Covishield Dosage Interval: Based on Science or Vaccine Shortage?

·1-min read

Just seven weeks after it directed state governments to increase the gap between two doses of Covishield vaccines to 6-8 weeks, on 13 May, the Union Health Ministry once again announced a further extension of the gap to 12-16 weeks, citing “real-world evidence” in the United Kingdom on vaccine efficacy.

This recommendation was made by the National Expert Group on Vaccine Administration for Covishield only.

However, the decision comes at a time when the country is facing a severe shortage of vaccines – specifically Covishield, which has been used to inoculate the majority of the population so far.

The change in vaccine dosage policy has raised a lot of curiosity, with many many wondering if the decision is based on scientific data or is it meant to cover up the vaccine shortage in the country.
