THE Therapeutic Goods Administration (TGA) has shot down reports that mRNA-based COVID-19 vaccinations are contaminated with excessive levels of DNA.
The government body said it constantly reviews the latest scientific information about vaccine safety and that the claim failed to apply the required scientific rigour in pharmaceutical testing, leaving the results unreliable and creating concern regarding the safety of the vaccine.
MEANWHILE, a study to improve the safety and efficiency of mRNA vaccines has been carried out by RMIT and the Doherty Institute.
Using 156 blood samples from 19 people over 28 days after receiving a Moderna Spikevax mRNA booster, the study showed how mRNA and its nanoparticle shell peaked in the bloodstream two days after the jab, and in some cases remained for a month.
RMIT University School of Science Fellow, Dr David Ju, said the study was aimed at understanding the behaviour of anti-PEG antibodies and developing safer vaccines with fewer side effects such as headache, fever and fatigue.
"Understanding the causal relationship between the amount of vaccine circulating in the blood and these side effects will be an important area for future research," Ju said.
"To be clear, the amounts of the vaccine entering the bloodstream are very small, so people can be confident that mRNA vaccines are safe and effective," he added.
