New RSV vaccines are now available to help prevent serious infection in people over 60. Doctors explain the RSV vaccine and its side effects in older adults.
It was determined that fever was the most common systemic adverse reaction, but most of the fever resolved within 2 days after vaccination. The 15 μg group induced the highest titre of neutralising antibodies, which was about twofold more than the antibody titre of convalescent patients with COVID-19.
The thrombosis events associated with the COVID‑19 vaccine may occur 4–28 days after its administration and mainly affects women under 55.

Causes of breakthrough infections include biological factors in the recipient, improper administration or storage of vaccines, mutations in viruses, blocking antibody formation, and other factors. For these reasons, vaccines are rarely 100% effective. A 2021 study found the common flu vaccine provided immunity to the flu in 58% of recipients. [6]
