H1N1 vaccine side effects?

From the complaints made by those who have taken the H1N1 vaccination (some side effect reported to be fever, rashes, nausea and vomiting), there is nothing mentioned, however, which of the two type of the vaccines that caused most the side effect.

There are two H1N1 vaccines approved by the Health Sciences Authority (HSA):
The Health Sciences Authority (HSA) has approved the following two H1N1 influenza vaccines on 9 and 15 Oct 2009 respectively:

i] Panvax H1N1 Vaccine by CSL Limited, Australia
ii] Pandemrix H1N1 Injection by Glaxo Smithkline Biologicals

Panxax and Pandemrix contain the A/California/7/2009 (H1N1) viral antigen and are able to induce an adequate immune response. Both vaccines were assessed to have met the criteria for quality, safety and efficacy for the use by adults above 18 years against the current circulating influenza A(H1N1) virus in a pandemic situation.

These vaccines will be distributed by the Ministry of Health to local doctors and clinics, and should be used in accordance with the official guidance.

Fever, rashes, nausea and vomiting are some of the complaints that have been made by those who have taken the H1N1 vaccination.

As of Sunday the Health Sciences Authority has received 27 reports of adverse affects since the pandemic flu jab became available on Nov 6.

It is not clear how many people here have used the vaccine although more than 300,000 have placed orders.

A HSA spokesman said the cases reported so far were 'non-serious anticipated side effects'. 'These reactions are commonly expected from all flu vaccines and most of these reactions are resolved within a few days.'

As pandemic vaccines are usually administered on a large scale, special safety issues may arise which had not been dectected due to a lack of clinical trials.

The HSA's vigilance branch, which monitors vaccine safety on the national level, has intensified its surveillance activities to closely monitor the safety of the H1N1 vaccines that are available here.

From Straits Times, "Flu jab side effects reported".

An unusual number of severe allergic reactions to swine flu vaccinations have been recorded in Canada, where a batch of the vaccine from GlaxoSmithKline has been recalled, the WHO said on Tuesday.

World Health Organisation spokesman Thomas Abraham told AFP: 'The Canadian authorities are conducting the appropriate investigations on the vaccines' and 'recalled a batch of vaccine from GSK'. 'We need to understand what happened in Canada,' he added.

Mr Abraham said, however, that the WHO had not changed its recommendations regarding swine flu vaccines.

Last week, the WHO said checks on many of the 30 deaths recorded following mass pandemic flu vaccinations had so far ruled out a direct link to the vaccines.

The fatalities made up a minute fraction of at least 65 million doses of swine flu vaccines which have been administered, said the WHO, citing data from 16 countries.

For every 10,000 doses of vaccines administered, only one report of adverse effect had been logged. Of every 100 reports of adverse effects, five are serious cases such as death, according to the WHO.

From Straits Times, "Severe reactions to flu vaccine".

The Health Sciences Authority said on Tuesday that 27 cases of adverse reactions suspected to be associated with the use of the H1N1 vaccine have been reported so far.

But "these reactions are non-serious anticipated side effects such as fever, rashes, flu-like symptoms, headaches, nausea and vomiting", said an HSA spokesperson. "These reactions are commonly expected from all flu vaccines and most of these reactions are resolved within a few days."

MediaCorp understands that one Mrs Wee - a 37-year-old supply chain assistant manager - suffered serious side-effects when she, her husband and maid took the jabs at Tan Tock Seng Hospital on November 7.

She had "insect bite-like" marks on her left forearm that spread and became red blotches "all over her limbs" within a day. Her wrists, elbows, knees and ankles also swelled to twice their sizes, making it painful for her to walk.

Mrs Wee is believed to be the first case of someone suffering from serious side effects after taking the H1N1 vaccine jab since the doses were made available earlier this month.

Even as the H1N1 vaccine has a "relatively good safety profile", the World Health Organisation told AFP an "unusual number of severe allergic reactions" to the H1N1 vaccine have been reported in Canada.

"The Canadian authorities are conducting the appropriate investigations on the vaccines" and "recalled a batch of vaccine from GlaxoSmithKline (GSK)", said a spokesperson.

A spokeswoman for the UK drugmaker also told Bloomberg that Canadian doctors should hold off on using one particular batch of GSK's swine flu vaccine temporarily while the company probes reports of higher-than-expected occurrences of a side effect known as anaphylaxis - where one suffers from swollen tongues and throats, leading to breathing difficulties and dizziness. Typically, it affects one in 100,000.

HSA said it is closely monitoring the safety of the H1N1 vaccines that are available in Singapore, and doctors are "strongly encouraged" to report all cases where patients have suffered serious side effects due to the jabs.
