Vaccines Approaches in COVID-19 Vaccine Development

HIV represents one of the most challenging viruses ever encountered. Though an HIV vaccine has yet to be licensed, vaccine science has made enormous strides as it confronts this rapidly-mutating virus. Years of painstaking work to develop vaccines for HIV are now making possible the record-breaking timelines that researchers aspire to for the development of COVID-19 vaccines. Vaccines research has generated more scientific knowledge about immune function and responses than ever existed. And key vaccine platforms are fast-tracking the development and testing of experimental vaccines for COVID-19 today.

The Race for a Coronavirus Vaccine

Will compressed and overlapping steps get a vaccine faster? The innovations advocated for in Vaccines development that are being employed in the COVID-19 response today include: running certain clinical trials in parallel instead of sequentially; gearing up manufacturing capacity before final study results are in and negotiating public/private commitments in advance to facilitate sustainable access to new vaccines.

Leveraging the Vaccines Enterprise for COVID-19 Vaccine Research

In many ways, the collaborative research movement grew up around Vaccines. Thanks in large part to HIV advocacy, out-of date research models that were competitive and closed-door are increasingly yielding to more transparent and collaborative research and development efforts—in both the HIV and COVID-19 responses.

Building on big science partnerships, data sharing and collaboration pioneered over the last 15 years of Vaccines research and development, global initiatives are marshalling the talents, experiences and resources of key stakeholders. And just as HIV laid the foundation for more effective partnerships in research, lessons from the COVID-19 experience can also inspire greater collaboration and broader involvement by a range of players in the vaccines research effort.

Voluntary Medical Male Circumcision for HIV Prevention (VMMC): An introductory factsheet

This introductory 2-page document explains how VMMC works, reviews the scientific evidence behind it, and outlines key advocacy issues for implementing it.

Vaccines Research Pipeline

This graphic shows the many types of Vaccines undergoing research, categorized by the immune response they are designed to elicit—broadly neutralizing antibodies, non-neutralizing antibodies, T-cell responses or a combination of these.

AVAC Report 2019: One-pager

Each year, the AVAC Report frames the most pressing advocacy issues facing the HIV response. At the threshold of 2020, it’s clear that global goals for HIV prevention will miss the mark by a long shot. Now what?

This is a one-pager summarizing AVAC’s priorities for 2020. To download the full Report or see all its graphics, visit report.avac.org.

AVAC’s “3D” View of the World: 2019 and beyond

This infographic lays out AVAC’s top-line recommendations from AVAC Report 2019: Now What? The recommendations fall into three categories: deliver — prevention programs whose impact is well-measured and -defined; demonstrate — next-generation engagement for next-generation trials; develop — new targets for the post-2020 world.

Universal Test and Treat (UTT) Trial Results

As this table shows, the two trials that offered community-wide testing in both arms (SEARCH, TasP) did not find a difference in incidence between the arms. One explanation may be that the expanded access to testing and linkage in both arms had an impact in both intervention and control communities. The two trials that only provided universal testing in the intervention arm identified differences in incidence between that arm and the control arm.

There were other differences between the four UTT trials. As described below, PopART was the only trial with urban and peri-urban communities.

AVAC Report 2019: Now What?

Each year, the AVAC Report frames the most pressing advocacy issues facing the HIV response. At the threshold of 2020, it’s clear that global goals for HIV prevention will miss the mark by a long shot. Though important progress has been made, the crisis UNAIDS called out in 2016 persists today with new infections around 1.7 million annually, a far cry from the 2020 target of fewer than 500,000. So, we asked ourselves, Now What?, and answered with cross-cutting analysis and an advocacy agenda to match.

Vaccine Strategies in the Pipeline

Scientists are studying these strategies to develop an effective vaccines and deliver it into the body in a way that maximizes the immune response.
