WHO picks new B strain for 2009-10 flu vaccine

first_imgFeb 13, 2009 (CIDRAP News) – Because of a suboptimal match between this year’s flu vaccine and circulating influenza B viruses, the World Health Organization (WHO) has recommended changing one of the three strains used in flu vaccines for the Northern Hemisphere next fall and winter.The WHO’s choices for the two influenza A strains remain the same as last year, according to new reports published on the WHO Web site this week. The agency recommended keeping the influenza A/H1N1 and A/H3N2 variants used in this year’s vaccine, both of which are labeled Brisbane strains.The influenza B component of this year’s flu vaccine was from the Yamagata lineage, but the proportion of strains from the Victoria lineage continues to increase and has become predominant in many countries, the WHO said. The US Centers for Disease Control and Prevention’s (CDC’s) most recent flu surveillance report, for the week of Feb 1 through 7, said that of 78 influenza B viruses that were characterized, 55 belonged to the Victoria lineage.Health officials in the United States have discussed including both lineages in the seasonal vaccine to address the unpredictable prevalence of the influenza B strains, especially since a vaccine against one lineage offers little protection against the other.Last year the WHO recommended a total vaccine makeover for the 2008-09 flu season because of a mismatch to circulating strains the previous season.Each February the WHO assesses the flu virus strains in circulation before picking the strains for the next Northern Hemisphere flu season. It takes about 6 months for vaccine manufacturers to grow the viruses in chicken eggs and formulate them into trivalent (three-strain) vaccines. Changing one or two strains is not unusual.The WHO recommends the following for next season’s vaccine:For the H1N1 component, a strain similar to A/Brisbane/59/2007For the H3N2 component, a strain similar to A/Brisbane/10/2007For the B component, a strain similar to B/Brisbane/60/2008-like virus, replacing B/Florida/4/2006The Brisbane strains of H1N1 and H3N2 will be used in this year’s vaccine for the Southern Hemisphere, where the flu season runs from May through October, according to the WHO. However, the influenza B component of the Southern Hemisphere’s vaccine is similar to B/Florida/4/2006.In its full report on the strain selection, the WHO said that between September 2008 and January 2009, Africa, the Americas, Asia, Europe, and Oceania all reported influenza activity. Though levels were lower than in the same period last year, activity was higher in some European countries, including the United Kingdom, Norway, Portugal, Spain, Poland, and the Netherlands.In the Northern Hemisphere, countries such as Japan, Tunisia, and European countries reported regional outbreaks of H3N2 in December and January. In the United States, H1N1 viruses predominated, while in Canada, B viruses were more common.H1N1 strains that show resistance to the antiviral drug oseltamivir (Tamiflu), one of two neuraminidase inhibitors recommended for treatment, predominated in most regions of the world. No such resistance was seen in H3N2 or B viruses, and there were no reports of viruses resistant to zanamivir (Relenza).See also:CDC flu surveillance reportJan 16 CIDRAP News story “Experts consider 4-strain flu vaccine to fight B viruses”last_img read more

Amazing Džumhur defeated Kukushkin and qualified for the 4th Round in Miami!

first_imgDamir Džumhur continued the series of successes at the Masters in Miami.In the third round, the best BiH tennis player defeated Mikhail Kukushkin with 2:1 in sets after nearly two hours of game. Already in the third game of the first set, the Kazakhstani tennis player made a break. However, Džumhur tied in the sixth game (3:3). In the next service-game, Džumhur lost his service again. Kukushkin took advantage of it and won the first set with 6:4 after 46 minutes.In the second set, the roles reversed. Damir played on a high level, while Kukushkin made one mistake after another. Damir won the first five games and it was clear that the second set will go to him. After only 30 minutes of play, Džumhur won the second set with 6:1.At the beginning of the third set, Damir made a break. However, Kukushkin responded immediately and tied to 1:1. The deciding break in the third set occurred in the fifth game, when Kukushkin played his service very poorly and Damir came to, as it will turn out, the key advantage in the match. Until the end, Džumhur kept his services, made another break and came one step away from the victory (5:2). Then Kukushkin, just like Nadal in the last round, asked for medical help. Nevertheless, after medical intervention he continued playing. Džumhur was confident in his service and in the end celebrated with 6:2 after 43 minutes of play.The result of mutual duels of these two tennis players is now 1-1. In the fourth round, Džumhur will play against the winner of the duel Miloš Raonić – Jack Sock.(Source: klix.ba)last_img read more

