A number of new drugs become available for the treatment of opportunistic infections called AIDS. Burroughs Wellcome lowers the price of AZT by 20%. A new antiretroviral drug, dideoxyinosine (ddI), is authorized by the FDA for use by patients intolerant to AZT.

The American trial of AZT in early treatment is stopped, because it is decided the drug used had been shown to significantly slow progression of the disease, even though there had been no study to confirm or disconfirm this.

In February, Dr. Duesberg publishes "HIV and AIDS: Correlation but not Causation." in the Proceedings of the National Academy of Sciences.

Scientific journalist Jad Adams publishes the book AIDS: The HIV Myth in England.
