Jay Bhattacharya Biography 2025
In 2021, Bhattacharya opposed the implementation of lockdowns and mask mandates as a response to the COVID-19 pandemic. Along with Martin Kulldorff and Sunetra Gupta, he co-authored the Great Barrington Declaration in 2020. The declaration advocated for lifting COVID-19 restrictions on lower-risk groups to achieve herd immunity through widespread infection, while also protecting vulnerable individuals from the virus. However, the declaration was met with criticism, including from World Health Organization Director-General Tedros Adhanom Ghebreyesus, who deemed it unethical and impractical.
