Virus expert pushes for mixing jabsRespected virus expert Yong Poovorawan insisted mixing and matching vaccines is a safe and effective method for fighting the fast-spreading Delta variant of Covid-19, even after a World Health Organization (WHO) scientist on Monday advised against it. His remark came after WHO chief scientist Soumya Swaminathan advised against people mixing and matching Covid-19 vaccines from different manufacturers, calling it a "dangerous trend" since there is little data available about the health impacts. Data from mix and match studies of different vaccines are awaited -- immunogenicity and safety both need to be evaluated." That led to studies of injecting the inactivated virus of the Sinovac vaccine in the first dose to be followed soon by the second dose of AstraZeneca. The studies were put into practice and it was found that the cross-vaccination was able to spur body immunity higher and faster than anticipated, Prof Yong explained.
