The COVID-19 vaccine which currently under development by Pfizer and BioNTech has been found to be 90% effective in its prevention of the virus.
In the third phase of clinical trials, Pfizer brought in 43,538 participants and utilised two different doses, one being immunisation and the other being a placebo.
It resulted that 90% of participants were safe from the virus after 28 days of receiving the immunisation.
This scientific breakthrough has been called “a great day for science and humanity” by Pfizer Charmain Dr. Albert Bourla.
