AstraZeneca PLC said Friday that it will collaborate with Russia's Gamaleya Research Institute to combine its own vaccine candidate with Gameleya's Sputnik V vaccine.

The pharmaceutical group said repeated administration of a vaccine is likely to boost immunization efficacy, both in case of multiple shots of the same vaccine or combining different ones.

The company said it is therefore exploring ways to assess heterologous combinations of different vaccines, including cooperating with the Gamaleya Research Institute to understand whether two adenovirus-based vaccines can be successfully combined.

AstraZeneca said assessing different types of Covid-19 vaccines in combination could help unlock synergies in protection and improve vaccine accessibility.

"It is clear that to overcome the Covid-19 pandemic, more than one vaccine will be needed," it added.
