Griffiths was among those who gave evidence to the 1802 Committee of the House of Commons on Dr JENNER'S Petition respecting his Discovery of Vaccine Inoculation against small pox, recently discovered by Edward Jenner. In his evidence, Griffiths indicated that he had inoculated upward to fifteen hundred persons, none of whom has had untoward symptoms, among them three of his own children, at various periods within three years.

Griffiths married Elizabeth, the daughter of Sir William Neville Hart M.P. and Elizabeth Aspinwall, on 4 June 1787 and had issue. Griffiths died on 17 September 1822 and his wife Elizabeth on 16 April 1824. They are both buried in the graveyard of St Andrew's Parish Church, Charmouth, Dorset.
