Johnson & Johnson COVID-19 Vaccine Fact sheets

 

FSU has received 800 doses of the Johnson & Johnson vaccine, available to students. Vaccine Type: Viral Vector, 1 shot--delivered in the muscle of the upper arm. How Well the Vaccine Works: According to the World Health Organization, a dose of Johnson & Johnson was found in clinical trials to have an efficacy of 66.9% against symptomatic moderate and severe Covid-19 infection. 28 days after inoculation, it was found to have an efficacy of 85.4% against severe disease and hospitalization. How Does Johnson & Johnson work? Viral vector vaccines use a modified version of a different virus (the vector) to deliver important instructions to our cells. The benefit of viral vector vaccines, like all vaccines, is those vaccinated gain protection without ever having to risk the serious consequences of getting sick with COVID-19. JOHNSON & JOHNSON (OR ANY OTHER VACCINE) CANNOT GIVE YOU THE DISEASE ITSELF. Possible Side Effects: In the arm where you got the shot--Soreness, Redness, Swelling. Throughout the rest of your body--Tiredness, Headache, Muscle pain, Chills, Fever, Nausea. These side effects usually start within a day or two of getting the vaccine. Most side effects are mild to moderate and should go away in a few days.

 

How Viral Vector Covid-19 Vaccines Work

Viral vector vaccines use a modified version of a different virus (the vector) to deliver important instructions to our cells.

1. First, the vector (not the virus that causes COVID-19, but a different, harmless virus) will enter a cell in our body and then use the cell’s machinery to produce a harmless piece of the virus that causes COVID-19. This piece is known as a spike protein and it is only found on the surface of the virus that causes COVID-19.
2. Next, the cell displays the spike protein on its surface, and our immune system recognizes it doesn’t belong there. This triggers our immune system to begin producing antibodies and activating other immune cells to fight off what it thinks is an infection.
3. At the end of the process, our bodies have learned how to protect us against future infection with the virus that causes COVID-19. The benefit is that we get this protection from a vaccine, without ever having to risk the serious consequences of getting sick with COVID-19. Any temporary discomfort experienced after getting the vaccine is a natural part of the process and an indication that the vaccine is working.
