The Capability of Haemato-oncology Patients to Generate Antibodies Against COVID-19

Study Overview
=================
Brief Summary
-----------------
The corona pandemic is a continuing global challenge due to Corona Virus 2019 (COVID-19). The purpose of the study is to evaluate the capability of Haemato-oncology patients to generate antibodies against COVID-19 after infection and vaccination.

Detailed Description
-----------------
In December 2019, a backlog of patients with respiratory disease was identified in Hubei Province, China. The number of infections increased rapidly, and more patients were identified in other provinces in China, and in various countries in the Far East, Europe and the United States. With few exceptions, patients became infected while staying in China. The cause of the disease has been identified as a virus from the corona family - SARS-CoV-2 and the new name given to the disease. (COVID-19) Coronavirus disease The virus belongs to a family of respiratory viruses that often cause mild respiratory illness, however, viruses from this family have also caused epidemics of severe respiratory infections. On March 11, 2020, the World Health Organization declared the corona virus a global pandemic. The average incubation period (from exposure to the onset of clinical symptoms) is 6 days, with a range of 2 to 11 days. Common symptoms of coronary heart disease include: fever, cough, shortness of breath, muscle aches.Some patients develop complications, including pneumonia, respiratory failure, myocarditis and death. Similar to other respiratory viruses, 2019-nCov is transmitted by respiratory droplets. Diagnosis is made by PCR examination from a sample of the upper respiratory tract (pharynx and nose). In the literature accumulated in recent months suggests that haemato-oncology patients are at increased risk for severe corona disease and mortality. In haemato-oncology patients the recovery process from corona may be prolonged, including a prolonged secretion of the virus compared to a healthy population. The study population: CLL, Multiple Myeloma or Lymphoma patients as well control group of healthy patients who are vaccinated with COVID-19 in a commercial preparation, regardless of the study. Serology test between two and three weeks after the second dose of the vaccine to test the effectiveness of the vaccine will be performed as part of the study .During the follow-up period in patients who have developed antibodies to the virus, patients will be offered to repeat the serological test after six months, irrespectively of whether they received a third vaccine within the Israeli standard of care. All data collected in the study will be typed into Excel and analyzed using SPSS version 21.0. Continuous data will be described using averages and standard deviations, and categorical data will be described using prevalence and percentages.

| --- | --- | --- |
| Capability of Haemato-oncology patients to generate antibodies against COVID-19 after infection and vaccination. | Evaluate the capability of Haemato-oncology patients to generate antibodies against COVID-19 after infection and vaccination by using serology tests. | 14 to 21 days counting since second vaccination is initiated. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
