Dr. When the new disease AIDS burst onto the scene in the early 1980s and the virus that caused it was discovered in 1983-84, it was only natural to think that the research community would be able to develop a vaccine for it. At a now famous press conference in 1984 announcing HIV as the cause of AIDS, then U.S. Secretary of Health and Human Services Margaret Heckler predicted that a vaccine would be available in two years. Well, it is now 37 years later and there is no vaccine. The rapidity of COVID-19 vaccine development. Distribution puts the lack of an HIV vaccine in stark contrast. The problem is not failure of government. The problem is not lack of spending. The difficulty lies in the HIV virus itself. In particular, this includes the remarkable HIV strain diversity and the immune evasion strategies of the virus. So far there have been five large-scale Phase 3 vaccine efficacy trials against HIV, each at a cost of over US$100 million. Through observations they determine what the average tendency is. Then they express a slightly more extreme opinion than the perceived average opinion Isenberg86 ; DeGroot74 ; Sunstein02 . There is clear evidence for this assumption from numerous experimental studies Isenberg86 ; BaronRoper76 ; Myersetak77 . Moreover, due to the homophily phenomenon McPhersonetal01 , which states that people are more likely to interact with those who are similar to them with respect to socio-economic background Currarinietal09 as well as attitudes Dandekaretal13 , people are more likely to socially compare themselves to similar peers. Group polarization phenomena are also explained drawing on the Persuasive Argument Theory, which states that people are more likely to change their opinion when presented with persuasive arguments. Group polarization can occur when the group discourse is manipulated through biased information or misinformation, exposing a group to false persuasive arguments Isenberg86 ; Sunstein02 ; Burnstein82 . The theory is strongly supported by empirical evidence from numerous experimental studies Isenberg86 ; EbbsenBowers74 ; VinokurBurnstein78 . cats
