when did the swine flu vaccine come out?
november 2009
since november 2009, 14 deaths as a result of swine flu in northern ireland have been reported. the majority of the victims were reported to have pre-existing health conditions which had lowered their immunity. this closely corresponds to the 19 patients who had died in the year prior due to swine flu, where 18 of the 19 were determined to have lowered immune systems. because of this, many mothers who have just given birth are strongly encouraged to get a flu shot because their immune systems are vulnerable. also, studies have shown that people between the ages of 15 and 44 have the highest rate of infection. although most people now recover, having any conditions that lower one's immune system increases the risk of having the flu become potentially lethal. in northern ireland now, approximately 56% of all people under 65 who are entitled to the vaccine have gotten the shot, and the outbreak is said to be under control.

there was concern in mid-2009 that, should a second, deadlier wave of this new h1n1 strain appear during the northern autumn of 2009, producing pandemic vaccines ahead of time could turn out to be a serious waste of resources as the vaccine might not be effective against it, and there would also be a shortage of seasonal flu vaccine available if production facilities were switched to the new vaccine. seasonal flu vaccine was being made as of may 2009, according to webmd. the news site added that although vaccine makers would be ready to switch to making a swine flu vaccine, many questions remained unanswered, including: "should we really make a swine flu vaccine? should we base a vaccine on the current virus, since flu viruses change rapidly? vaccine against the current virus might be far less effective against a changed virus – should we wait to see if the virus changes? if vaccine production doesn't start soon, swine flu vaccine won't be ready when it's needed."
