S. African govt halts AstraZeneca vaccine

Johannesburg: South Africa will suspend use of AstraZeneca’s Covid-19 shot in its vaccination programme after data showed it gave minimal protection against mild to moderate infection caused by the country’s dominant coronavirus variant.

Johannesburg, Feb. 8: South Africa is considering giving a Covid-19 vaccine that is still in the testing phase to health workers, after suspending the rollout of another shot that preliminary data indicated may be only minimally effective against the mutated form of the virus dominating the country.

The country was scrambling Monday to come up with a new vaccination strategy after it halted use of the AstraZeneca vaccine _ which is cheaper and easier to handle than some others and which many had hoped would be crucial to combatting the pandemic in developing countries.

Among the possibilities being considered: mixing the AstraZeneca vaccine with another one or giving Johnson & Johnson's single-dose vaccine, which has not yet been authorised for use anywhere, to 100,000 health care workers while monitoring its efficacy against the variant.

The abrupt change in strategy was prompted by preliminary results in a small study that showed the AstraZeneca vaccine was only minimally effective against mild to moderate cases of the disease caused by the variant.

There is reason to hope the Johnson & Johnson vaccine may fare better in the country.
