H2N2: The Next Threat?
You're watching multisource health news analysis from Newsy
Just as the world breathes a sigh of relief after the H1N1 flu pandemic, researchers say a single mutation could make this flu even more dangerous--and eerily familiar.
Reporter: “An older, mid-20th century virus could come roaring back for the northern hemisphere winter. The so-called Asian influenza, a H2N2 strain, first appeared in 1957 and killed one to four million people despite a major vaccination campaign.”
Geneva Scientists recently confirmed that H2N2 is circulating among birds and pigs and could easily spread to humans. The biggest concern is, those under 50 have little to no immunity against the killer flu.
So why haven’t worl governments sounded the alarms? It’s all about vaccine costs. In response to the H1N1 outbreak, many nations stockpiled vaccines at a huge cost, causing some to cry foul.
Reporter: “The debate rages over whether pharmaceutical companies deliberately mislead governments about the seriousness of swine flu to make them stockpile vaccines...
Agency Worker: "Britain has spent a fortune on preparations.”
But a writer for Nature.com suggests failing to prepare for H2N2 could have much higher costs in the long run.
“An influenza pandemic is likely to cost far more and create a much greater health burden than a well-planned pre-emptive programme ... The inevitable delay in distributing the vaccine would allow the virus to spread, kill more people and potentially mutate to the point of being able to evade people's immune systems.”
But a doctor on KCPQ disagrees and believes flu season will end without
controversy.
“It has been a very ordinary flu season which means a lot of people get it a lot of people are sick but no more so than previously in previous years. We kind of remember that there was a big outbreak of the 2009 H1N1 swine flu. We have not seen that.”
And a blogger for Examiner doubts there’s and ulterior motive behind the call for vaccination, and points out: millions of lives at risk is no laughing matter.
“[T]he call to action by vaccine specialists is only a step to help bring into awareness that no disease or virus should be taken lightly, especially if it has existed in the past ... it seems that advanced warnings of these deadly viruses has become a norm...”
Researchers claim the H2N2 vaccine from the 60s could still be used alongside standard vaccines as a preventive measure for future outbreaks.
