How long does it typically take for a vaccine to take effect? Specifically the vaccinations for a one year old.
In general, it takes about two weeks after getting a vaccine for antibodies to develop in the body that protect against the diseases the vaccine is made to protect against.
Most vaccines require more than one dose over time to produce immunity and long-lasting protection. The number of doses needed depends on the type of vaccine. You can learn more about this here.
