As in all areas of health and medicine, COVID-19 dominated the HIV treatment news this year. In the early days of the pandemic, POZ published a roundup of what people with HIV need to know about the new coronavirus (No. 1). At the time, small studies and anecdotal reports suggested that people living with HIV were not more likely to acquire the new coronavirus or to develop severe COVID-19 (No. 2).

In fact, there were some early hints that meds taken for HIV prevention or treatment might offer some protection against the new virus (the top POZ news story of the year) and antiretrovirals might be used to treat it; neither was confirmed in later research. As the year went on, larger studies suggested that people with HIV indeed might be more susceptible to severe COVID-19. See our year-end roundup HIV and COVID-19: What Do We Know Now?

As the first COVID-19 vaccines rolled out in December, questions arose about whether they’re safe for people with HIV (No. 4). Many asked how a coronavirus vaccine could be developed so fast while we still don’t have one for HIV. As scientists have learned over the past three decades, developing an HIV vaccine is a more difficult endeavor. But much research is underway (No. 6, No. 10, No. 16), including an experimental HIV vaccine that uses the same mRNA technology as the first two authorized COVID-19 vaccines (No. 8).

POZ readers also sought HIV cure news. Sadly, the first man cured of HIV, Timothy Ray Brown, died this year after a relapse of the cancer that led to his groundbreaking bone marrow transplant. But we heard about a man in Brazil who remains in long-term remission without antiretrovirals (No. 15) and an American woman whose own immune system may have cured her HIV (No. 3).

On the HIV treatment front, readers are concerned about the growing evidence linking modern antiretrovirals to weight gain (No. 9, No. 18). People with HIV are eagerly awaiting the first long-acting injectable treatment, which has already been approved in Canada and Europe (No. 13). Long-acting cabotegravir is also highly effective for pre-exposure prophylaxis (No. 14)—more so than Truvada, which got its first generic equivalent this year (No. 7).
