What Is a Moderna Booster Dose? A Moderna booster dose is an additional shot of the Moderna COVID-19 vaccine, given after your initial vaccination series. Its purpose is to restore or increase immunity that may have decreased over time. Primary series: Usually two doses of Moderna, spaced apart. Booster dose: A follow-up shot to “boost” your immune system against newer variants. Bivalent booster (introduced in 2022): Targets both the original strain and newer variants like Omicron. Updated booster 2025: Designed to address circulating strains and improve long-term immunity. Why Do You Need a Moderna Booster Dose ? Immunity from the original vaccine series naturally decreases after a few months. The virus also evolves, making older antibodies less effective. The Moderna booster dose helps: Increase antibody levels – providing stronger protection against COVID-19. Reduce risk of severe illness – protecting high-...

 One of the fastest and most effective tools for identifying infectious diseases is the antigen detection test . These tests have gained significant attention, especially during the COVID-19 pandemic, but their use extends far beyond that. From influenza to strep throat, antigen tests are revolutionizing how we detect and control outbreaks. What Is an Antigen Detection Test? An antigen detection test is a diagnostic method used to identify the presence of specific proteins (antigens) on the surface of a pathogen, such as a virus or bacteria. Unlike molecular tests that look for genetic material (DNA or RNA), antigen tests detect these protein markers to quickly confirm infection. For example: A COVID-19 antigen test checks for proteins from the SARS-CoV-2 virus. A strep throat antigen test detects Group A Streptococcus proteins. Influenza antigen tests identify influenza virus proteins. Because antigens are unique to each pathogen, antigen detection...
