I agree, Meena. There really isn't anything "guaranteed to decipher misinformation". Raising the general ability to understand health topics is one of the positive approaches. Unfortunately, misinformation doesn't just arise by mistake - social and political forces are quite ready to bend the truth to suit their twisted purposes.
And, as has been noted in plenty of literature, some people find that there is an elitist element in "literacy". Going back to the pre-internet era, WM Laetsch, wrote in his chapter "A basis for better public understanding of science": "Implicit in these and similar claims is a high level of hubris. It is assumed that scientific literacy is the highest literacy and those who are deficient are less useful members of society". More recently, the discussion around the decolonialisation of knowledge has suggested that demanding literacy according to Western medical principles can involve a form of knowledge colonialism.
Incidentally, there is an excellent free course on "How to Fight Misinformation" offered by United Nations Verified and wikiknow here:
