Johnson & Johnson vaccine

The Johnson & Johnson vaccine, also known as the Janssen vaccine, is a single-dose COVID-19 vaccine that was authorized for emergency use in the United States in February 2021. It differs from the Pfizer-BioNTech and Moderna vaccines, which require two doses.

The Janssen vaccine uses a different technology called viral vector to deliver instructions to cells to make a harmless piece of the virus that causes COVID-19. This piece, called spike protein, triggers an immune response that protects against future infections. The viral vector used in the Janssen vaccine is a modified version of adenovirus, a type of virus that can cause the common cold. This adenovirus cannot replicate or cause illness, but it helps the body recognize and fight COVID-19.

Clinical trials have shown that the Janssen vaccine is highly effective at preventing severe COVID-19, hospitalization, and death in people aged 18 years and older. In a large study of more than 43,000 participants, the Janssen vaccine was found to be 66.3% effective at preventing moderate to severe COVID-19, 85% effective at preventing severe COVID-19, and 100% effective at preventing hospitalization and death.

Like other COVID-19 vaccines, the Janssen vaccine can cause side effects, although they are generally milder and less frequent than those associated with mRNA vaccines. The most common side effects include pain, swelling, and redness at the injection site, as well as fever, fatigue, headache, muscle aches, nausea, and chills. These side effects typically occur within one to three days after vaccination and resolve on their own within a few days. Serious side effects are rare but may include blood clots or low platelet count, especially in women under 50 years of age.

Overall, the Janssen vaccine offers a convenient and effective option for people who prefer a single-dose vaccine or have difficulty returning for a second dose. However, it is important to discuss any concerns or medical conditions with a healthcare provider before getting vaccinated.
