The Covid-19 pandemic has created major dilemmas for providers in all areas of health care delivery, including cancer centers. We are still fighting this global hazard. Now we are at a stage where COVID vaccine has emerged as an effective tool. Cancer is included in list of comorbidities which make any person vulnerable to COVID infection irrespective of age. Here we try to resolve most of queries asked by cancer patients regarding COVID vaccines.
COVAXINE: an inactivated vaccine which means that it is made up of killed coronaviruses. Bharat Biotech utilized sample of virus, isolated by India's National Institute of Virology.
When administered, immune cells can still recognize the dead virus, prompting the immune system to make antibodies.
COVISHIELD: made from a weakened common cold virus, called as adenovirus from chimpanzees. It has been modified to look like coronavirus. When the vaccine is injected into a patient, it prompts the immune system to make antibodies.
Cancer patients on active treatment are included in clinically vulnerable group. These patients include those on chemotherapy, on radiation, undergone recent major surgery or splenectomy, elderly patients.
Yes. All of the COVID-19 vaccines available in India are safe for their recommended use
People with cancer have a higher chance of severe symptoms if they get COVID-19 and vaccine is an effective protection.
NCCN COVID-19 Vaccination Advisory Committee recommend that Patients with active cancer and those on treatment should be prioritized for vaccination and should be immunized with any vaccine that has been authorized.
European Society of Medical Oncology (ESMO) guideline states: “Patients with cancer have an increased risk of severe Covid-19, ie, haematological malignancy requiring chemotherapy or active, advanced solid tumour or history of solid tumour less than 5 years ago and should be vaccinated against SARS-CoV-2 regardless of any other indications (ie, age), and positioned at high prioritisation.”
People with cancer weren’t included in the clinical trials of the COVID-19 vaccines. While the COVID-19 vaccines are very safe, researchers do not know exactly how much protection they will give people with cancer compared to those who do not have cancer.
However, the way the vaccines work means that there is a strong chance that your immune system will learn to protect you, to some degree, from COVID-19.
If you are on treatment or your treatment needs to start before you can get the vaccine, do not delay your cancer treatment.
Systemic Therapy: If you are on cyclical therapy, for example chemotherapy given every 3 weeks, try and book your vaccine around 1 week before your next treatment. Blood cell counts is checked beforehand.
Researchers says between 0.6% and 1.6% of patients develop COVID-19 infection after elective surgery. Patients who develop COVID-19 infection are 4-8-fold increased risk of death in the 30 days following surgery. For example, whereas patients aged 70 years and over undergoing cancer surgery would usually have a 2.8% mortality rate, this increases to 18.6% if they develop COVID-19 infection. Vaccination policy should consider this datas.
Presently vaccination drive is to mass vaccinate the population as per government regulations and registration. It is more important to receive vaccine and have second dose same as first dose. Both vaccines are effective.
Yes, it very important to follow all routine measures like wearing a mask and social distancing. As a society it is also our responsibility of protect each other. Together we’ll overcome this problem.
Experts recommend to consider vaccination of all adult patients who had a cancer diagnosis within the last five years, whether on treatment or not, and irrespective of any age cut-offs.
