Marketer Anoogrehan Manoharan, who first raised the "underdose" issue when studying a video of his Covid-19 vaccination jab on May 19, said he was re-vaccinated yesterday.

This came after BP Healthcare reviewed his complaints on the matter.

The "underdosing" issue first arose when Anoogrehan reviewed a video of his AstraZeneca vaccination process and claimed that he did not receive the full dose of the vaccine.

According to product information leaflets available from the National Pharmaceutical Regulatory Agency’s website, one dose of the vaccine is 0.5ml.
