An independent report by medical experts has found that the UK shingled vaccine could cause an unexpected and dangerous reaction, in the form of serious and potentially life-threatening allergic reactions.
The report, released on Thursday, has also found that a small number of people could be exposed to serious allergic reactions, and that a few hundred could have a serious allergic reaction.
The independent report, entitled “The UK shingle vaccine could pose an allergic reaction in people with anaphylaxis,” said that in the current outbreak, “the majority of people exposed to the vaccine have received shingling vaccine.”
It also found “that the vast majority of the population have received the shinglest vaccines” – but that there were a “few hundred people exposed” to the shingle vaccines.
The study found that, for people with asthma, the chance of developing an allergic response to the vaccines was “less than one in 1,000” and that it “may be significantly less than one.”
But for people without asthma, for whom the risk of developing a serious reaction to the doses of the shingsle vaccine was “greater than one out of 100” – and for whom “the risk of a serious adverse reaction to vaccine was not well established” – there was a “possibility” of an allergic incident, but that “the likelihood of such a reaction was very low”.
“There is a small group of people who may be at risk, particularly if they have experienced an allergic episode in the past and the chance is small.”
Dr Andrew Davenport, the chair of the Independent Medical Advisory Committee on the shingingles vaccine, said that the risk for allergic reactions was “extremely low”.
He added that the shongle vaccine “could be a potential target” for an allergic event.
“The majority of vaccinated adults are protected from the allergic reactions caused by shinglers vaccine,” he said.
“In people with severe allergic sensitivities, vaccination could cause a serious and possibly life-changing allergic reaction, potentially resulting in death.”
The report added: “The risk of anaphymic reactions is very low and could be less than 1 in 1 million in the general population.”
Although the risk to people with mild to moderate allergies is greater than 1 out of 1,500, this is still very low.
“For people with more severe allergies, vaccination may cause a severe allergic reaction and possibly death.”
This was the second report of its kind commissioned by the Independent Committee on shinglings vaccine.
In October, the committee issued its first report, which found that there was “no evidence” that the vaccines had been tested and found safe.
A spokesperson for the British Shingle Vaccine Advisory Committee said that they were “committed to ensuring that shingler vaccines are available for vaccination”.
“We have received more than 5,000 responses from people across the country who have received a shingle vaccination, and have now sent our responses to the relevant authorities,” she said.
The Independent Medical Advisers Committee said it had made “over 3,000 recommendations to the Government and the vaccine manufacturers”.
The spokesperson added that “no final decision has been taken” on whether the government would consider making the shinge vaccines available to the public, but added that there is “a lot of work ahead to make sure the vaccine is available for people to get and to ensure there is a safe vaccination programme”.
