UPDATE 1-Booster shots may be needed within a year after COVID-19 vaccinations -U.S. official

on COVID-19 vaccine boosters)
    April 15 (Reuters) - The United States is preparing for the
possibility that a booster shot will be needed between nine to
12 months after people are initially vaccinated against
COVID-19, a White House official said on Thursday. 
    While the duration of immunity after vaccination is being
studied, booster vaccines could be needed, David Kessler, chief
science officer for President Joe Biden's COVID-19 response task
force told a congressional committee meeting. 
    "The current thinking is those who are more vulnerable will
have to go first," Kessler said.
    Initial data has shown that vaccines from Moderna Inc
 MRNA.O  and partners Pfizer Inc  PFE.N  and BioNTech SE
 BNTX.O  retain most of their effectiveness for at least six
months.  urn:newsml:reuters.com:*:nL1N2M62JG
    Even if that protection lasts far longer, experts have said
that rapidly spreading variants of the coronavirus and others
that may emerge could lead to the need for regular booster shots
- such as with annual flu shots. 
    The United States is also tracking infections in people who
have been fully vaccinated, Rochelle Walensky, director of the
U.S. Centers of Disease Control and Prevention told the House
subcommittee hearing. 
    Of 77 million people vaccinated in the United States, there
have been 5,800 such breakthrough infections, Walensky said,
including 396 people who required hospitalization and 74 who
died. 
    Walensky said some of these infections have occurred because
the vaccinated person did not mount a strong immune response.
But the concern is that in some cases, they are occurring in
people infected by more contagious virus variants.
