How Johnson & Johnson’s coronavirus vaccine compares to different vaccines obtainable – CBS Pittsburgh

PITTSBURGH (KDKA) – The Johnson & Johnson vaccine is now the third coronavirus vaccine in the United States to be approved in the event of an emergency.

“This should really help with the spread and get closer to the end of the pandemic,” says Dr. Matthew Moffa, Infectious Disease Physician, Allegheny Health Network.

It is different from the Pfizer and Moderna vaccines. For example, J & J’s is not an mRNA vaccine.

“It’s something like a viral vector vaccine,” said Dr. Moffa. “So it takes a harmless virus called adenovirus that has been inactivated in the lab, and they wrap it up with genetic information.”

Genetic information for the coronavirus spike protein, which the body begins to produce and which stimulates the immune system to produce antibodies.

“If you are exposed to the virus in the future, your body will be ready to offer you protection,” said Dr. Moffa.

Johnson & Johnson’s vaccine has advantages.

“It only takes one shot and after 28 days you are considered completely immune,” said Dr. Moffa. “We saw the most common things like arm pain, fatigue, muscle pain, but to a lesser extent than the other two.”

“All that is required is standard cooling to help make it available in doctors’ offices, clinics and pharmacies,” he added.

In studies, it was 66 percent effective worldwide and 72 percent in the United States. While this appears to be inferior to the 95 percent in either the Pfizer or Moderna recordings, it is actually much better than the established standard.

“The FDA wanted it to be over 50 percent effective, which it was,” said Dr. Moffa.

“The Pfizer and Moderna vaccines were studied at a time before these new variants hit the market,” he added.

They are all comparable where it matters most.

“It was 100 percent effective at keeping people out of the hospital and keeping them alive,” said Dr. Moffa.

Of course, people have questions about which vaccine to take.

“All three are highly effective, highly safe, and you should be thrilled to take the vaccine that is offered to you,” said Dr. Moffa.
