Becoming seropositive for COVID-19 antibodies can occur due to either infection with COVID-19 itself or due to becoming vaccinated to COVID-19. [33] Being seropositive for COVID-19 does not intrinsically confer immunity or even resistance. However, higher rates of seroconversion are linked to greater clinical efficacy of vaccines.
People who participate in vaccine trials which test HIV vaccines may exhibit VISP for years or for the rest of their lives. [citation needed] A study done on participants in the HIV Vaccine Trials Network HIV vaccination studies showed that among 2176 HIV negative participants who received a vaccine, 908 (42%) had VISP.

In an interview with Yahoo News, Dr. Anthony Fauci discussed the state of HIV vaccine research after the recent failure of a late-stage trial funded by the National Institute of Allergy and ...
HIV vaccine development is an active area of research and an important tool for managing the global AIDS epidemic. Research into a vaccine for HIV has been ongoing for decades with no lasting success for preventing infection. [151] The rapid development, though, of mRNA vaccines to deal with the COVID-19 pandemic may provide a new path forward.
A shingles vaccine may contain a surprising benefit. Research from Oxford University suggests that the shingles vaccine, Shingrix, might delay the onset of dementia by five to nine months. Exactly ...
