  • According to the study published in The Lancet Journal, the protection offered by the Oxford-AstraZeneca (known as Covishield in India) COVID-19 vaccine declines after three months of receiving two doses of the preventive.
  • The findings drawn from datasets in Brazil (for 42 million people) and Scotland (for 2 million people) suggest that booster programmes are needed to help maintain protection from severe disease in those vaccinated with AstraZeneca.

The Lancet is a weekly peer-reviewed general medical journal. It was founded in 1823 by Thomas Wakley, an English surgeon who named it after the surgical instrument called a lancet.
