News Description

BHEKISISA As of 9 September, 180 COVID-19 vaccine candidates are being tested around the world, according to the World Health Organisation — but only 35 of those have managed to make it out of the lab into human trials. And of the candidates being tested on people, only about a quarter — 9 — have made it to phase three trials, which is the stage during which the vaccine is being tested on a large number of people for efficacy and safety. Trials traditionally go through several stages, beginning with laboratory tests and animal studies, to ensure that they are safe and demonstrate some benefit. If positive results are obtained during this stage, by means of an immune response against the virus, the research can then progress to human trials, which occur in three phases. Each stage gets progressively bigger in size and fine-tunes details such as the correct dosage required, with phase three being the final stage before seeking regulatory approval if the vaccine turns out to be effective.
