A federal panel gave the go ahead for doctors to start using the child friendly nasal spray flu vaccine again on Wednesday (file image)The Centers for Disease Control and Prevention has spent the last five months urging everyone over six months of age to get one of the two flu shots it recommended this year.But, as officials announced last week, each of these was only about 36 percent effective against the flu this season.The shots were particularly weak protection against the aggressive H3N2 strain that has dominated the 2017 2018 season, preventing only 25 percent of adults from getting the bug.The shot was somewhat better at protecting children about 59 percent effective though they undoubtedly would prefer the spray.Unlike most countries, neither of the flu shots recommended in the US this season contained any live attenuated influenza virus (LAIV), the active ingredient in FluMist.RELATED ARTICLES Previous 1 Vaccinating pregnant women IS safe for babies, first. Why the flu vaccine was a flop: It depends too much on each.Share this article ShareFluMist, the only nasal spray vaccine approved in the US, was found to be relatively ineffective in recent years, particularly against the H1N1 strain of the flu that was responsible for the majority of illnesses during the 2015 2016 season.In order for a live virus vaccine to be safe and effective for use humans, it has to strike just the right balance between replicating enough to activate an immune response, but not enough to cause the illness itself.FluMist’s past poor performance against H1N1 may mean that scientists at AstraZeneca, which makes the vaccine, picked proteins that were too weak.The company presented a data from a small study to theAdvisory Committee of Immunization Practices during its meeting today.WHAT ARE THE FLU STRAINS HITTING THE US THIS YEAR?There are many different types of flu circulating around the world, but four main types are being seen, or are set to emerge, in America this winter.H3N2 Dubbed ‘Aussie flu’ after it struck Australia hard last winter, this strain is more likely to affect the elderly, who do not respond well to the current vaccine. This is one of the most common strains seen so far this winter.H1N1 This strain known as ‘swine flu’ is generally more likely to hit children, who respond well to vaccination.
The rough is a whole other problem, as are other obstacles on the course, such as sprinkler heads. The rough is always going to be thick and hard to play out of, but a heavy, wet rough makes it almost impossible for a golfer to do much more than simply attempt to chip back onto the fairway. Sprinkler heads, which are positioned all over the course, will have an adverse affect on a ball that happens to hit them..
