At the moment, there are several companies developing a vaccine for the COVID-19 virus using their formulas. None of these vaccines have reached the market yet, but the good news is that according to Pfizer / BioNTech, their vaccine appears to be 90 percent effective.
Obviously, creating a vaccine that is 100 percent effective would be a wonderful thing, but no vaccine is ever completely effective. However, the 90 percent figure appears to be a lot better than most experts had hoped for. Currently, regulators say they are ready to approve a vaccine that is 50 percent effective, so reaching a vaccine that is 90 percent effective is impressive.
According to Dr. Albert Bourla, Chairman and CEO of Pfizer, he stated:
“Today is a great day for science and humanity. The first set of results from the Phase 3 Covid-19 vaccine trial provides the first evidence of our vaccine’s ability to prevent Covid-19. We have reached this critical milestone in the vaccine development program at a time when the world is in dire need of it, as infection rates have reached new records, hospitals are close to depleting capacity, and economies are struggling to recover. ”
However, these results are based on clinical trials, so it remains to be seen whether this new vaccine will achieve the same results if it is released to the general public or not, but for the time being, Pfizer’s discovery certainly paints a future full of hope.
