ItвЂ™s been a week that is busy so for news about COVID vaccines. First we heard preliminary trial that is clinical from the Pfizer vaccine, then the Russian Sputnik V vaccine. This week, we learned about the Moderna vaccine. All these results had been shared with the media, ahead of being peer reviewed and published in a journal.
Once we anticipate preliminary outcomes from more vaccine studies become released into the coming days and months, itвЂ™s essential to understand whatвЂ™s behind these announcements, just what news reports donвЂ™t tell us, and exactly what scientists donвЂ™t yet understand.
This can help us identify news that is g d we see it, become more critical of news reports, or delay our judgement until we now have more information.
1. Does the news report tell me exactly what style of trial it really is?
At this time for the pandemic, trial outcomes making the news are often the interim results of late-stage trials that are clinical known as period 3. This really is when a vaccine is given to thousands of people and tested for just how well it works and whether it is safe (more on these dilemmas later).
The vaccine arm (people who get the actual vaccine), and the placebo arm (people who get the placebo, usually an inert substance, such as a saline injection) in these trials, volunteers are randomised into two study arms.
