Novavax Inc. is still waiting for U.S. regulators to decide whether to authorize its COVID-19 vaccine, which some experts believe could serve as an alternative option for people who are hesitant to get a mRNA vaccine. Novavax’s vaccine, called Nuvaxovid, is a recombinant protein-based shot that is similar in design to a flu shot that’s been available in the U.S. since 2013. This type of vaccine has a different makeup than the mRNA vaccines developed by Moderna Inc., BioNTech and Pfizer Inc., as well as the adenovirus shot from Johnson & Johnson. (Lee, 5/26)

There were close to 40 million plasma donations in the United States in 2017. Many people who regularly donate plasma know how important their donations are for use in lifesaving medical treatments. Some have raised questions about plasma donation during the coronavirus 19 (COVID-19) pandemic. For instance, if you’re a regular donor, you’ll likely have heard false reports that you won’t be able to donate if you get a COVID-19 vaccination. (Behring, 5/26)

Long-lasting yet flagging protection conferred by a previous COVID-19 infection or vaccination can be reinforced by even a single vaccine dose, concludes an Israeli study published yesterday in NEJM.A team led by researchers from the Technion-Israel Institute of Technology in Haifa mined the Israeli Ministry of Health database for data on all patients who tested positive for COVID-19 or received any dose of the Pfizer/BioNTech vaccine from August to September 2021, when the Delta variant was dominant.

A letter yesterday in the New England Journal of Medicine (NEJM) from Centers for Disease Control and Prevention scientists shows homologous (same-vaccine) boosting for Johnson & Johnson (J&J) vaccine recipients was significantly less effective than mix-and-match booster doses when the Omicron strain was predominant in the United States. Approximately 18 million Americans received the one-dose J&J vaccine as their primary COVID-19 vaccine. The study tracked COVID-19 cases among J&J recipients with no booster, a J&J booster, an mRNA booster, and adults who received three doses of mRNA vaccine (a primary series plus a booster). (5/26)
