Post-Vaccination Fever & Flu Vaccination Advice

Vaccinated individuals, parents and carers should be advised that flu vaccines may cause a mild fever which usually resolves within 48 hours.

This is a common, expected reaction and isolation is not required unless COVID-19 is suspected.

Feeling generally unwell, shivery, achy and tired are also commonly reported symptoms following flu vaccination. These symptoms usually disappear within one to two days without treatment but paracetamol can be given if necessary to relieve any of these symptoms.

As has always been recommended, any fever after vaccination should be monitored and if individuals, parents or carers are concerned about their, or their child’s health at any time, they should seek advice from their GP or NHS 111.

If someone develops fever post vaccination, this would normally be within the first 48 hours following vaccination AND usually resolve within 48 hours. This is a relatively common, expected reaction, and self-isolation and testing for COVID-19 are not required unless COVID is suspected based on other clinical criteria such as cough and/or loss of taste or smell.

If fever starts beyond 48 hours post vaccination OR persists beyond 48 hours or an individual develops other COVID-19 related symptoms, then they should self-isolate and be recommended to have a test for COVID-19. Testing for COVID-19 may also be considered at any time following clinical assessment, or if there are other considerations such as being a close contact of a case or part of a cluster.
