Question Your World: How Effective Is the Johnson & Johnson Vaccine?
Humanity now has a few tools to helping address the novel coronavirus pandemic. Here in the United States the FDA has three vaccines now authorized for emergency use. The latest vaccine offering is made possible by the Johnson & Johnson (J&J) company. This new vaccine has been making headlines for a few different reasons, but the big question on everyone’s mind is how effective is the J&J vaccine?
On February 27, 2021, the FDA issued an emergency use authorization for the Johnson & Johnson COVID-19 vaccine, making it the third vaccine available now! So, let’s take a moment to explore this new vaccine, how it works, and examine its effectiveness.
First of all, this new J&J vaccine works with only a single dose, meaning no follow ups for round two like the other options currently available. This vaccine is also easier to ship and store: it can be kept at simple refrigerator temperatures for up to three months!
The J&J team is also using a different technology in this vaccine. Theirs uses a weakened virus that cannot infect you to deliver genetic instructions to your cells to produce the novel coronavirus' spike protein. Your immune system responds, remembers this spike protein, and – just like that – you’re protected.

But the big question on everyone’s mind is how effective is this new single-dose vaccine?
Short answer: very effective.
Long answer: very very effective! This vaccine’s trials revealed an 85% efficacy in preventing severe COVID-19 illness. Also, like the other vaccines, the J&J vaccine provided 100% protection against hospitalization and death from COVID-19. Medical experts observed that this level of protection against moderate to severe disease starts only two weeks after the single dose J&J vaccine.
The side effects observed during trials were mild injection site pain, fatigue, muscle and joint pains, and headache. There were a few reported fevers. These are similar to the side effects of your annual flu shot. This new J&J vaccine now joins the Moderna and Pfizer options as safe, effective protections against COVID-19, and incredible achievements of modern science.
Experts emphasize that you should take any of the vaccine options given to you because they all do the same thing: keep you protected from COVID-19! Remember, it’s only after everyone who can get vaccinated does get vaccinated that we can safely loosen social distancing restrictions and begin to resume interactions with friends and loved ones. Thanks to science we now have three options to help protect us from the reach of this virus.
