthers as an example, Treliving said at a season-ending news conference Thursday that there must be changes in the “DNA” of a team that continues to struggle in big playoff moments despite regular-season success.He is the fifth-youngest cricketer to become India’s test captain.

Keeper-batter Rishabh Pant has been named vice-captain for India’s tour of England.Jasprit Bumrah had been an option for the captaincy. He led India during the Border-Gavaskar Trophy — in the first test at Perth and then again in the final test at Sydney, where Sharma dropped himself. However, the pacer wasn’t chosen considering his fitness issues.

“We don’t think he will be available for all five tests — whether he plays three or four, we will see based on how the series goes and his workload,” Agarkar said. “We are happy he is part of the squad and have spoken with him. Jasprit understands the decision and his fitness. With him, it is about workload management.”Sharma, Kohli and Ravichandran Ashwin, who had also retired mid-series in Australia, are the key names missing from India’s squad. Karun Nair returns to the test fold to lend some experience and is expected to bat in the middle order.
