Current seasonal flu vaccination does not confer any protection against the Influenza A (H1N1) virus.
However vaccination is still necessary because if you come down with flu like symptoms after vaccination, then there is higher alert as to whether you may have contracted Influenza A (H1N1) or avian flu. Early treatment can then be initiated.
Vaccination is not advisable for the following groups of people
- Age <6 months
- 1st trimester of pregnancy. Vaccination is alright to be given for 2nd and 3rd trimester
- Egg allergy such as urticaria, angioedema or anaphylaxis
- Allergy to previous influenza vaccination such as urticaria, angioedema or anaphylaxis
- Develops Guillain-Barre syndrome (weakness or paralysis of muscles) from previous influenza vaccination. This risk is very rare and is estimated at 1 or 2 cases per 1 million vaccinated patients.
- Acute illness with fever. Should delay vaccination till after recovery from illness
Adults and previously vaccinated children only require single dose vaccination.
Previously unvaccinated children, age > 6 months to 9 years, should receive 2 doses given at least 1 month apart.
You may get mild soreness or fever after 1-2 days from the vaccination.
