POTSDAM, N.Y. (WWNY) - The chief medical officer of St. Lawrence Health System says the new Johnson & Johnson vaccine against COVID is effective.
“It’s 85-percent effective at preventing serious illness, and it was 100-percent effective at preventing hospitalization and death,” said Dr. Andrew Williams.
Unlike the Moderna and Pfizer vaccines, Johnson & Johnson is a one shot vaccine which can be stored in normal refrigeration.
The Johnson & Johnson vaccine is effective after about 28 days.
Studies in the U.S. have shown the vaccine to be 72-percent effective against COVID-19, lower than Pfizer and Moderna, though some experts have suggested that may be because of when Johnson & Johnson tested the vaccine - during a period of high infection - which could make the vaccine falsely appear to be less effective.
Dr. Williams says whichever vaccine you’re offered first you should take, and you should take it with confidence.
St. Lawrence Health System operates Canton-Potsdam Hospital, Gouverneur Hospital and Massena Hospital.
