UK study finds mRNA COVID -19 vaccines provide biggest booster impact

COVID -19 vaccines made by Pfizer and Moderna that use mRNA technology provide the biggest boost to antibody levels when given 10-12 weeks after the second dose, a British study published on Thursday has found.

Register"A third dose will be effective for many of the vaccines we've tested and in many different combinations," Professor Saul Faust, an immunologist at the University of Southampton and the trial's lead, told reporters.The study found that a full dose or half dose of Pfizer or a full dose of Moderna gave a very effective boost to both antibody and T-cell levels, regardless of whether the person initially received Pfizer or AstraZeneca.

When AstraZeneca, Novavax, Johnson & Johnson and Curevac were given as boosters, they increased antibody levels for either initial vaccine, albeit to a smaller degree. However, while Valneva boosted antibodies in people initially vaccinated with AstraZeneca, it did not provide a boost for Pfizer.

The study found that booster shots also helped to generate a broad T-cell response against the Beta and Delta variants, which may play a key role in longer-term protection."T-cell (response) does seem to be broader against all the variant strains, which gives us hope that a variant strain of the virus might be able to be handled, certainly hospitalisation and death, if not prevention of infection, by the current vaccines," Faust said.

The study pre-dated the spread of the Omicron variant of concern, but Faust said he had shared samples with the UK Health Security Agency to generate data on Omicron as well.Register now for FREE unlimited access to reuters.comRegisterReporting by Alistair Smout; Editing by Bernadette Baum
