The emergence of variants with the ability to evade the immune system is driving a search for new development strategies and expanding the range of viral epitopes, which the new vaccines are designed to address. The first generation of vaccines targeted the virus's S protein, generating antibodies and T cells that recognize the receptorbinding domain (RBD), to prevent the virus from entering host epithelial cells.
Some of the new approaches to the development of COVID-19 vaccines are now undergoing clinical evaluation. For example, the RBD SARS-CoV-2 HBsAg VLP vaccine, which is in phase 1 and 2 clinical trials, is composed of protein subunits, virus-like particles (VLP), which are composed of the receptor binding domain (RBD) of the SARS-CoV-2 S protein, conjugated with hepatitis B surface antigen, obtained by recombinant DNA technology (rDNA). Additional information on clinical trials of this vaccine is available at:
Another vaccine under development, based on VLP technology, called GBP-510, consists of computer-designed protein nanoparticles obtained using rDNA technology. The size of the nanoparticles seems to favor immune transit to the lymph nodes. This vaccine is in phase 1 and 2 clinical trials.
For multivalent vaccines, the California Institute of Technology, in the United States, has reported promising immunogenicity data with an experimental multivalent vaccine using protein nanoparticles from different S protein receptors (RBD) from various human and animal coronaviruses. This vaccine appears to cause cross-reactive immune responses in mice, providing protection against strains that were not included in the experimental vaccine. In addition, protection against the B.1.351 lineage strain is being evaluated, with protection studies to be conducted in non-human primates

Guillain-Barré syndrome (GBS) have been reported very rarely following vaccination with Vaxzevria [21].
The benefits of the vaccine outweigh the risks of GBS [2]; [3].
TTS in some cases accompanied by bleeding, has been observed very rarely following vaccination with Vaxzevria. This includes severe cases ans unusual sites such as cerebral venous sinus thrombosis, splanchnic vein thrombosis, as well as arterial thrombosis. Some cases had a fatal outcome. The majority of these cases occurred within the first three weeks following vaccination. The reporting rates after the second dose are lower compared to after the first dose [21].
Vaxzevria is contraindicated in persons who have experienced TTS with previous doses of the vaccine [2].
Very rare cases of capillary leak syndrome (CLS) were reported in the first days after vaccination with Vaxzevria, with fatal outcomes in some people with prior experience of CLS. EMA recommends that persons with a known history of CLS should not be vaccinated with Vaxzevria [5] [21].
Events of cerebrovascular venous and sinus thrombosis (CVST) without thrombocytopenia have been observed very rarely following vaccination with Vaxzevria, mostly within the first four weeks following vaccination. This information should be considered for individuals at increased risk for CVST [3].
Very rare cases of thrombosis with thrombocytopenia syndrome (TTS) were reported globally (0.081 cases per 100.000 vaccinees as of December 2021) around 3-30 days following vaccination with CanSino [1].

GBS has been reported very rarely following vaccination with Janssen COVID-19 vaccine. As of April 2022, 535 cases were reported globally (1.5 cases per million vaccinees) [6], [18]
The benefits of the vaccine outweigh the risks of GBS [6].
Very rare cases of thrombosis with thrombocytopenia syndrome (TTS) were reported following the first dose of Janssen COVID-19 vaccine.
