The Joint Committee on Vaccination and Immunisation (JCVI) has reviewed preliminary data from the Clalit Research Institute on vaccine effect, including the vaccine effectiveness estimate at day 14 after the first dose of the Pfizer-BioNTech vaccine. The JCVI concluded that the results are preliminary and there is a need for greater clarity, including full information on the dataset, before further consideration or comment. The JCVI will review this data carefully once the full study details are released.
