Pfizer booster shots are now being considered for South Africa, but their safety and effectiveness have yet to be tested.
The South African Health Products Regulatory Authority (Sahpra) says it has received an application for the Pfizer booster injection on 17 November 2021.
An assessment of data on the safety and efficacy of the third dose will now begin.
“Pfizer’s latest request says the results of a Phase 3 clinical trial with more than 10,000 participants found that the third dose was safe and effective,” Sahpra said.
This comes after the US Food and Drug Administration (FDA) on Friday supported the emergency authorizations for reinforcement shots of the Pfizer and Moderna Covid-19 vaccines.
This means that all adults in the US are now eligible for an additional injection six months after the second dose and can be given at any time thereafter.
According to the World Health Organization (WHO), booster doses are administered to those who have completed a primary vaccination series.
Last month, Sahpra and Johnson & Johnson (J&J) approved vaccine booster doses for all healthcare workers who received the first injection as part of the Sisonke study.
That was after the FDA recommended a second dose of the J&J vaccine for all Americans 18 years and older who received a single dose.
According to the Department of Health’s latest data, 81,840 J&J booster doses have been administered to healthcare workers since deployment began this month.
