Clearbridge Medical 4-Valent Influenza Vaccine

Antigenic drifts (minor changes) of seasonal influenza viruses will lead to emergence of new strains. New strains appear from time to time and at irregular intervals. This explains why the World Health Organization will make recommendations on the formulation of influenza vaccine every year.

Seasonal influenza is different from influenza pandemic. The occurrence of influenza pandemic results from the emergence of a pandemic strain, which appears when antigenic shift (major change) occurs in a novel influenza virus resulting in efficient human-to-human transmission. People will have very little or no immunity to the virus, which causes the virus to spread more rapidly and extensively than a seasonal influenza virus.

Seasonal influenza vaccination

The vaccine is safe and effective in preventing seasonal influenza and its complications.
Influenza can cause serious illnesses in high-risk individuals and even healthy persons. Given that seasonal influenza vaccines are safe and effective, all persons aged 6 months or above except those with known contraindications are recommended to receive influenza vaccine 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.
