US CDC Recommends a Second Dose of This Year's COVID-19 Vaccine for Adults Over 65; Here's the Reason

The U.S. Centers for Disease Control and Prevention (CDC) has recommended a second dose of the updated COVID-19 vaccine for individuals over 65 and those with weakened immune systems, to be administered about six months after the first dose. Experts highlight that this vaccination helps prevent reinfection and reduces the risks of long COVID, which can lead to prolonged symptoms.

Flexible Dosing for Immunocompromised Individuals

 

The CDC's recommendations also include flexibility for individuals who are moderately or severely immunocompromised. These individuals may benefit from additional doses of the vaccine beyond the standard regimen, including three or more shots, as determined in consultation with their healthcare provider. This approach allows for tailored protection for those at higher risk of severe COVID-19 outcomes.

Updated Vaccines for 2024: Moderna and Pfizer Lead the Way

In August, the U.S. Food and Drug Administration (FDA) approved the updated COVID-19 vaccines from Pfizer and Moderna for the fall 2024 season. These vaccines are specifically revised to target the KP.2 variant of SARS-CoV-2, which has contributed to rising infection and hospitalization rates across the United States. This annual update process is part of federal health authorities’ strategy to enhance vaccine effectiveness against the evolving strains of the virus.

CDC Recommends Vaccination for All Americans

Continuing its annual advisory, the CDC has recommended that all Americans aged six months and older receive a dose of the 2024-2025 COVID-19 vaccine. This updated vaccine is intended to provide protection against potential COVID-19 surges expected in the fall and winter months. However, data from Ohio State Wexner Medical Center indicate that only about half of Americans plan to receive their COVID-19 and flu shots this season, highlighting a gap in public response to vaccination recommendations.

"Data continues to confirm the importance of vaccination to protect those most at risk for severe outcomes of COVID-19," the CDC emphasized in its latest release. "Receiving the recommended 2024-2025 COVID-19 vaccines can restore and enhance protection against the virus variants currently responsible for most infections and hospitalizations in the United States." The CDC also reiterated that the COVID-19 vaccine can help reduce the chances of experiencing long COVID symptoms.

Understanding Long COVID and Its Impact

Long COVID, or post-acute sequelae of SARS-CoV-2 infection, is a chronic condition affecting many COVID-19 survivors across the United States. This condition is marked by a wide range of symptoms—over 200, according to medical experts—that can persist long after the initial infection. Common symptoms include:

  • Extreme fatigue
  • Memory issues, often called "brain fog"
  • Dizziness or lightheadedness
  • Loss of taste or smell
  • Sleep disturbances
  • Shortness of breath
  • Severe cough
  • Headaches
  • Irregular heartbeat
