Third Primary Doses Covid-19 Vaccine

3rd Primary Doses Covid-19 Vaccine

The difference between third primary doses and boosters.

People with a weakened immune system are being offered a 3rd dose of a coronavirus (COVID-19) vaccine. This is also known as a 3rd primary dose.

If you had a weakened immune system when you had your first 2 doses, the vaccine may not have given you as much protection as it can for people who do not have a weakened immune system.

A 3rd dose may help give you better protection.
