H1N1 Vaccine

Here is an update on the Pandemrix vacccination program for front liners in Malaysia dated 14 January 2010, released by the National Pharmaceutical Control Bereau, Malaysia Minisrty of health.
The H1N1 vaccine Pandemrix® has been distributed in Malaysia from 1st of November 2009 and to date, the Malaysian Adverse Drug Reaction Advisory Committee (MADRAC) has received 20ADR reports related to Pandemrix®.

...Of the 20 reports, only 1 report was clearly recognised as a serious adverse event as the patient developed an anaphylaxis reaction.

The most frequently reported adverse events were minor which included injection site reactions,
lethargy, fever, headache, nausea and minor skin reactions.

From the Summary of Product Characteristic (SPC), the following adverse reactions which have been reported are considered as

very common (>1/10) for headache, injection site reaction, fever and lethargy and

uncommon (1/1000 to 1/100) for rash, nausea, and abdominal cramps.

... Up until 4th of December 2009, a total of 7516 doses of the vaccine have been given to the
front-liners of the Malaysian Ministry of Health. Since Pandemrix® is a new vaccine, it is advised that all healthcare providers report all adverse events following immunisation (AEFI) including the minor and known reactions.
Read the full report here . Still, receiving it would be relatively safe, unless contraindicated.


Seems like the highlight of the H1N1 is beginning to make headlines in the last few weeks. Even the Thomas Cup preparation was not spared.

What ever it is, it is always better to keep our hygiene in a top notch condition, WASH HANDS, limit our movement mingling unnecessarily in public places, wear face mask for those who have symptoms of influenza and practice good cough etiquette.  This applies not only to the H1N1 virus, but also in all infectious diseases.

Clinics that provide antiviral treatment (Oseltamivir) are listed here.

Private clinics claiming to provide H1N1 vaccination to the public is NOT true. They are stocked up with seasonal influenze vaccines only. The seasonal influenza vaccine and the H1N1 specific vaccines are different altogether.
