Researchers Warn Some Covid 19 Vaccines Could Increase Risk Of HIV!  Some of the Covid-19 vaccines currently in development could increase the risk of acquiring HIV, warned a group of researchers in the The Lancet medical journal Monday, potentially leading to an increase in infections as vaccines are rolled out to vulnerable populations around the world. Lots of vaccines make use of modified viruses to transport material into the human body. Many make use of a modified adenovirus to do this, a virus which is usually harmless except the ability to cause the common cold. Some of the leading candidates for a Covid-19 vaccine, including those from Johnson & Johnson and  AstraZeneca, use adenoviruses as vectors. There is no evidence that those vectors increase the risk of HIV infection. The authors said they went public because Ad5 vaccines for Covid-19 might soon be tested in populations with high HIV prevalence. Lawrence Corey, one of the authors who now co-leads the Covid-19 prevention network in the U. S. that is testing vaccines on behalf of the NIH, told Science that if he were in a sub-Saharan African country, where there’s a high prevalence of HIV, “I don’t see why I would pick an Ad5 vector (vaccine) when there are many other alternative choices.”Could certain COVID-19 vaccines leave people more vulnerable to the AIDS virus?
