Unlike Pfizer‘s and Moderna‘s vaccines, J&J’s one-dose routine eliminates the want for sufferers to return for a second dose and it could well perhaps perhaps goal also be saved at refrigerator temperatures for months.
J&J’s vaccine “makes it operationally more straightforward in hundreds contexts,” Dr. Nancy Messonnier, director of the CDC’s Nationwide Heart for Immunization and Respiratory Ailments, told the Journal of the American Clinical Association sooner or later of a Q&A match on Friday. “I demand hundreds considerations insist health departments are having around these vaccines is extra in regards to the benefit of use of the J&J vaccine and the diagram it could well perhaps well be greater suited for some populations.”
