How effective is a single dose of Pfizer Vaccine in cancer patients?
Single dose is not very effective in cancer patients.
An UK study has now been peer reviewed and published in the esteemed Lancet oncology journal. The study showed inadequate protection after first dose.
More than half of the cancer patients receiving a single dose of the Pfizer COVID-19 vaccine have been left with little protection against the virus.
Two doses are critical and the second booster ideally need to be given on time at 21days.
