‘Much-required’ extra vaccination alternative
“The U.S. regulatory authorities are reluctant, even in a pandemic, to rely totally on data obtained outside the U.S., so this trial was done to provide convincing evidence of efficacy and safety in a sufficiently large number of U.S. patients,” stated Stephen Evans, teacher of pharmacoepidemiology at the London School of Hygiene & Tropical Medicine.
“This is good news for the global community, and one hopes that any political statements around this good news are avoided,” Evans stated.
Among the individuals in the interim analysis, approximately 20% were 65 or older, while roughly 60% had actually comorbidities connected with an increased threat for development of serious Covid, such as diabetes or heart illness.
