Scientists use lab tests and testing in animals, such as mice or monkeys, to learn whether a vaccine might work. This stage usually lasts 1 to 2 years. Many potential vaccines don't make it past this point. But if the tests are successful and the FDA signs off, it's on to clinical testing.
Whatever the case, what happens on Phase 1 of vaccine trial?
Before a vaccine is available to the public, it must go through several stages of testing. The first stage is a Phase 1 clinical trial. In Phase 1, the vaccine is given to healthy volunteers to test if it’s safe and induces an immune response against the virus.
No matter, what is the first stage of COVID-19 vaccine development?
The first stage is a Phase 1 clinical trial. In Phase 1, the vaccine is given to healthy volunteers to test if it's safe and induces an immune response against the virus. Scientists began Phase 1 trials of an experimental vaccine for COVID-19 in mid-March.
Other than that, what happens during the second development phase for a COVID-19 vaccine?
Clinical development is a three-phase process. During Phase I, small groups of people receive the trial vaccine. In Phase II, the clinical study is expanded and vaccine is given to people who have characteristics (such as age and physical health) similar to those for whom the new vaccine is intended.
How does the Pfizer-BioNTech COVID-19 vaccine work?
The Pfizer-BioNTech COVID-19 vaccine (COMIRNATY) also contains a harmless piece of messenger RNA (mRNA). The COVID-19 mRNA teaches cells in the body how to create an immune response to the virus that causes COVID-19. This response helps protect you from getting sick with COVID-19 in the future.
