“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’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.
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’s big coronavirus vaccine bet on China’s Sinovac shots. Chile hopes to reach herd immunity by the middle of the year and is nearly halfway to vaccinating its entire population. The Chinese made Sinovac vaccine has played a major part in the campaign, despite not releasing final phase data.
“This Monday the most restrictive measures to stop contagions begin to take effect: curfew at 9 p.m. and border closures
On this day, the borders will be closed for at least 30 days, and the curfew will begin at 9:00 p.m., extending until 5 a.m. There will also be new limitations to essential activities, where by essential good will be understood those essential goods for subsistence, telework, real estate security, distance education.“
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 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.
