The new vaccine created by Johnson and Johnson has significant differences from Moderna and Pfizer's vaccines, but they all do the same thing - fight coronavirus infections.
"It offers us one dose and the fact that it has much easier logistical requirement and storage requirements," said Keith Reed. Deputy Commissioner of Health.
Johnson and Johnson's COVID-19 vaccine only requires one dose and can be stored in a normal refrigeration.
But health officials say you should get whatever shot is available.
"One is better than none," said Douglas Drevets with OU Health.
Trials showed the Johnson and Johnson vaccine has 66% efficacy meaning two out of three people who got the shot got infected with COVID-19 and never got sick.
That is far lower than Moderna and Pfizer's vaccines which have 90 percent efficacies.
"You have to keep in mind our annual flu vaccine is around 50-60% effective," said Dr. Drevets. "The Johnson and Johnson vaccine was around 85- 90% effective of preventing hospitalizations."
Another big difference the Johnson and Johnson vaccine does not cause an allergic reaction, and people who got the shot showed fewer side effects like arm pain and fatigue.
Health care officials are still awaiting the advisory committee on immunization practices for this Janssen vaccine. They are expected to release their recommendations later this week.
