We’re one step closer to getting a Covid-19 vaccine, but on the back of this positive news, what concerns should we be paying attention to?

The Pfizer and BioNTech team have announced that the vaccine they’re developing is 90% effective in protecting people from the transmission of the Covid-19 virus in global trials.

Based on the interim analysis, which will continue till December, the vaccine has performed better than expected, with no safety concerns to report so far.

Pfizer and BioNTech are looking at globally supplying up to 50 million vaccine doses in 2020, and up to 1.3 billion doses in 2021.

There’s no doubt that this is good news, but the public has been advised to be cautiously optimistic as full data is not available yet and that the trials are ongoing.
