Policymakers are devising plans to compress the years it usually takes to develop a vaccine.
Hundreds of people are rolling up their sleeves in countries across the world to be injected with experimental vaccines that might stop COVID-19, spurring hope —maybe unrealistic — that an end to the pandemic may arrive sooner than anticipated.
About 100 research groups are pursuing vaccines with nearly a dozen in early stages of human trials or poised to start. It’s a crowded field, but researchers say that only increases the odds that a few might overcome the many obstacles that remain.
"We’re not really in a competition against each other. We’re in a race against a pandemic virus, and we really need as many players in that race as possible,” Dr. Andrew Pollard, who is leading the University of Oxford’s vaccine study, told The Associated Press.
The hard truth: There’s no way to predict which — if any — vaccine will work safely, or even to name a front-runner.
As Dr Anthony Fauci, the US government’s top expert, put it: "You need more shots on goal for a chance at getting a safe and effective vaccine.”
The first cautious tests of March, when small numbers of volunteers got injections to check for side effects, have turned into larger studies in China, the US and Europe to look for hints that different vaccine candidates really protect.
Next: Finding out for sure if any of the vaccines work in the real world by testing large groups of people in areas where the virus is circulating - a tricky prospect when study participants may be in places where the virus is fading or they are told to stay home — and finding a way to quickly distribute lots of doses of any successful candidates.Reuters
It’s best to avoid certain painkillers before and after getting a COVID-19 vaccine, unless you routinely take them for a medical condition.
The US Centers for Disease Control and Prevention (CDC) said on Wednesday the vaccines have been shown to prevent symptomatic COVID-19, thought to play a greater role in the transmission of the virus than asymptomatic disease.
The ministry urged the pilgrim to obtain an approved and negative laboratory examination for the coronavirus 72 hours before the arrival in the Kingdom.
There were no immediate reports of casualties from the strikes and no claim of responsibility, two police officers said. A number of Shi'ite Muslim militant groups have offices and supporters in eastern Baghdad.
Both had pleaded not guilty to charges of violating the official secrets act, which carries a maximum sentence of 14 years. "Three years each, no hard labour," said the source, who declined to be identified due to the sensitivity of the issue.
Chanting the same "Women, life, freedom!" mantra used in demonstrations in Iran, about 25 Afghan women protested in front of the Iranian embassy in Kabul, before being dispersed by Taliban forces firing in the air, an AFP correspondent reported.
