U.S. public health advisers are weighing recommendations for extending the interval between the first and second doses of Covid-19 vaccines, a potential strategy for quickly getting protection to more people amid the spread of new variants.
A working group of the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices has debated the idea, according to a person familiar with the discussions. It hasn’t been decided if the full committee will take up the issue and provide official guidance, the person said. Jose Romero, chairman of the committee and Arkansas health secretary, declined to comment because the deliberations are confidential.
