Vaccines based on whole inactivated virus (WIV) and protein-based platforms, as well as protein particle-based vaccines, are the most produced by LMIC vaccine manufacturing strategies. Three major WIV vaccines are beginning to be distributed widely. Several protein-based and protein particle-based vaccines are advancing with promising results. Overall, these vaccines are exhibiting excellent safety profiles and in some instances have shown their potential to induce high levels of virus neutralizing antibodies and T cell responses (and protection) both in nonhuman primates and in early studies in humans. There is an urgent need to continue accelerating these vaccines for LMICs in time to fully vaccinate these populations by the end of 2022 at the latest.
