Which vaccines are effective against the 501.V2 mutation?
The AstraZeneca vaccine is safe and effective, and is being used all over the world. For South Africa, however it was shown that it is less effective against the 501Y.V2 variant for people who are mildly ill. The 501Y.V2 variant is currently the dominant variant in the country.However, the AstraZeneca vaccine is still effective in protecting people against severe Covid19 symptoms, hospitalisation and death caused by the 501Y.V2
The Johnson & Johnson trial has shown that its vaccine has proved effective against the
501.V2 Variant. Early results from Moderna also suggest its vaccine is effective against this
variant. The Pfizer-BioNTech vaccine is being tested to confirm that it protects against the
new variants and early results from the trials are positive.
