Herd immunity

Government scientists talked up the prospect of the country building up a "herd immunity" to Covid-19 despite private warnings that patients could become re-infected as little as three months after their first illness, The Telegraph can disclose.

Members of one of the most influential panels guiding the government's response to the virus warned that the length of immunity was "unclear" and that just 12 weeks "may be a reasonable point" after which those who suffered a mild illness could become susceptible to a second infection.

The private warnings were issued on March 13, the same day that Sir Patrick Vallance, the chief scientific adviser, sparked major controversy when he said the Government's aim was to "build up some kind of herd immunity so more people are immune to this disease"....
