Right before this extraordinary, this cursed Crown year draws to a close, there is reason to look optimistically at the coming: soon the world may have a third vaccine against the virus. Great Britain has granted the preparation an emergency approval from AstraZeneca and the University of Oxford, and from the first week of January it will be inoculated on a large scale in addition to the Biontech / Pfizer vaccine already approved on the island. Apparently, a Moderna preparation is also about to be approved.
AstraZeneca promises that its AZD 1222 preparation will prevent a symptomatic course of Covid-19 with an average of 70 percent chance. Unlike Biontech or Moderna, who credit their vaccines each with an effectiveness of more than 95 percent, that seems very little.
Why all the fuss over a comparatively ineffective vaccine? The answer is simple: because we need it.
The pandemic situation has changed significantly in recent weeks. New mutants of the virus have emerged in the UK and South Africa that are significantly more contagious. In South Africa and the Greater London area, they have become the predominant variants within a few weeks; Everything indicates that they have a selective advantage and, if nothing is done, they will spread throughout the world. That would likely make fighting the pandemic very difficult. Significantly more stringent crown measurements would be necessary to achieve the same effects as now.
