Pfizer CEO said that a fourth dose of new crown vaccine may eventually be required

$Pfizer (PFE.US)$ According to reports, Pfizer CEO Albert Bourla said on Wednesday that due to concerns about the Omi Keron variant, a fourth dose of the new crown vaccine may eventually be needed. He used to think that the fourth stitch may need to be performed within 12 months after the third stitch, but because of Omi Keron, this timeline may need to be advanced. The company said that enhanced needles appear to provide good protection. However, some experts are skeptical about the need for multiple injections. They pointed out that if companies like Pfizer sell more vaccines, there will be higher economic benefits. Two doses have been able to effectively prevent severe illness, especially for young people.
