While US FDA and CDC advisory panels recommended a Pfizer booster jab for certain groups last week, some panelists said a J&J booster should be the focus, NPR reports.
 
Concerns about Pfizer’s waning vaccine effectiveness for those 65+ sparked the booster discussion, but J&J’s protection against hospitalization has dropped to 71%—roughly same level as Pfizer’s. Some doctors are giving Pfizer booster shots to those at high risk who had a single shot of the J&J. Other docs may recommend a second J&J jab.
 
The FDA is reviewing early J&J data that show a second shot increases protection against severe disease.
