HIPRA, a biotech company that provides vaccines and diagnostic services, developed Bimervax, which combines part of the SARS-CoV-2 virus spike protein with an additional ingredient designed to trigger a stronger immune response, known as an adjuvant.
The new COVID-19 vaccine will be given as a booster injection to eligible individuals aged 16 years and over.
The regulator’s decision was based on data from a study of 765 adults who received primary vaccination with two doses of the Comirnaty COVID-19 vaccineCOVID-19 vaccine and then a booster dose of either Bimervax or Comirnaty.
Bimervax showed a strong immune response, and common side effects were mild and self-resolved within a few days of vaccination.
The MRHA’s authorisation comes less than a month after HIPRA said it would be initiating a clinical trial to evaluate the safety and immune response of Bimervax when co-administered with the seasonal influenzavaccine.
The study, which will involve 300 adults aged 65 or older who were first vaccinated against COVID-19 with an mRNA vaccine, has been authorised by the Spanish Agency for Medicines and Health Products and will last two months.
The MRHA authorised SK Chemicals’s SKYCovion earlier this year for use as a primary vaccination in those aged 18 and over, making it the eighth COVID-19 vaccineCOVID-19 vaccine to be approved by the regulator.
Its decision was based on data from two clinical trials of approximately 3,100 individuals between the ages of 18 and 84. SKYCovion demonstrated a strong immune response, with only mild common side effects that resolved on their own soon after vaccination.
