[efoods]With millions of people being vaccinated against the virus there is a real risk that coincidental events will be seen as reactions to the jab, a paper in The Lancet said.
Experts at Cincinnati Children’s Hospital in America calculated the background rate of conditions that may be mistaken for vaccine reactions and warned that there is a risk people will shun the jab needlessly.
Only if these background rates are exceeded will it point to a potential problem with the vaccine.
Medical experts have been told to watch for any cases of Guillain-Barré syndrome during the flu pandemic as some research suggested there was a link between a flu vaccine used in America in 1976 and the condition, in which the body’s immune system mistakenly attacks part of the nervous system and can be fatal in rare cases.
