COVID-19 IMPACT 

COVID-19 Pandemic Infection Hampered R&D Operations and Renewed Awareness

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

Initially, interrupting ongoing clinical trials and research and development efforts as worldwide healthcare systems diverted attention and resources to handle the coronavirus epidemic, the COVID-19 epidemic impacted the market for HSV vaccines in two ways. Lockdowns, limited site access, and reordering of research activities stopped or slowed many HSV vaccine trials. The epidemic, though, also generated more clinical interest in HSV, especially as research showed a link between COVID-19 infections and a higher incidence of HSV reactivation, notably HSV-1. These co-infection patterns increased awareness of public health and revived interest in HSV preventative methods. Therefore, early failures notwithstanding, the epidemic acted as a catalyst, speeding research, increasing funds, and highlighting the pressing need for efficient HSV vaccination approaches.

HERPES SIMPLEX VIRUS (HSV) VACCINES MARKET SEGMENTATION

BY TYPE

Based on Type, the global market can be categorized into GEN-003, VCL-HB01, and HSV529

• GEN-003: Matrix-M2 adjuvant combined with HSV-2 antigens (gD & ICP4). Phase I/II experiments revealed reductions of up to 60% in lesion frequency and viral shedding. One of the first therapeutic vaccines to demonstrate some discernible efficacy in controlling recurring genital herpes was it. Post-vaccination, GEN003 also showed sustained immunological responses going several months. Its initial popularity drew attention to subunit-based therapeutic approaches for HSV-2 management.
• VCL-HB01: A DNA-based therapeutic vaccination encoding HSV-2 glycoproteins gD2 and VP11/12. Despite its safety, Phase II studies failed to significantly lower recurrence rates, hence stopping after 2018. The candidate, nevertheless, helped improve knowledge of DNA vaccination design and underlined the necessity of more potent immunostimulatory systems. Its stopping caused developers to turn their attention back to adjuvant upgrades and combination treatments. The knowledge acquired from VCLHB01 still shapes next-generation HSV vaccination strategies.
• HSV529: Sanofi Pasteur's HSV-2 candidate with defective replication has finished Phase I studies (20152018). Following Sanofi's pipeline reassessment, the ongoing developmental status remains unconfirmed. HSV529 sought to strike a balance between safety and efficacy for uninfected people as a non-replicating vaccine. Early recognition came for the candidate's unusual means of causing immunity free from the risks linked with live-attenuated vaccinations. Its ambiguous nature shows more general problems with funding and priorities for long-term HSV vaccines.

BY APPLICATION

Based on application, the global market can be categorized into HSV-1 (Oral Herpes), HSV-2 (Genital Herpes)

• HSV-1 (Oral Herpes): Though early R&D phases exist for vaccines, prevention offers a great advantage by easing recurrent cold sores. A vaccine directed at HSV-1 could dramatically lower social stigma and raise quality of life. Oral herpes, mostly treated with medications such as acyclovir, remains common. Researchers are looking at systems that may cross-protect against both HSV types. Though late to grow, candidates for the HSV-1 vaccine are drawing increasing scientific interest.
• HSV-2 (Genital Herpes): Genital herpes has more clinical relevance; hence, therapeutic vaccines like GEN003 attempt to lower outbreaks among infected people are closest to market permission, generating major market optimism. HSV-2 is linked to more severe symptoms and higher transmission rates, particularly in immunocompromised patients. An effective vaccine could also lower the risk with HIV. Growing public knowledge of HSV-2's burden is driving interest in therapeutic options.
