Plenity is the first ingested, transient, space-occupying hydrogel to be marketed in the US and the only weight management treatment available by prescription for patients with a BMI of 25-30 kg/m2, regardless of...

The CDC has issued new guidance allowing for an interval of up to 8 weeks between the first and second primary doses of an mRNA COVID-19 vaccine in certain patients 12-64 years old.1 Product labeling currently recommends a 3-week interval between the first two doses of the Pfizer/BioNTech mRNA vaccine (Comirnaty) and a 4-week interval between the first two doses of the Moderna mRNA vaccine (Spikevax). The new guidance is based on data suggesting that a longer interval can decrease the risk of myocarditis and may improve vaccine efficacy.
