This winter season of the United States has not been and will not be as devastating as the historic season in which 80,000 Americans were killed last year. It can lead to the fact that belated people will want to give up the idea of getting a vaccine against influenza. But the new report from the Centers for Disease Control and Prevention must hope that you will be convinced otherwise: it turns out that the shot this year is almost twice as effective as last year to prevent the flu.
The report was published in the CDC Weekly Report on Mortality and Mortality. It provides an early assessment of the effectiveness of the influenza vaccine, based on the data of thousands of real patients who visited the doctor's office. According to the report, the vaccine is generally 47% effective against all influenza strains circulating this year; for children aged 6 months to 17 years, in fact it is 61% effective. It was considered to be only 8% effective for adults over the age of 50 years, but the authors believe that this estimate may be excluded due to the low number of old patients in their sample.
This may not seem like a huge number, but the influenza virus is known to be difficult to vaccinate against, since it can quickly mutate. And on average, the current vaccine is equally effective (albeit at the lower end), since any other year would be against similar strains. Moreover, it is much stronger than the vaccine last year, which was only 25 percent effective against the linear, more powerful strain H3N2 this season. for years when the shot is less effective. According to studies provided by the authors, the vaccine for 2017-2018. Avoid 7.1 million cases of influenza, 3.7 million visits to doctors, 109 000 hospitalizations and 8000 deaths. And this could be even better when the vaccine was received by more than 37% of adults and 58% of children
. For now, the vaccination coverage forecast will be higher than last year, which is high. If you do not have to get the vaccine, it's not too late! The authors said doctors should continue to offer the vaccine, as the season of flu is still ongoing and there may be other influenza strains circulating later this season. This year you can even avoid a painful shot because the nasal spray vaccine is once again recommended for all age groups. So, if you end up getting sniffles to this, do not charge the vaccine (it can not give you a flu, although it may have some, almost always what, side effects). Just vaccinate already.
