Vaxigrip Tetra: Quadrivalent Inactivated Influenza Vaccine (Split Virion)
What this protects against
● Four Flu Strains: Protects against two Influenza A strains ($H1N1$ and $H3N2$) and
two Influenza B strains, providing broader coverage than older trivalent vaccines.
● Severe Respiratory Illness: Reduces the risk of high fever, body aches, and debilitating
fatigue caused by seasonal influenza.
● Serious Complications: Helps prevent flu-related pneumonia, bronchitis, and the
worsening of chronic medical conditions like asthma or heart disease.
Why it’s essential
● Annual Update: Because the flu virus evolves rapidly—similar to the variations you
monitor in your wastewater research—getting vaccinated every year is the only way to
stay protected against the currently circulating strains.
● Community Shield: Protecting yourself also protects vulnerable groups around you,
such as infants, the elderly, and those with weakened immune systems who are at
higher risk of hospitalization.
● Productivity: Prevents the loss of work or school days due to seasonal illness
outbreaks in Lagos.
