A little over two years ago, the first of a disease hitherto unknown in the world were detected in China. The new coronavirus has brought mourning to many families around the world since the appearance of the first cases of the disease, which affects almost every country in the world.
To counter the progression of the disease, many vaccines have been developed by laboratories. For several months now, mass vaccination campaigns have started all over the world. To date, several million people have received the two doses of the vaccine. Despite this, the disease continues to progress and new variants are discovered as time passes. In recent weeks, with the new Omicron variant hitting the world, new cases have been detected.
It must be said that the variant Omicron is more contagious than variant Delta but on the other hand it is less virulent. In several countries, there is an outbreak of cases which worries some observers. In this context, the billionaire Bill Gates spoke out during an exchange on social networks with the professor at the University of Edinburgh Davi Sridhar. The billionaire called for the manufacture of new vaccines because those available show flaws. ” The vaccines we have are very good at preventing serious illness and death, but they are missing two key things. Firstly, they still allow infections and their duration seems to be limited” , wrote Bill Gates.
The vaccines we have prevent severe disease and death very well but they are missing two key things.
First they still allow infections (“breakthrough”) and the duration appears to be limited.
We need vaccines that prevent re-infection and have many years of duration.#
