There’s further good news on a vaccine for Covid 19.
Pfizer has finished its Phase 3 study and says its vaccine is 95% effective with no major side effects.
The pharmaceutical giant, along with its partner BioNTech, previously said its vaccine was 90% effective at the earlier stage of its Phase 3 study.
It now says that this has moved to 95% as it’s completed this phase. The vaccine is 94% effective in people over the age of 65.
Pfizer also says trials on 43,000 volunteers found no serious safety concerns. A few had headaches and fatigue, but that’s not unusual for a vaccine
It will now apply for US authorisation within days and will submit its data to regulatory agencies around the world.
This welcomed development comes on top of news from another firm Moderna which said its vaccine was also almost 95% effective based on preliminary data.
