The Johnson & Johnson (Janssen) COVID-19 vaccine is a single-shot viral vector vaccine that uses a modified, harmless virus (not related to the virus that causes COVID-19) to enable cells in the body to produce a protein from the COVID-19 virus. This means that the J&J vaccine does not contain the live coronavirus that causes COVID-19.

The J&J vaccine does not contain the live coronavirus that causes COVID-19
The Johnson & Johnson (J&J) COVID-19 vaccine is a viral vector vaccine. It uses a modified, harmless virus (unrelated to the virus that causes COVID-19) to enable cells in the body to produce a protein from the COVID-19 virus. This protein is harmless and cannot cause COVID-19, but it stimulates the immune system to fight future infections.
Dr. Sharon Welbel, the director of Hospital Epidemiology and Infection Control for Cook County Health, also confirmed that the J&J vaccine is not a live vaccine. She explained that it contains only a small piece of the virus's genetic code, which instructs our bodies to create a specific protein that triggers an immune response.
The J&J vaccine is a single-shot vaccine, unlike the two-dose mRNA vaccines such as Pfizer and Moderna. While the J&J vaccine has been paused in the past, it was considered up-to-date as of May 6, 2023, for those who followed the recommendations for getting one of the currently available updated vaccines.

The J&J vaccine uses a modified, harmless adenovirus to enable cells to produce a protein
The Johnson & Johnson COVID-19 vaccine is a viral vector vaccine. Viral vector vaccines use a modified, harmless adenovirus to enable cells in the body to produce a protein from the COVID-19 virus. The adenovirus used in the J&J vaccine is not related to the virus that causes COVID-19 and cannot cause COVID-19. Instead, it stimulates the immune system to fight future infections.
The J&J vaccine uses the adenovirus as a vector to carry the spike gene into the body. Once inside the body, cells make harmless copies of the spike protein to prime the immune system. The immune system then reacts to the spike protein and creates antibodies to fight the virus that causes COVID-19.
The J&J vaccine is different from traditional vaccines, which introduce a weakened or inactivated germ into the body. The J&J vaccine does not contain any live virus and cannot give someone COVID-19. It is also different from mRNA vaccines, such as the Pfizer and Moderna vaccines, which contain material from the virus that causes COVID-19. mRNA vaccines give cells instructions for how to make a harmless protein that is unique to the virus.
The J&J vaccine was paused in 2021 due to safety concerns, but it has since been updated and is now available as an updated vaccine. The original J&J vaccine expired as of May 6, 2023, and is no longer available in the US. However, those who received the original J&J shot are considered up-to-date if they follow the recommendations for getting one of the currently available updated vaccines.

The J&J vaccine cannot give someone COVID-19
The Johnson & Johnson (J&J) COVID-19 vaccine is a single-shot vaccine that uses an adenovirus. Importantly, it does not contain the live coronavirus that causes COVID-19. The J&J vaccine uses a modified, harmless virus (not related to the virus that causes COVID-19) to enable the body's cells to produce a protein from the COVID-19 virus.
This protein is harmless and cannot cause COVID-19, but it stimulates the immune system to fight future infections. The J&J vaccine is similar to mRNA vaccines in this way. mRNA vaccines contain the material from the virus that causes COVID-19, which gives our cells instructions for how to make a harmless protein that is unique to the virus.
These vaccines do not contain any live virus, and they cannot give someone COVID-19. Our cells make copies of the protein and destroy the genetic material from the vaccine. Our immune systems react to the protein and create antibodies to fight the virus that causes COVID-19 if we are infected in the future.
To transmit COVID-19, you would have to have the live coronavirus in your body. None of the available vaccines, including the J&J vaccine, contain the live virus in any amount. The J&J vaccine cannot give someone COVID-19, nor can it make them sick with COVID-19.

The J&J vaccine does not make you shed spike proteins
The Johnson & Johnson (J&J) vaccine does not make you shed spike proteins. Firstly, it's important to understand how vaccines work. Vaccines generally introduce a piece of a virus or bacteria into your body so that you can develop long-lasting immunity to the pathogen. This piece introduced by the vaccine rapidly fades away, but your body's immune system remembers it. When it encounters the virus or bacteria again, it can mount a strong immune response, preventing or reducing the severity of infection.
The J&J vaccine is a viral vector vaccine, which is different from an mRNA vaccine. It uses a harmless adenovirus to deliver genetic instructions to your cells, teaching them to create a protein unique to the SARS-CoV-2 virus, known as the spike protein. This spike protein is critical for the virus's entry into human cells. However, the spike protein generated by the vaccine is quickly identified, attacked, and destroyed by your immune system because it recognises it as foreign.
There is no evidence that the spike protein or any other part of the J&J vaccine accumulates in any organ or is shed from the body. The vaccine's spike protein may be detected in the lymph nodes, but this is normal, as lymph nodes act as the body's waste removal system. The presence of spike protein in the lymph nodes indicates that the vaccine is working as intended, triggering the production of antibodies.
While some people have expressed concerns about the potential impact of spike proteins, it's important to understand that the experiments suggesting potential issues were conducted in cells specifically engineered to produce spike proteins constantly. This is not representative of how spike proteins behave in the body after vaccination, where the mRNA that instructs cells to create spike proteins breaks down within a few days.
In summary, the J&J vaccine does not make you shed spike proteins. The spike proteins generated by the vaccine are short-lived and do not accumulate or cause harm to the body. The vaccine effectively triggers your immune system to create antibodies, providing protection against SARS-CoV-2 without any risk of shedding spike proteins.

The J&J vaccine cannot make you sick with COVID-19
The Johnson & Johnson (J&J) COVID-19 vaccine is a viral vector vaccine. It uses a modified, harmless virus (not related to the virus that causes COVID-19) to enable cells in the body to produce a protein from the COVID-19 virus. This protein is harmless and cannot cause COVID-19, but it stimulates the immune system to fight future infections.
The J&J vaccine does not contain the live coronavirus that causes COVID-19. According to the CDC, none of the COVID-19 vaccines contain the live virus in any amount. As Dr. Kiran Joshi, Senior Medical Officer and Co-Lead at the Cook County Department of Public Health, states:
> "None of the COVID-19 vaccines can make you sick with COVID-19, nor do they contain the live virus in any amount. COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19."
Dr. Sharon Welbel, the director of Hospital Epidemiology and Infection Control for Cook County Health, also confirms that the J&J vaccine is not a live vaccine. She explains that it contains only a "snippet" of the virus's genetic code, which instructs our bodies to create a specific protein that triggers an immune response.
The J&J vaccine is safe and effective at preventing severe disease, hospitalization, and death from COVID-19. While the J&J vaccine has since expired as of May 6, 2023, and is no longer available in the US, those who received the shot are considered up-to-date if they follow the recommendations for getting one of the currently available updated vaccines.
