How long can it take for post-vaccination symptoms to occur after Fluenz Tetra?

Some post-vaccination reactions may occur shortly after vaccination, a few hours after vaccination, others may develop within 2-3 days after vaccination. It is often observed that, for example, elevated body temperature appears within 24 hours after vaccination and resolves within 2-3 days. Formally, however, the definition of a post-vaccination reaction reaches all health disorders up to 4 weeks after vaccination. Stuffy nose or watery runny nose is a possible side effect of Fluenz Tetra - it affects more than 1 in 10 people. Fever may occur less frequently - in less than 1 in 10 people. It cannot be excluded that the described symptoms on the third day after vaccination are related to the administration of the vaccine. However, there is also the possibility that it is a vaccine-independent, classic infection.
