A US study of COVID-19 vaccines in 184,485 cancer patients found that, overall, they were 58 per cent effective 14 days after the second jab. The vaccines were least effective in patients who had received chemotherapy less than three months before the first jab at 57 per cent, while vaccines were 76 per cent effective in patients receiving hormone therapy, and 85 per cent effective in patients who had not received any therapy for six months before the first jab. Despite this reduced effectiveness, vaccination still cut cases of COVID-19 - 47 days after the jabs, there were 275 COVID-19 infections in unvaccinated patients, compared with 161 in the vaccinated group. The results suggest vaccination cuts infection rates in cancer patients, especially among those not receiving therapy and those receiving hormonal treatment.
