According to the director of clinical development at vaccine developer Moderna, Tal Zaks, the public should not “overinterpret” the results of the vaccine study. People should not think that life will return to normal once a certain number of adults get vaccinated.
According to Zaks, Moderna’s study results show that the vaccine can prevent someone from getting sick or “seriously ill” with Covid-19. However, it is not clear from the data so far whether the vaccine also prevents the transmission of the virus.
“So far it is not clear whether the vaccine prevents you from possibly carrying the virus temporarily in you and infecting others,” Zaks said in an interview with “Axios”. He added: “When we begin using the vaccine, we will not have enough concrete data to demonstrate that the vaccine is curbing transmission.”
Vaccine alone is not a reason for behavior change
Based on the scientific evidence, he assumes that the vaccine is likely to prevent transmission, but there is no solid evidence yet. “I think it’s extremely important that we don’t change our behavior based on a vaccine alone,” he said.
Moderna’s Covid-19 vaccine is one of three vaccines that have shown effectiveness in clinical trials. According to the company, this vaccine protects people 94.5 percent against Covid-19.
Moncef Slaoui is the head of Operation Warp Speed, which is responsible for the development and distribution of the vaccine in the White House. He announced on Sunday that the company would apply for emergency approval from the U.S. regulatory agency for its Covid-19 vaccine by the end of November.
Pfizer and Biontech applied for FDA emergency approval for their equally highly effective vaccine last Friday. On Monday, Astrazeneca and the University of Oxford also reported that their vaccine against Covid-19 is effective.
