• The Centers for Disease Control and Prevention yesterday declared the outbreak of infant botulism linked to powdered formula over. Epidemiologic, traceback, and laboratory data indicate the cause of the outbreak, which led to four infant hospitalizations in three states, was contaminated Nara Organics Whole Milk Organic Infant Formula.

The Food and Drug Administration (FDA) says data indicate the milk used in the formula came from the same supplier implicated in a 2025 infant botulism outbreak linked to infant powdered formula.
• The FDA announced yesterday that it has issued an emergency use authorization for Bimectin, an injectable form of ivermectin, for the prevention of New World screwworm (NWS) infestations in cattle. The FDA says all available scientific data suggest Bimectin—when administered within 24 hours of birth, at the time of castration, or at the appearance of a wound—may be effective at preventing NWS myasis. There have been 46 confirmed detections of NWS in cattle and sheep in Texas since June 3, and one case in a dog in New Mexico.
• Two airport workers in Germany have died after contracting malaria from an Anopheles mosquito transported by plane, and four others have been hospitalized, German health officials said this week. Public Health Authority Frankfurt says it’s investigating the incident, and that mosquito traps have been set up at Frankfurt Airport to monitor for possible occurrences of disease-carrying mosquitoes.

The Food and Drug Administration (FDA) has approved updated COVID-19 vaccines from Moderna, Novavax-Sanofi and Pfizer-BioNTech. All three vaccines are designed to prevent severe disease caused by the dominant strain, the JN.1 lineage XFG subvariant.

The FDA approved the vaccines for adults 65 and older, as well as younger people with one or more chronic conditions that put them at higher risk for severe disease, the companies announced yesterday.

Each vaccine approval is slightly different.

• Pfizer’s mRNA vaccine, Comirnity XFG, is approved for adults 65 years and older, and people ages 5 to 64 years old with an underlying condition. Pfizer said in a press release that it has already begun distributing vaccines, and that they should arrive in pharmacies soon.
• Moderna’s mRNA vaccine, Spikevax, is approved for people age 65 and older, and those 6 months to 64 years old with an underlying condition. Moderna’s new, lower-dose vaccine, mNEXSPIKE, is approved for people age 65 and older, as well as people 12 to 64 years old with an underlying condition.
• Sanofi also has received FDA approval for its COVID-19 vaccine, Nuvaxovid, originally licensed by Novavax, which does not use mRNA technology. Nuvaxovid is approved for adults ages 65 years and older, and people ages 12 years to 64 years who are at high risk for severe COVID-19.

Many conditions can increase the risk of developing a severe case of COVID-19, according to the Centers for Disease Control and Prevention (CDC). These include asthma, cancer, chronic lung or kidney disease, mental illness, obesity, pregnancy, and smoking.

According to the CDC, cases of COVID-19 are “growing or likely growing” in 48 states.

Most insurance plans will cover the updated shots

AHIP, an organization that includes most health insurers, has said that its members will cover the total cost of vaccines recommended by a CDC committee at least until the end of 2027. 

CVS, one of the country's largest drugstore chains, is currently advertising “free COVID-19 vaccines with most insurance,” but notes that appointments may be unavailable in some states.
