The Covid-19 vaccine of Biontech enjoys a good reputation in Europe and the USA. Many people set their hopes mostly to Biontech for ending the pandemic through its´ vaccines and Biontech was specifically praised because its vaccine was thought to have significantly lower side effects.


The appearance of the virus mutations is unfortunately a real threat to worsen the situation one more time. This concern is now identified by Israeli authorities. Israel announced last week, that the effectiveness of the Biontech vaccine while facing the now dominant Delta variant has been reduced from 90% to 64%.


According to Handelsblatt.com the vaccine has only a percentage of 64% to prevent an infection but still preserves a 93% of preventing from a heavy illness. Further investigations are needed to clarify the results of the research. According to new information from multiple health agencies around the world, a third dose of the vaccine, or a second shot in the case of the Johnson & Johnson vaccine, will be needed for the new Delta variant of the virus.


To this point we can only be sure about one thing: The end of the pandemic is still not close to be finished.
