Influenza Vaccine

About

Influenza vaccines, commonly known as flu shots, are designed to protect against infection by influenza viruses. They are recommended annually for everyone aged 6 months and older to prevent flu and its complications. The vaccines come in different forms, including inactivated, attenuated, and recombinant types, and are administered via intramuscular, intranasal, or intradermal routes. Each year, new versions of the vaccines are developed to keep up with the rapidly changing influenza viruses. The flu vaccine is crucial for preventing influenza-related illnesses, hospitalizations, and deaths. It not only protects the individual but also helps prevent the spread of the flu within communities. Common side effects include soreness at the injection site, fever, and temporary muscle pains. Despite these mild side effects, the benefits of vaccination far outweigh the risks, especially for high-risk groups such as the elderly, pregnant women, and those with certain health conditions. Vaccination typically takes two weeks to become effective and is recommended by the end of October to prepare for the flu season.
