Fortunately, the people recovered.. but it serves as an example of why it pays to be cautious. If they can't foresee the short term risks, then what do they know about the long term risks of a bad batch of vaccine? |
Even with the higher rate of adverse reactions that batch was still safer than not getting vaccinated though; that's still only about a 1 in 30,000 rate of adverse reactions. In the big picture 6 people having an allergic reaction (from which they recover) isn't a huge number, particularly compared to the number of people getting really sick from the flu. The question is why there was a higher rate of allergic responses to this batch, which they'll hopefully resolve (perhaps it wasn't purified as much leaving more egg proteins in - but that's pure speculation on my part).
There's no reason to expect long term risks - allergic reactions are a short-term response, and there's nothing in the vaccine that will stay in your body long-term.
