People aged 18 to 64 years old

In adulthood, it is important to ensure persistant protection against vaccine preventable diseases. The following information provides information on vaccines for persons aged 18 to 64.

Influenza

As serious influenza can occur even in healthy individuals, members of the public can consult their family doctors to receive seasonal influenza vaccination for personal protection. Usually, it is suggested that vaccination should be received in autumn every year. About 2 weeks after vaccination, the body will develop a sufficient level of antibodies to protect against influenza virus infection.1

The Scientific Committee on Vaccine Preventable Diseases recommends persons aged 50 or above to receive the seasonal influenza vaccination to protect from infection and its complications.
 

Pertussis (Whooping Cough)

Getting tetanus-diphtheria-acelluar pertussis (Tdap) vaccine is especially important for families with young infants. The Scientific Committee on Vaccine Preventable Diseases recommend vaccination to be anytime in the second or third trimester of pregnancy, which allows antibody transfer from mother to the foetus. It is also important that those who care for infants are up-to-date with pertussis vaccination. Health data have shown that, when the source of pertussis could be identified, mothers were responsible for 30-40% of infant infections and all household members were responsible for about 80% of infections.3

Women who are planning a pregnancy, post-delivery or other family members may seek for advice about pertussis vaccination from their family doctor.

Hepatitis B

Hepatitis B is considered an occupational hazard for health workers and vaccination is recommended for those people working in healthcare settings. Vaccination is also recommended for individuals who may take part in high risk activities like unprotected sex with people with chronic HBV infection, persons who inject drugs or travelers who have not completed their hepatitis B vaccinations, who should be offered the vaccine before leaving for endemic areas.4
