Sweden: so much for Herd Immunity and Light Touch pandemic policies

“Instead of following evolving evidence, the [Swedish] FHM has doubled down and defended its approach without reconsidering the assumptions on which the failed national approach is based. It has downplayed the roles of asymptomatic spread, aerosol transmission, children as potential source of infection, and the use of face masks. It has maintained an approach that mainly builds on recommendations to take voluntary actions, guided (in our view) more by public opinion than by sound public health policy. “

China: Our vaccines “don’t have very high protection rates,” says the director of Chinese CCDC

China’s top disease control official says the effectiveness of Chinese vaccines is low and the government is considering mixing them to give them a boost.  Chinese vaccines “don’t have very high protection rates,” said the director of the China Centers for Disease Control, Gao Fu, at a conference Saturday in the southwestern city of Chengdu.

Beijing has distributed hundreds of millions of doses in other countries while also trying to promote doubt about the effectiveness of Western vaccines.

“It’s now under formal consideration whether we should use different vaccines from different technical lines for the immunization process,” Gao said.

The effectiveness rate of a coronavirus vaccine from Sinovac, a Chinese developer, at preventing symptomatic infections has been found to be as low as 50.4% by researchers in Brazil. By comparison, the vaccine made by Pfizer has been found to be 97% effective.

Sinovac #coronavirus vaccine – 27.7% effective within the first two weeks, 56.5% effective two weeks after the second dose

The study by the University of Chile found inoculation to be 56.5 percent effective in protecting recipients two weeks after the second dose, and 27.7 percent effective within the first two weeks.

But for a single dose, efficacy in the 28 days between the first and second dose was only three percent — on par with the margin of error in such studies, it said.

Chile goes into full #coronavirus lockdown despite world leading vaccination rates

Chile is a world leader in its coronavirus vaccination program and has already given at least one dose to almost a third of its population. By Thursday more than six million people had been given a single dose and 3.1 million both doses, including most over-70s. And yet that same day, the government put more than 80 percent of the country’s 19 million people in lockdown.

Preliminary results from a study examining the efficacy of the Oxford-AstraZeneca coronavirus vaccine indicate it is significantly effective at preventing severe illness from COVID-19.

Results of the trial, which involved more than 32,000 volunteers, showed two doses of the vaccine administered four weeks apart had an efficacy of 79% at preventing symptoms of COVID-19. In participants aged 65 years and over, vaccine efficacy could be as high as 80%, AstraZeneca announced early Monday. It had an efficacy of 100% at preventing severe disease and hospitalization.

Chile vaccinates nearly a quarter of its population against #coronavirus in a month, yet its infection rate is spiralling

Chile has begun administering second doses of Covid-19 vaccines as it presses ahead with an impressive vaccination campaign that has seen the Latin American nation become one of the fastest in the world.

Thanks to a strong public health network and a long history of effective immunisation campaigns, the government has been able to offer free jabs to almost one-quarter of its 19-million strong population in just over a month.
