H1N1 Genetic Changes in RBD Raise Pandemic Concerns. -- (Recombinomics)
....The above comments are from Thursday's WHO press conference and raise concerns that the sequences from Ukraine (see map ) have small changes which may include receptor binding domain changes. Several such changes have been seen in previously published sequences and position 225 has been of concern....Thus, similar changes in sequences from Ukraine would be of most interest, and such changes have not been ruled out by WHO statements thus far.
The release of these sequences from Ukraine is now overdue , and these delays increase pandemic concerns.
