Why I am still suffer fever and cough after getting flu shots?
Print Edition
Getting vaccinated does not guarantee complete immunity from the flu, but it definitely reduces the risk of infection, severe symptoms, complications and even death. It takes time for the vaccine to generate protective antibodies. If you’re exposed to the virus before vaccination takes effect, you could still catch the flu.
Flu-like symptoms such as fever, runny nose and cough can also be caused by other illnesses like the common cold, pneumonia or adenovirus, which the flu vaccine doesn’t prevent.
If only a few individuals in a household, workplace or school are vaccinated, it’s hard to establish herd immunity. This allows the flu virus to continue circulating, potentially reducing the effectiveness of individual vaccinations. Widespread vaccination is key to both personal protection and reducing the overall impact of flu in the community.
