The delay, narrowed approval, and extra study steps raise concerns about the status of and potential added requirements for other COVID vaccines.

A study in Ontario suggests that, compared with a third dose of mRNA COVID vaccine, a fourth dose improved protection against infection and severe outcomes among long-term care residents during the Omicron wave. The study was published today in The BMJ.
BA.5 now makes up 53.6% of cases, BA.4 makes up 16.5%, and both are highly transmissible.
The odds of having long COVID fell from 48% before vaccines to 16% after a third vaccine dose.
A new study shows that the proportion of children diagnosed as having COVID-19 and croup was significantly higher during the Omicron surge than in earlier waves dominated by other variants.
Croup is an upper airway infection generally affecting children. It causes swelling around the larynx, trachea, and bronchi, resulting in labored breathing and a "barking" cough.
Though all benefited, those at lowest and highest body weights were at greater risk, possibly due to differences in immune response.
The mobile units are geared toward reaching high-risk communities and come as the US and other countries battle rising COVID activity.
A study of children hospitalized with community-acquired pneumonia (CAP) suggests that antibiotic decisions made in the emergency department (ED) have a significant impact on inpatient antibiotic use, researchers reported today in Pediatrics.
The study also found that nearly a third of children without radiographic evidence of pneumonia received antibiotics, suggesting that overuse is common.
Findings were similar to adults, but testing policy changes limited the study's ability to assess longer term impact.
Following a vaccine advisory group input earlier this week, the Food and Drug Administration (FDA) today recommended that vaccine companies update their booster shots to target BA.4 and BA.5, two Omicron subvariants that are driving up cases in a number of countries.
Deaths may have been directly related to COVID-19 or exacerbated by COVID-19 or by healthcare disruptions, study authors say.
