AZD1222 appears effective, reduces positive PCR tests
Early results from three trials assessing the safety and efficacy of the Oxford University/AstraZeneca Covid-19 vaccine, AZD1222, suggest that a single dose of the vaccine is 76% effective in preventing SARS-CoV-2 infection and the shot may also reduce onward transmission of the virus, researchers reported.
Oxford University explained that the study results which were published in
The Lancet showed “a single standard dose (SD) of the vaccine reduced PCR positivity by 67%, and that, after the second dose, the SD/SD schedule reduced PCR positivity by 49.5% overall,” according to Andrew J. Pollard, MRCP, FHEA, FIDSA, FRCPCH, and colleagues from the Oxford Vaccine Group. “These data indicate that [AZD1222], used in the authorized schedules, may have a substantial impact on transmission by reducing the number of infected individuals in the population.” The study authors also reported that participants age

The Oxford University/Astrazeneca Covid-19 vaccine could cut the transmission of infections by two-thirds and a three-month delay between doses does not reduce efficacy, a new report has found.
A pre-print paper published by Oxford and the Lancet found there was a 67 per cent reduction in positive swabs among those vaccinated.
The research also found that the jab was 76 per cent effective from 22 days until 90 days after a single standard dose.
This means protection from the virus does not diminish in the three-month period between the first and second dose.

On 1 February, Gauteng’s healthcare workers will be first to receive the Covid-19 vaccine. But, as President Cyril Ramaphosa’s speech to world leaders shows, securing vaccines for the rest of the country is ongoing.
On Monday 1 February, health care workers in Gauteng will roll up their sleeves for the first dose of the Covid-19 vaccine. Frontline workers will be first in a vaccine rollout that will eventually reach 10 million people in the province, officials said.