‘Return of the Dragon’

first_imgGIRLS CITY LEAGUE CHAMPS—The Allderdice girls team celebrates their City League Championship as Dr. Linda Lane, superintendent of Pittsburgh Public Schools, presents them with the championship trophy, Feb. 25. Allderdice (21-3) beat Westinghouse (19-5) 49-46. See story and more photos on C5. (Photo by William McBride) by Malik Vincent New Pittsburgh Courier Recalling reigning All-City MVP Justin Dobbs’ sophomore year, another player who led his team in scoring all season long did so again in the City Championship game. Behind sophomore JaVaughn Moultrie’s 15 points, the Courier’s preseason favorite Allderdice (18-6) edged USO (University Prep, Sci-Tech, and Obama), 56-49, for their third consecutive City title on Feb. 25 at Peabody.Jevaughn’s twin, DeVaughn, also chipped in seven points to help Allderdice push past a taleneted USO team.“We can’t stress enough the importance of playing great defense,” Allderdice coach Andre McDonald said. “We’ve always preached that to the kids in our program and it’s worked out tremendously for us.”As the league’s stingiest defense, the Dragons have given up a city-low 52.9 points per contest. They’ve maintained that title all of the last five seasons. So much so that during games, the students wear shirts with their team’s coined nickname, “Hawk D” on it, which also appears on their uniforms.“It’s really something that our entire student body, faculty, and team take great pride in,” McDonald added.Ishmael Swain was the city’s leading scorer in 2010 when the Dragons brought their first of three consecutive titles to Allderdice. But Dobbs led the pack with a game-high 17 points.The 6-foot-3 senior guard/forward leads the city in scoring, averaging 20.2 points a contest. He, and fellow senior and All-City first teamer Ben Mickens, have both received attention from Division-I programs.Mickens led the team with 14 rebounds and added 8 points for the Dragons.“Our seniors have been blessed with tremendous talent,” McDonald said. “If it wasn’t for the hard work, unselfishness, and pure dedication to this team, we would not be where we are today.”USO (16-6) was led by sophomore D.J. Porter, who shot 7-of-13 from the field and ended up with 15 points. Senior guard Dontae Forte added 10 for the Eagles. Their coach, Kevin Reid, was unreachable for comment.The success of the Allderdice basketball program, according to McDonald, is due to the undying support of the boosters’ organization always providing for the team, and to the students who always rally around them.“We have a great atmosphere for sports at Allderdice,” he said. “It’s no mistake that our football team appeared in its title game and that we’ve three-peated in ours. We have a tremendous following, a great support from our family and friends. That brings a great feeling to us as a team.”Allderdice will play in the PIAA Class AAAA first round March 10. USO advances to the PIAA play-in round and will take on the WPIAL’s third-place team.GIRLSA familiar face to the Lady Dragons’ success, Lanise Saunders led her team with a game-high 14 points to solidify a three-peat of their own.Syndnee Abernathy followed up with 12 points and senior guard Janay Bottoms added 10 points as Allderdice (21-3) pushed past Westinghouse, 49-46, on Feb 25 at Peabody.“I think both teams brought what they could and played their best,” Saunders said. “But (we) took it a step further and played like a family.”A 6-foot-2 post player, Saunders signed a National Letter of Intent with Division-II Gannon University earlier this year for a full athletic scholarship.“We got the win,” she said with pride. “But we don’t plan on stopping here. We plan to carry that exact same intensity into State competition.”Saunders carries a 4.2 GPA and has been the driving force behind the Dragons in their quest for a title. She added 11 rebounds to her point total and has become one of the main producers of the double-double in the city.Westinghouse (19-5) was led by Cassandra Flowers who had a team-high 10 points.Allderdice, which also defeated the Bulldogs in the final game last year, advances to the first round of the PIAA Class AAAA tournament on March 9.(Malik Vincent can be reached at mvincent@newpittsburghcourieronline.com or on Twitter @malikvincent.)last_img read more
