NEXT YEAR'S influenza vaccine will contain 2 new strains of the A virus.
After a review of the antigenic strains of the virus in circulation, the Vaccines and Related Biological Products Advisory Committee of the Food and Drug Administration (FDA) has recommended that the H3N2 strain in the vaccine for 1998-1999 be represented by A/Sydney/5/97, and the H1N1 strain by A/Beijing/262/95. At a meeting in January, the committee had decided to retain the present B strain, B/Harbin/7/94, in next year's vaccine (JAMA. 1998;279:783).
