A vaccine has been used to free a man who was trapped at home by a Covid infection that lasted for more than seven months.
It is the first time that a vaccine has been used to “treat” Covid rather than “prevent” it.
Ian Lester, 37, has a weakened immune system that was unable to defeat the virus on its own.
He says he became a prisoner in his home in Caerphilly, Wales, as he isolated for months on end.
Ian was born with Wiskott-Aldrich syndrome, which makes it harder for him to fight off infections. Even a common cold can linger.
He shielded during the first wave of Covid, but coronavirus eventually found him in December 2020. He had one of the classic symptoms – a slight loss of sense of taste and smell – which cleared up within a month.
