The statement said that some discussions about changing the dose of the new vaccine suggested that changing the dose would help to provide more vaccines to the public more quickly. "However, without sufficient scientific evidence to support such a change, it may eventually have adverse effects on public health" and "there is a great risk of putting public health at risk".

The statement also said that the existing data support the continued vaccination of specified doses at specified intervals, with Pfizer's interval of 21 days and Modena's interval of 28 days. Two different mRNA vaccines now show about 95% effectiveness in preventing adult infection with NCV.

According to the world wide web, on January 3 local time, Reuters quoted us federal government officials as saying that the US government is considering injecting half dose of Modena vaccine to some people to achieve rapid vaccination. According to Reuters, the source of the news was munseff slavey, chief consultant of the US vaccine and drug research program "warp speed".

"We know that for the Modena vaccine, giving half the dose to people between the ages of 18 and 55, twice, is half the dose, which just means the goal of doubling the number of people vaccinated with the existing vaccine stock," slavi said "We know that [half the dose] can produce exactly the same immune response as a full dose," he added.
