OC. At each step, Janssen works closely with regulatory authorities to make sure it’s meeting all requirements. The process of learning about and developing an investigational medicine is divided into four phases. “We observe people’s symptoms for seven days after each vaccination, as well as reassess them within a month. “Usually, you look at several different vaccine candidates and ultimately choose the one that has the best immune response and evidence of protection,” Dr. Douoguih says. ohnson & Johnson is known for its longstanding commitment to fighting emerging epidemics around the world.

Generally in this phase vaccines are tested in young, healthy adult volunteers. Phase 3 trials can sometimes take years. At the same time, vaccines have to go through rigorous testing and scrutiny to ensure safety, because they’re given to healthy people to prevent them from getting sick. The transition to Phase II relies on the immunogenic and toxicity results from Phase I in a small cohort of healthy volunteers. As in previous phases, adverse events can potentially occur and are not uncommon, particularly in large studies like this. This stage of preclinical work generally lasts one to two years. Click here to sign in with Vaccines 101: How Do Clinical Vaccine Trials Work? But what does this step in the process really mean? While giving the first look at actual protection, these studies are usually not large enough for us to confirm the vaccine actually does what it needs to do, and that is to protect people from the infection it's designed to provide protection from. To show this typically requires large numbers of volunteers, in the order of 10's of thousands, depending however on many factors including how widespread the infection is that the vaccine is designed to protect from. The vaccines will be produced at Janssen's facility in Leiden, the Netherlands, as well as in the U.S. and Italy.
