dTaP/IPV (4 in 1) vaccine - About the 4 in 1 vaccine
The 4-in-1 vaccine (also known as the dTaP/IPV vaccine) helps protect against four serious diseases: Diphtheria, tetanus, pertussis (whooping cough) and polio. The ‘4-in-1’ vaccine is highly effective and boosts immunity to diphtheria, tetanus, pertussis (whooping cough) and polio infections.
The 4-in-1 vaccine boosts the protection from the 6-in-1 vaccines they had as babies (which included protection against diphtheria, tetanus, whooping cough, polio, Haemophilus influenzae type b (Hib) and hepatitis B).
Since the protection from baby vaccinations can fade over time, it is important for your child to get their 4-in-1 vaccine.
The 4-in-1 vaccine helps keep children safe and helps protect communities from these diseases and the serious health complications they can cause.
