See the up – swine flu is on the input

Those included in risk groups should get vaccinated against the flu

A broader vaccine against the approaching seasonal influenza to reduce the risk of a repeat of the flop from last year.

this time the experts think that swine flu is making a comeback on a broad front.

As a letter in the mail will the seasonal flu back to the northern hemisphere each höstvinter. The experts at the world health organization (WHO), beat their heads together to predict which strains will get the strongest foothold the next time, and thus which should be included in the vaccine before the contagion begins in earnest.

the Problem is that the production of the vaccine takes six months, and the decision must therefore be taken far in advance.

– It is a huge puzzle that is added each year, in February for the northern hemisphere and in september for the southern. We have several thousand strains to take a position when we choose out some few that shall be included in the vaccine, " says Mia Brytting, head of the unit for laboratory virus - and vaccinövervakning on Folkhälsomyndigheten.

Protects against further strain.

Before the 2017\\u002F2018 bet WHO on three different virus strains in a trivalent vaccine, but not strain B\\u002FYamagata which turned out to be the one who dominated. Many who were vaccinated was, therefore, still sick during the season 2017\\u002F2018.

– A consequence of it is that nearly all county councils now have switched to the fyrvalenta vaccine that contains four strains, the two B-linjetyperna and two A subtypes, " says Mia Brytting.

the swine Flu feared in years

prior to this season expect Folkhälsomyndigheten with A(H1N1), popularly known as swine flu, becomes the dominant, since it was now three years since the last wave had swept over Sweden.

– A(H1N1) virus has not been circulating in Sweden for the past two years to any great extent, therefore, has the immunity started to wane. If it now becomes the year's vaccine to protect very well, " says Mia Brytting.

Folkhälsomyndigheten calls on those in at risk groups to get vaccinated against this year's flu. The vaccines will begin to be given on 6 november.

The so-called swine flu, made the admission in 2009 and caused a number of deaths in Sweden.

" When was this trunk new in the world. It had changed so much that it was classified as a pandemic strain, " says Per Follin, county medical officer in Stockholm county.

Then came in all haste to create a pandemic vaccines, who only took the strain, the H1N1, and was equipped with a so-called förstärkarsubstans. We have not now anymore, now we have a combination vaccine in which the four different viruses are included. So we hope we will have a much better protection this season against H1N1.
