A study led by Pirbright scientists investigates how COVID19 vaccinations and boosters help the immune system fight SARS-CoV-2
Scientists at Pirbright show that immunity to SARS-CoV-2 decreases over time after vaccination, but that a booster could help restore this immunity and can help the immune system recognise new variants of the virus, including Omicron BA.1 and BA.2.
Vaccination against SARS-CoV-2, the virus that causes COVID-19, has been pivotal in the protection of populations across the globe, especially older adults and the clinically vulnerable.
