    Investigational COVID-19 vaccine tablet safely induces immune response in Phase I
    A preliminary analysis shows VXA-CoV2-1 was well-tolerated and induced T-cell and IgA responses against SARS-CoV-2 antigens in 35 patients.

    US and South Africa trials test oral vaccine whose capsule technology was developed in UK

    A US-based company, ImmunityBio, has acquired worldwide rights to technology developed in the UK to deliver Covid-19 vaccines in a pill or tablet form, and has now started clinical trials.

    ImmunityBio’s human adenovirus (hAd5) Covid-19 vaccine candidate is being tested in people in South Africa as well as in the US, following successful tests in non-human primates.

    The vaccine is designed to activate the immune system through virus-specific T-cells and to generate memory B-cells with neutralising antibodies, which ImmunityBio says could protect against emerging coronavirus mutations.
    An interview this morning on BBC News indicated that it is likely that the booster vaccine required for the autumn in the UK to cover the variants circulating would be supplied by tablet "through the post".
    “The only security we have is our ability to adapt."
