Coronavirus digest: J&J says second shot boosts protection

A booster dose of the Johnson & Johnson COVID jab increases its efficacy rate to 94%, the drugmaker said. The company is expected to state its case to US regulators. Follow DW for the latest.

J&J is expected to use data to bolster the case for booster shots

In the United States, pharmaceutical company Johnson & Johnson said a second shot of its COVID-19 vaccine given two months after the first dose increased efficacy to 94%. This was found to be the case against moderate to severe courses.

A single dose has been found to give 70% protection.

"A booster dose of the Johnson & Johnson COVID-19 vaccine further increases antibody responses among study participants who had previously received our vaccine,'' said Dr. Mathai Mammen, head of research and development at J&J.

US President Joe Biden has been pushing for widespread booster shots, but his vaccination campaign received a blow last week, when a panel of experts advising the US Food and Drug Administration, recommended against booster shots for younger population groups.

Australian authorities used pepper spray, rubber ball grenades and foam baton rounds to disperse violent protests against mandatory vaccinations in Australia’s second-largest city, Melbourne, on Tuesday. 

The demonstrators moved through the city center, throwing bottles, lighting flares and attacking police cars as they chanted slogans against COVID-19 vaccines and lockdown measures.

Melbourne has been under lockdown for seven weeks as the city struggles to control the spread of the highly infectious delta variant.
