More than 100 million people worldwide are thought to have post-acute COVID-19 syndrome, roughly 40% of everyone on the planet who’s had COVID. Now, thousands of them are beginning to cycle through clinical and preclinical studies designed to get a better look at this little understood aspect of the pandemic.

The number of biopharma deals with nonprofits or government entities has dropped over last year, partly due to fewer COVID-19-related alliances, but the activity in 2022 is still strong in comparison to pre-pandemic years.

It's neither a retrovirus nor an opportunistic infection. But of course, SARS-CoV-2 has a prominent place at the table at the 2022 Conference on Retroviruses and Opportunistic Infections (CROI) – starting with the fact that COVID-19 has again forced the conference to go virtual.

The overwhelming focus of research into the cellular immune response to SARS-CoV-2 has been investigating the reaction of vaccinated people, in an effort to establish correlates of protection required to fight off infection. But with a majority in many African and Asian countries still unvaccinated, it also is important to understand the natural cellular immune response, and to track the emergence of SARS-CoV-2 variants with the potential to escape immunity in these populations.
