French President Emmanuel Macron on Monday took to Tik Tok and Instagram to try to counter misinformation about vaccines following a third weekend of demonstrations over a controversial Covid-19 health pass, according to AFP.

Macron discarded his customary dark suit and tie for a black t-shirt in a short video from the presidency's holiday residence in southern France, in which he repeated that vaccines were the “only weapon” that could beat back a fourth wave of coronavirus.

“Some of you have been hearing false rumours, some of it rubbish it has to be said,” he said in the selfie video, in which he urged the vaccine-shy to put their questions and concerns directly to him.

He was speaking after an estimated 200,000 people demonstrated across France on Saturday.

The protests were the biggest since Macron last month announced that people would have to furnish proof of vaccination, a negative Covid-19 test or recent recovery from Covid-19 to gain entry to most museums, cinemas and sports venues.
