THE University of Dundee is seeking thousands of volunteers for a new study assessing the effectiveness and safety of Covid-19 vaccines. Researchers are hoping that the VAC4COVID study will help scientists and doctors understand people’s health experiences after vaccination and support public confidence. Launched by the university’s Medicines Monitoring Unit (MEMO Research) thousands of volunteers are required to take part so researchers can detect if there are any unexpected, rare conditions linked to vaccination. All vaccines must meet rigorous quality, safety and efficacy standards before being approved. But, as with any new medicines or treatments, ongoing research is needed to fill any gaps in the knowledge obtained from clinical trials.
