Each year a new flu vaccine is developed using a complicated system of tests which are used to determine exactly which strain of the common flu is likely to spread through the population. The flu strain often changes quite drastically each year but this year medical analysts are saying that the strain might not be changing hardly at all.
This month the companies responsible for developing and making the flu vaccines announced that the studies being conducted show that the flu strain is nearly identical to last year’s strain. What this means for millions of people is that a flu vaccine this year simply won’t be necessary because the immune resistivity will be carried over from the previous flu shot.
Of course government health agencies are still encouraging all people at risk for the flu to prepare for a flu shot as flu season approaches. Fortunately the vaccine companies have also announced that they will be producing a record number of flu vaccine doses; as many as 173 million doses are expected to be prepared for distribution as flu season approaches which means a record number of people will be able to receive the vaccine if desired.
Despite what government health agencies are saying doctors are encouraging only those highly at risk to receive the flu shot. Because of the fact that last year’s flu shot will still be nearly 100% effective doctors say there is no need to waste time, money, or resources to re vaccinate those who are already protected.
