Johnson & Johnson said on Wednesday Canada gave full approval to its single-shot COVID-19 vaccine for people aged 18 years and older.
The J&J COVID-19 vaccine leverages the AdVac vaccine platform, a unique and proprietary technology that was also used to develop and manufacture Janssen’s European Commission-approved Ebola vaccine regimen and construct its investigational Zika, RSV, and HIV vaccines.

Last month, a study run by the US National Institutes of Health showed that people who got Johnson & Johnson’s COVID-19 vaccine as a first shot had a stronger immune response when boosted with vaccines from Pfizer/BioNTech or Moderna.
The study, which included more than 450 adults who received initial shots from Pfizer, Moderna, or Johnson & Johnson, showed that “mixing and matching” booster shots of different types is safe in adults. Moderna’s and Pfizer’s vaccines are based on messenger RNA while J&J’s uses viral vector technology.

Janssen COVID-19 Vaccine Ingredients
All COVID-19 vaccine ingredients are safe. Nearly all of the ingredients in COVID-19 vaccines are also the ingredients in many foods – fats, sugars, and salts. The J&J/Janssen COVID-19 vaccine also contains a piece of a modified virus that is not the virus that causes COVID-19. This modified virus is called the vector virus. The vector virus cannot reproduce itself, so it is harmless. This vector virus gives instructions to cells in the body to create an immune response. This response helps protect you from getting sick with COVID-19 in the future. After the body produces an immune response, it discards all of the vaccine ingredients just as it would discard any information that cells no longer need. This process is a part of normal body functioning.
