Rumours and misinformation spread about Covid vaccines should be ignored as these vaccines are "completely safe and effective", Union Health Minister Harsh Vardhan Singh said today as he unveiled posters to address the issue of vaccine hesitancy in some sections of the population. "The vaccines - Covaxin (produced by Serum Institute of India) and Covishield (by Bharat Biotech) are safe to use. The so-called side-effects are normal to any vaccination process. The paradox is that countries across the globe are asking us for access to the vaccines, while a section of our own is fomenting misinformation and doubt for narrow political ends," Mr Vardhan said.
