The concept of ending the Covid pandemic through herd immunity is “a dangerous fallacy unsupported by scientific evidence”, say 80 researchers in a warning letter published by a leading medical journal…
There is no evidence that immunity after recovering from Covid-19 lasts, they say, adding that people who are vulnerable would be at risk for the indefinite future and cannot be kept safe.
“Prolonged isolation of large swathes of the population is practically impossible and highly unethical,” they say, calling for action to suppress the levels of virus in the population.
“It is critical to act decisively and urgently,” they say. “Effective measures that suppress and control transmission need to be implemented widely, and they must be supported by financial and social programmes that encourage community responses and address the inequities that have been amplified by the pandemic.”
