Why are coronavirus vaccines – a success story in human innovation – viewed so negatively?
- The arrival of multiple highly effective and overwhelmingly safe inoculations has been accompanied by warnings and fears
- Experts say some perspective has been lost – not only did the jabs arrive in record time, they are also a way out of the pandemic

And yet, the arrival of multiple highly effective and overwhelmingly safe vaccines in record time has been accompanied by a deluge of warnings, caveats and dire prognostications that have served to emphasise the ways in which the jabs – like any medical intervention – are not absolutely perfect or free of risk.
Siddharth Sridhar, a clinical virologist at Hong Kong University (HKU), said this time last year it would have been impossible to imagine being so “spoilt for choice” with vaccines.
“The messaging needs to be simple: vaccines work at keeping people with Covid-19 alive and they do this wonderfully well,” said Sridhar, who criticised the “paralysing” and “non-stop” public discussion about variables such as whether vaccines stopped transmission, not just severe disease, or worked against the variants.
It’s a degree of negativity that is out of proportion with either the risks or limitations of vaccines, according to some experts, and threatens to undermine efforts to save lives and get societies back to normal life.
