CDC urges second COVID dose for over 65 and immunocompromised

In the United States, the Centers for Disease Control and Prevention (CDC) recently recommended that individuals who are immunocompromised and aged 65 or older should receive a second dose of the updated COVID-19 vaccine for the 2024-2025 season. This advice comes as part of health authorities' efforts to address the ongoing challenges posed by COVID-19, particularly during the upcoming fall and winter months when cases are expected to surge. The CDC specifies that the second dose should be administered six months after the first dose. Additionally, for those who are moderately or severely immunocompromised, the CDC allows for the possibility of further doses in consultation with their healthcare providers. This year's updated vaccines, authorized by the Food and Drug Administration (FDA), were designed to target the KP.2 variant of SARS-CoV-2, and they are expected to also provide immunity against other emerging strains. The ongoing process of adapting vaccines annually reflects the effort of health authorities to maximize effectiveness against evolving viruses. The recommendations emphasize the importance of vaccination as a critical measure to protect vulnerable populations from severe COVID-19 outcomes. Despite the recommendations, a survey has shown a concerning trend, with less than half of Americans indicating plans to receive their COVID or flu shots this season. This hesitation poses risks as healthcare officials warn against potential increases in COVID-19 infections. The CDC has highlighted that vaccination not only protects against severe disease but also reduces the risk of long COVID, underscoring the need for increased public awareness and participation in vaccination efforts.
