Pfizer vaccine offers some defence against Omicron, new data shows
More research is necessary, but there’s a chance the body’s immune response could prove more effective at fighting it

However, researchers stressed that it does offer some protection to the ancestral variant of the coronavirus found in China in March last year.
The publication of the research came as the SA Health Products Regulatory Authority (SAHPRA) announced on Wednesday the go-ahead for a Pfizer Covid-19 booster shots for people over 18.
It approved an “optional third (booster) dose” to be administered at least six months after the second dose. ..
