Covid vaccination improves effectiveness of treatment for cancer in nose-throat cavity

The Independent  

Cancer drugs worked better after patients had had Covid-19 jabs, scientists have discovered. Patients with nasopharyngeal cancer – in the area from the back of the nose to the upper part of the throat – who had had a coronavirus vaccine “responded significantly better” to treatment than unvaccinated patients, according to German and Chinese experts. They were surprised when the cancer drugs worked better in those who had had the jab, and concerns that the cancer therapy might interact unfavourably with Covid vaccination appeared unfounded. It is often treated with drugs that activate the immune system against the tumour, and until now, doctors feared that Covid vaccination could make cancer treatment less effective or cause severe side effects. “This risk is especially true for nasopharyngeal cancer, which, like the SARS Cov-2 virus, affects the upper respiratory tract.” Christian Kurts, director of Institute of Molecular Medicine and Experimental Immunology at the university, said: “Surprisingly, they responded significantly better to anti-PD-1 therapy than the unvaccinated patients.
