In a positive turn of events amidst the escalating COVID-19 crisis in the U.S., pharmaceutical company Moderna has revealed promising preliminary results from its extensive clinical trial for a COVID-19 vaccine, indicating an impressive 94.5 percent effectiveness. This announcement comes closely on the heels of Pfizer’s report of a 90 percent efficacy for its own vaccine.
While both vaccines face various challenges before they can be broadly administered, experts hold cautious optimism that they may pave the way toward controlling the pandemic in 2021. Moderna’s CEO, Alex Turner, expressed that this data represents a significant validation of their vaccine’s ability to prevent COVID-19, particularly severe cases. Meanwhile, Moderna’s President, Jamie Fields, stated, “We’re on track to deliver a vaccine that can effectively combat COVID-19.”
Although Moderna is still gathering necessary safety data for an emergency use authorization (EUA) from the FDA, they anticipate completing that process shortly. Reports suggest that the company could submit for EUA by the end of the month. Should both Moderna and Pfizer receive approval, the U.S. might have access to two vaccines by year’s end, with both companies capable of producing a combined 60 million doses by January.
The findings, shared through press releases, have not undergone peer review yet, so definitive conclusions can’t be drawn. However, Dr. Samuel Harris, a leading infectious diseases expert, expressed enthusiasm about the developments. “I had anticipated a 75 percent efficacy, and seeing 94.5 percent is truly remarkable,” he noted.
Moreover, the success of these two vaccines reinforces the viability of this new messenger RNA technology, offering a promising avenue for future vaccine developments against both COVID-19 and other infectious diseases, according to Dr. Lisa Fernandez, a public health researcher at Stanford University.
Nonetheless, while this news is encouraging, the pandemic is far from over. Vaccines won’t be widely accessible until at least spring, and it’s crucial to continue practicing safety measures such as mask-wearing and social distancing to mitigate the spread and protect lives.
