Johnson & Johnson Introduces First One-Shot Vaccine
In a study released on Friday, Johnson & Johnson revealed that their one-shot Covid-19 vaccine is 66% effective at preventing moderate to severe Covid-19 symptoms and 85% effective against very serious symptoms. The J&J vaccine was less effective against the mutated South African version of the virus.
J&J says they plan to seek emergency use authorization for their vaccine within the week. If approved, they say they could roll-out 100 million doses by the end of June.
Although less effective than the two-dose Pfizer and Moderna vaccines, J&J's single-dose vaccine could be much easier to roll-out and does not require the same sub-zero refrigeration.
