Herd immunity is not happening

Despite more than 27,000 confirmed deaths from COVID-19 in France, only 4.4% of people have actually been infected. The percentage is far below the required level — something more than 50% — to achieve herd immunity. Herd immunity would slow — but not stop — the outbreak. Results announced by Spain's health minister show a similar situation: more than 27,000 deaths and just 5% of the population tested had antibodies to the virus. “Population immunity appears insufficient to avoid a second wave” if lockdown measures are removed, say the authors of the French study. (Reuters | 2 min read)
